Category 2 - Front Suspension

02-04-00 A All Squeaking/clicking noise from rear leaf springs.
If the vehicle has a squeaking/clicking noise coming from the rear of the vehicle, verify that the noise is coming from the rear springs as the vehicle’s suspension goes through jounce and rebound. If a squeaking/clicking noise is coming from the rear springs, perform the repair procedure. The procedure involves replacing the spring tip liners and installing spring clinch clip insolators.
02-001-01 All Rear of vehicle sits too high to allow hook up to a fifth-wheel trailer.
This bulletin applies to 2500 and 3500 4x4s. The curb hight lowering package is designed to reduce the rear spring spacer block by 1 7/8 inch, which will lower the rear of the vehicle by several inches proving clearance so that most customers can attach their fifth-wheel or goose neck trailer to the trailer hitch turntable.
02-003-02 All Toe-in specification change.
This bulletin involves an update to the toe-in specification for front end alignments. The specification for toe-in has been revised to 0.2° +- 0.1° total toe in. This change has been shown to improve straight ahead driving performance and should be used whenever a front end alignment is performed.

Category 3 - Rear Axle

Category 5 - Brakes

05-06-00 All Front brake caliper anti-rattle clip retainer service procedures.
This bulletin applies to vehicles built before June 26, 2000. Vehicles built between April 19, 2000, and June 26, 2000, were built with a front brake caliper anti-rattle clip retainer. This Technical Service Bulletin provides the installation procedures for the retainer.
05-002-01 All Parking brake pedal adjustment.
This bulletin applies to 2500/3500 series Ram trucks with four-wheel disc brakes, built before November 20, 2000. Parking brake cable appears to be mis-adjusted, which may cause the parking brake lamp to remain illuminated even after the parking brake pedal has been released. The parking brake system, however, is not mis-adjusted and functions normally. Install new parking brake cables.

Category 6 - Clutch

Category 7 - Cooling

Category 8 - Electrical

08-18-00 All Radio Interference to/from two-way radio receivers.
Customers may complain of intermittent poor reception on their two-way radios. This bulletin involves installing a RFI filter in series with the electric fuel pump motor.
08-23-00 All Plastic boot to protect the electrical harness B+ end terminal at the generator.
While service is being performed to the engine, it may be possible for a momentary electrical short to occur. The electrical short may be caused when a metallic object, such as a wrench or oil filter, comes in contact with the B+ end terminal of the generator wire harness. The B+ end terminal is bolted to the generator B+ stud (output terminal). The B+ stud on the generator is protected by a plastic surround. Part of the wire harness end terminal may extend beyond the protective plastic surround for the B+ output terminal.

This bulletin applies to vehicles equipped with a 5.9L – 24V diesel engine built before engine serial number 56681800 with a date of manufacture of January 29, 2000. The repair procedure involves the installation of a protective rubber boot (part number 04487042) over the B+ terminal.
08-26-00 All Central timer module electrically “locks-up.”
This bulletin applies to vehicles equipped with remote keyless entry (sales code GXR). In addition, this bulletin applies to vehicles built on or before the following build dates: Ram trucks built at the St. Louis North Assembly Plant on or before August 21, 2000; Ram trucks built at the Saltillo Truck Assembly Plant on or before August 31, 2000; Ram trucks built at the Lago Alberto Truck Assembly Plant on or before September 6, 2000. The repair involves replacing the Central Timer Module (CTM) with a revised part.
08-041-00 All Intermittent locking/unlocking of doors without activating the door lock switch.
This bulletin applies to vehicles equipped with vehicle theft security system (sales code LSA).

The door locks will intermittently lock and/or unlock without any activation of the power door lock switch or a clicking sound may be heard coming from the power door locks (repeated locking or repeated unlocking). The condition may occur more frequently in damp conditions such as driving the vehicle in the rain or taking the vehicle through a car wash.

Vehicles that demonstrate this condition may have water weeping into the door/liftgate lock cylinder switches causing the switch to intermittently short across the internal circuit. This in turn may signal the Central Timer Module (CTM) to activate the power door locks. Because of the nature of this problem it is extremely difficult to diagnose this condition. Customers that indicate their doors intermittently lock and unlock without having the door lock switch activated or customers that indicate they hear a repeated clicking noise coming from the door locks should have the repair procedure performed on their vehicle.
08-010-01 All Airbag/clock spring service.
When servicing any airbag system, it is essential to follow the proper Service Manual and/or Diagnostic Manual procedures for diagnosing, testing, and replacing of any component. Do not use silicone or any other lubricant spray on or near the clock spring. Lubricants are often used in the clock spring area of the steering column to eliminate noise. Any repair that may disrupt the positioning of the steering wheel with the front wheels will require that the clock spring be centered. This includes clock spring replacement, steering column service, HVAC service, steering gear service, and front suspension crossmember service.

Category 9 - Engine

09-001-01 All Intermittent loss of oil pressure sensor ouput voltage.
This bulletin applies to 2500/3500 diesels with engine serial number 56744083 to 56809910. The output voltage of the oil pressure sensor may intermittently dropout. This condition may cause the engine oil pressure gauge needle to erroneously indicate lower than actual oil pressure. A warning chime may sound and the “Check Gauges” lamp may illuminate. The Engine Control Module (ECM) software has been revised to address this condition. Replacing the oil pressure sensor will not correct this condition.
09-002-01 All Exhaust manifold bolt retention straps.
This bulletin applies to vehicles equipped with a 24-valve diesel engine built on or between engine serial number 56419738 and 56777585, with a date of engine manufacture from January 01, 1998 to September 22, 2000. This information is available on the engine data plate, which is located on the left side of the engine, affixed to the side of the timing gear housing.

Vehicles that are used for extended heavy trailer hauling purposes may experience a loss of exhaust manifold bolt torque. This condition may lead to exhaust gas blow-by past the exhaust manifold gasket(s) and even loss of exhaust manifold bolts.

A new exhaust manifold bolt retention strap has been released as a means of locking the outboard exhaust manifold bolts in place. This will prevent bolt rotation and torque loss during the thermal expansion and contraction cycles of the exhaust manifold.
09-003-01 All Engine oil additives/supplements.
(EOS) should not be used to enhance engine oil performance. Engine oil additives/supplements should not be used to extend engine oil change intervals. No additive is known to be safe for engine durability and can degrade emission components. Additives can contain undesirable materials that harm the long term durability of engines. Generally it is not desirable to mix additive packages from different suppliers in the crankcase; there have been reports of low temperature of low temperature engine failures caused by additive package incompatibility with such mixtures.
09-004-01 All Engine lubricant.
This bulletin involves 1989-2001 Ram trucks equipped with the 5.9L Cummins diesel engines. This bulletin discusses the recommended oil filters for use with Cummins 5.9L diesel engine.

The information only bulletin was issued to alert the field to problems caused by aftermarket oil filter. For example, neoprene compounds used internally in the manufacture of oil filters not recommended by DaimlerChrysler may seperate from the filter, lodge in the piston cooling nozzle, and cause the engine to fail. THIS IS NOT AN ENGINE DEFECT.
09-006-01 All Engine Oil Pan Gasket Sealing
This bulletin applies to Ram trucks equipped with the 24-valve diesel engine. Repeated oil pan gasket leaks can occur on 24-valve diesels if the gasket is applied without the use of Mopar Silicon Rubber Adhesive (RTV) Sealant (PN 04883971). This bulletin provides routing of the sealant when replacing the engine oil pan gasket. When replacing an oil pan gasket, apply a 1/8" bead of RTV to the oil pan side of the gasket , around the back of the engine, extending up to the fourth bolt hole from the rear on each side, as per the referenced diagram.
09-002-02 All Crankcase Breather Overflow
This bulletin applies to 1998-2002 (BR) Ram trucks equipped with the 24-valve Cummins diesel engine built after March 27, 1998 (engine serial number 56443872). Owners of these vehicles may experience engine oil overflow from the front crankcase breather when the vehicle is operated off-road on an extreme downhill grade (37.5% or 22° slope/grade). Operation of this type for extended periods of time can cause enough engine oil depletion to damage the engine. A kit containing all components necessary to eliminate the oil overflow has been made available. If the condition exists, perform the repair procedure outlined in this bulletin. The repair involves the addition of a new breather kit.
09-008-02 All Engine knock or rattle sound when climbing a long grade and towing a heavy trailer.
This bulletin applies to 1998-2002 Ram trucks equipped with the 24-valve Cummins diesel engine (sales code ETC or ETH). Owners may experience an engine knock or rattle sound when climbing a long grade while towing a heavy trailer. If the condition exists, replace the engine thermostat as outlined in the service manual. Note: Mopar 05015708AC is to be used exclusively for this service bulletin.

14-02-00 All Crack in diesel fuel filter housing cover caused by an improper servicing procedure.
This bulletin applies to vehicles equipped with a 5.9L-24V diesel engine built before engine serial number 56686747 with a date of manufacture of February 09, 2000. Analysis of returned fuel filter housing covers has determined that a number of plastic covers are being replaced due to cracks. Further analysis has revealed that the cracks may be caused by improper cover removal procedures. Do not use the square opening to remove or install the cover. The fuel filter cover may crack. To remove or install the fuel filter cover correctly, only use the 1 1/8” hex head. Use of a six point socket is preferred.
14-03-00 All Maintenance to the Water-In-Fuel sensor probes due to possible fuel contamination.
The probes on the end of the Water-In-Fuel (WIF) sensor may become less effective at sensing the presence of water in the fuel if they are exposed to contaminated fuel. Contaminant from the fuel may insulate the WIF sensor probes and inhibit the WIF lamp from illuminating when water is present.

Any time service is performed on the fuel filter or fuel filter housing, the probes on the end of the Water-In-Fuel sensor should be cleaned. Use a clean cloth to wipe the WIF probes of any contaminant.
14-002-02 A All Tampering with VP44 fuel pump on Cummins diesel engine.
This bulletin supersedes technical service bulletin 14-002-02, dated July 1, 2002. A number of the VP44 fuel pumps have been returned through the warranty process as a result of tampering. Generally, the customer complains that the vehicle dies while driving. When diagnosed, there may or may not be Diagnostic Trouble Codes (DTC) present. When DTCs are present, there may be one or more of the following:
DTCP CodeDescription
124P 0234Turbo boost limit exceeded.
146P 0217Decreased engine performance due to engine overheat condition.
361P 0254Fuel injection pump fuel valve current too high.
363P 0251Fuel injection pump mechanical failure fuel valve feedback circuit.
364P 1689No communication between ECM and injector pump module.
375P 0602ECM fuel calibration error.

The diagrams show the area where performance enhancing equipment is being connected into the outboard wire of the two wires that control operation of the metering solenoid in the pump. Another type of device places a connector between the metering solenoid harness and the upper connector on the pump. Telltale evidence can be seizure of the pump rotor, and/or cracked or overstressed pump cam ring. The protective sleeve around the two wires may be rolled or cut back to gain access for connection. Injection pumps that have been tampered with are not warrantable.

Category 16 - Propeller Shafts & U-joints

Category 18 - Vehicle Performance

18-015-00 A All Driveability enhancements for winter fuel use and for hard starts.
This bulletin applies to vehicles equipped with a 5.9L-24V diesel engine built between engine serial numbers 56419738 to 56798357, with a date of manufacture of December 16, 1997 to November 15, 2000.

The customer may complain of poor driveability when winter fuel is used to power the engine. Or, the customer may complain of a hard or no-start condition, while the engine is at normal operating temperatures, when using any type of good quality diesel fuel. The poor driveability condition may occur only when either straight #1 diesel fuel is used or when other special cold climate winter blend fuels are in use.

The no-start or long engine crank condition may occur when attempting to restart the engine while the temperature of the engine is till close to its normal operating temperature. This hard hot restart condition may be experienced in all ambient climates, but may be more of a concern in warmer ambient climates. The repair involves selectively erasing and reprogramming the Cummins CM551 Engine Control Module (ECM) with new software.
18-024-00 All Low engine power when the automatic transmission is in overdrive.
This bulletin applies to vehicles equipped with a 24-valve diesel engine and automatic transmission built between engine serial numbers 56666444 to 56798357, with a date of manufacture of December 15, 1999 to November 15, 2000. This information is available on the engine data plate, which is located on the left side of the engine, affixed to the side of the timing gear housing.

The customer may complain of low engine power and/or poor performance. This engine condition may occur while the automatic transmission is being operated in its overdrive gear. This condition may be further aggravated if the customer is using the vehicle for towing purposes.

The Engine Control Module (ECM) software, on a 2001 Ram Truck equipped with a 24-valve diesel engine, is designed to “torque manage” the power output of the engine. This is done to protect the automatic transmission components. The revised software calibration restores the power output and improves the vehicle performance in overdrive.

Note: If TSB 18-015-00 Rev A has previously been performed too the vehicle in question, then the ECM software has already been revised with the correct calibration to address the above condition. The ECM will not require reprogramming.

The repair procedure involves selectively erasing and reprogramming the Cummins CM551 Engine Control Module (ECM) with new software (calibration versions: 56T13, 59T6). There is no change to the JTEC PCM software.
18-014-01 All Performance enhancement for severe cold weather environments.
This bulletin applies to all Ram trucks equipped with a 5.9L 24-valve Cummins diesel engine with a 49-state emissions calibration and an automatic transmission. The bulletin describes how to selectively erase and reprogram the Powertrain Control Model (PCM) with new software (59t7a). The problem addressed by the PCM reprogram is a hard starting and/or idle speed fluctuations condtion.

Cummins 24-vavle engines used with automatic transmissions can be severely affected by the use of sub-grade #1 diesel fuel when ambient temperatures are below 0°C (32°F), typically prevalent during the Winter months in Alaska, Northwestern Canada, and similar climates/temperatures elsewhere.

This change will have no effect on performance during warm weather or when standard grade diesel fuels #1 or #2 are used.

Vehicles with 49-state certification can apply this calibration if needed. The calibration can be changed back to the original calibration if desired.
18-019-01 All 24v engines Cold idle engine warming.
This bulletin involves selectively erasing and reprogramming the Engine Control Module with new software. This bulletin applies to all Ram trucks built after December 17, 1997 equipped with the 24-valve 5.9L Cummins diesel engine.

Extended idle operation, especially in cold weather, can allow varnishes/oils to condense on the exhaust valve stems, leading to stuck valves, and damaged valve train components. The repair procedure involves calibration software that will activate when certain parameters are met, reducing the chance of valve sticking as well as improving cab heat warm-up time. Idle speed will slowly ramp up from 800 rpm to 1200 rpm when all of the following conditions are met:
* Intake Manifold Temperature less than 60°C (32°F)
* Coolant Temp is less than 60°C (140°F)
* The transmission is in Neutral or Park
* The Service Brake pedal is not depressed
* Throttle = 0%
* Vehicle Speed = 0 mph

If intake manifold temperature (IMT) is less than -9°C (15°F), three of the cylinders will be shut off upon reaching 1200 rpm, creating a slight change in engine sound which is normal. Thus the engine has to work to overcome the three “dead” cylinders. This allows the engine to create increased heat in the cooling system, allowing more rapid warm up.

Either feature will abort when any one of the following occurs:
* The automatic transmission is placed in gear (forward or reverse)
* The service brake pedal is depressed
* Throttle position is greater than 0%
* Vehicle speed greater than 0 mph
* Coolant temperature is greater than 79°C (175°F)
18-030-03 All Generic Cummins engine control module (ECM) procedure.

Category 19 - Steering

19-009-01 All Driver airbag trim cover service.
Driver airbag trim cover/horn switches for the above vehicles are serviceable and as such when applicable, must be used instead of replacing the airbag module assembly. Airbag module assemblies returned for trim cover and serviceable horn switch issues, are subject to charge back.

The horn switch is integral to the driver airbag unit. Only DaimlerChrysler-trained and authorized dealer service technicians should perform service of this unit. Failure to take the proper precautions or to follow the proper procedures could result in accidental, incomplete, or improper airbag deployment and possible occupant injuries.
19-003-02 All Hissing sound coming from the power steering system on vehicles equipped with hydroboost brakes.
A hissing sound may be present in the power steering system during steering maneuvers or straight ahead driving. This bulletin involves replacing the power steering hoses connecting the hydroboost to the power steering pump and gear.
19-005-03 All Power steering fluid usage.
The factory fill power steering fluid for most 2004 model year Chrysler Group vehicles is ATF+4 (part number 05013457AA/S9602) and it provides superior performance at both low and high temperatures. Refer to the table to identify factory fill and the approved service power steering fluid by year and model. From the table it is noted that the ’94 to ’02 truck uses part number 04883077/MS5931.

MS9602 should not be mixed or used as a "topping off" fluid on systems requiring MS5931.

Category 21 - Transmission

21-12-00 All Tapping/knocking sound during idle.
This bulletin applies to vehicles built before May 10, 2000, equipped with an automatic transmission. A tapping/knocking sound may be heard or felt in the driver side floor pan area during idle conditions. With the engine running at an idle, listen for knocking sound coming form the driver side floor pan area. If a tapping/knocking sound can be heard, replace the shift linkage with revised parts.
21-004-01 All Overdrive disabled to improve transmission reliability during cold temperature operation.
This bulletin applies to vehicles equipped with an automatic transmission where the vehicle was built on or between June 26, 2000 and December 23, 2000, and the PCM software level is earlier (lower) than calibration 14 for model year 2001.

Quality analysis has determined that insufficient lubrication of certain internal transmission components may occur when a vehicle is operated in temperatures lower than -20°C (-5°F). This condition may be caused by the automatic transmission fluid (ATF) freezing in the cooler lines and interrupting the flow of lubricating oil (ATF) to the transmission overdrive unit. This condition should be a concern only in areas where very cold ambient temperatures of -20°C (-5°F) are experienced.

The revised software will not allow 4 th gear overdrive to occur if ambient temperatures are less than -20°C (-5°F). The revised PCM software has been implemented to improve transmission reliability. The customer should be informed that reduced fuel economy would be expected when overdrive is not in use.

The repair involves selectively erasing and reprogramming the Powertrain Control Module (PCM) with new software (calibration level 01Cal14).
21-009-01 All NV5600 Countershaft service.
This bulletin involves Ram trucks manufactured prior to March 17, 2001, and equipped with the NV5600 6-speed, heavy duty transmission. Customers may experience a shifter vibration (commonly referred to as "gear clash") of the shift knob when shifting from one gear to another between 2500 and 3500 rpm after a cold start up. This condition is most evident when ambient temperatures are at or near 0°C (32°F) but can occur at warmer temperatures as well. The condition is most often reported on 3rd to 4th gear shifting, but can occur in the other shift ranges as well. The problem can be verified by assuring the transmission is at ambient temperature, vehicle moving and, with the engine at 2500 to 3500 RPM, shifting into and out of the gear ranges

This repair may include disassembly of the countershaft assembly, requiring the use of a 20-ton press. Attempts to use lesser equipment to effect this repair could result in damage or injury.

If such a press is available, rebuilding the countershaft assembly is preferred. In the event a press is not available, a new countershaft assembly (PN 05073361AA) has been made available.

follow the service procedures in teh appropriate service manual to complete necessary repairs. Follow normal warranty procedures to report the repairs.
21-006-01 Auto trans Automatic transmission fluid usage ATF+4 (Type 9602).
This information only bulletin supersedes technical service bulletin 21-16-99, date October 22, 1999. The bulletin discusses a new transmission fluid (ATF+4 - Type 9602) which has been developed and is being used as factory fill for all vehicles with Chrysler automatic transmissions. Until now, vehicles originally filled with ATF+2 or ATF+3 were to be serviced with ATF+3. Effective immediately, it is recommended that all vehicles with Chrysler automatic transmissions except for 1999 and earlier minivans be serviced with ATF+4. ATF+3 should continue to be used for 1999 and earlier minivans because of the potential for torque converter shudder during break in. For all other applications the ATF+4 fluid offers significant benefits as outlined below.

ATF+4 must always be used in vehicles that were originally filled with ATF+4.

Service intervals do not change. The service interval currently in effect for a given vehicle should continue to be followed.

ATF+4 is compatible with ATF+3 and can be used to top off vehicles that currently have ATF+2 or ATF+3. Do not use ATF+2 or ATF+3 to top off vehicles that have ATF+4 fluid.

Benefits:
  • Better wear properties
  • Improved rust/corrosion prevention
  • Controls oxidation
  • Eliminates deposits
  • Controls friction
  • Retains anti-foaming properties
