Front Suspension

02-003-084500/5500 Front and/or rear shock absorber noise.

The customer may experience a clunking-like sound when traveling over small inputs (bumps and dips) in the road. This clunk-like sound is sometimes described as being similar to the sound that “loose lumber” may make when loose boards strike each other. This condition is more noticeable during cold ambient conditions below 40°F and at lower vehicle speeds when background noise is less. The sound may come from the front and/or rear shock absorbers.

This condition is due to internal components within the vehicle shock absorber and the bulletin describes the replacement procedure.
08-007-08AllEngine does not crank or start due to electronic lockup of the remote key module.
This bulletin applies to vehicles built on or before May 05, 2008. The customer may experience a no engine crank and a no engine start condition. Also, the remote keyless entry system will not operate. This condition may be due to an electrostatic discharge from the ignition key into the wireless control module (WCM), causing the WCM to electronically lockup. This condition is corrected by the replacement of the WCM (also known as the Sentry Key Remote Entry Module).

Exhaust

11-002-07 2500/3500 Inspection and test procedures for the 6.7-liter diesel particulate filter (DPF).

This bulletin applies to vehicle equipped with a Cummins 6.7-liter engines (sales code ETF). The customer may experience a malfunction indicator lamp (MIL) illumination, warning chime, and an overhead electronic vehicle information center (EVIC) message that states “Catalyst Full Service Required.” Investigation may reveal that the MIL illumination is due to one or more of the following diagnostic trouble codes (DTCs):
P1451 – Diesel Particulate Filter System Performance.
P2463 – Diesel Particulate Filter – Soot Accumulation.
P242F – Diesel Particulate Filter Restriction – Ash Accumulation.

The balance of the 10-page bulletin describes the inspection, test, repair, or replacement of the DPF based on the severity of the accumulation in the DPF.11-001-082500/3500Cleaning the turbocharger on the Cummins 6.7-liter engine.
This 17-page bulletin describes the process of cleaning the turbocharger using Cummins Engine Update Kit 10138-UPD to address excess soot accumulation. The procedure cleans the internal components on the exhaust side of the turbocharger.

The bulletin goes hand-in-hand with TSBs 11-005-08 and 11-002-07 for detailed turbocharger, engine and exhaust aftertreatment system repair procedures.11-002-082500/3500Inspections and test for the turbocharger on the Cummins 6.7-liter engine.
The customer may experience a malfunction indicator lamp (MIL) illumination due to diagnostic trouble code (DTC): P2262 – Turbocharger Boost Pressure Not Detected – Mechanical.

If further codes of P1451, P2463 or P242F are present the technician is referred to the repair procedure listed in TSB 11-002-07. If the codes are not present the repair and cleaning procedures in this 8-page bulletin and TSB 11-001-08 are to be performed.


Vehicle Performance

18-013-08 All Engine system and exhaust aftertreatment system enhancements.

This bulletin applies to vehicles equipped with a Cummins 6.7-liter engine (sales code ETJ) built on or before February 14, 2008. This bulletin discusses the G30 recall and the many drivability issues that are addressed and covered in the G30 recall software update. (See http://www.cumminsownerz.com/f13/dod...g30-recall-53/ )

Transmission


21-003-07 All Automatic transmission diagnostic tear down procedure.
This bulletin provides a procedure to determine repair versus replacement of an automatic transmission assembly. Follow the proper repair procedure based on the transmission type. This procedure is to be used after the transmission has been removed from the vehicle.

This bulletin supersedes technical service bulletin 21-008-06, dated 04/08/06.21-014-07AllAutomatic transmission fl uid usage ATF+4 (Type MS9602).




This bulletin supersedes technical service bulletin 21-010-06, dated 4/16/06. ATF+4, type 9602, is being used as factory fi ll for Chrysler Group automatic transmissions. ATF+4 is recommended for all vehicles equipped with Chrysler Group automatic transmissions except for those noted: Sprinter transmissions, Crossfi re transmissions, MK/PM vehicles equipped with Continuously Variable Transmission (CVT) all vehicles equipped with a A568RC transmission (sales code DG3), all vehicles with a Gentrag MP56 (sales code DG5), and Grand Cherokee’s with the diesel engine option. ATF+4 is backward compatible with ATF+3, ATF+2, and ATF+. Additionally, ATF+4 can be used to top off vehicles that used ATF+3, ATF+2, or ATF+. Benefits:

• Better anti-wear properties
• Improved rust/corrosion prevention
• Controls oxidation
• Eliminates deposits
• Controls friction
• Retains anti-foaming properties
• Superior properties for low temperature operation.

Mopar ATF+4 has exceptional durability. However, the red dye used in ATF+4 is not permanent; as the fl uid ages it may become darker or appear brown in color. ATF+4 also has a unique odor that may change with age. With ATF+4 fl uid, color and odor are no longer indicators of fl uid condition and do not necessarily support a fl uid change.21-019-072500/350068RFE transmission – harsh coastdown shift and/or harsh 2-3 upshift.
This bulletin applies to vehicles equipped with a 68RFE automatic transmission (sale code DG7) built on or before November 6, 2007. The customer may experience a harsh downshift from the transmission when coming to a stop. When a vehicle stop is initiated from 4th gear (around 25mph), the harsh downshift condition will usually occur as the vehicle decelerates to a speed of about 10mph. If the transmission is in 2nd, 3rd, 5th, or 6th gear, when the stop is initiated, the condition will not be present. This may cause the condition to appear to be intermittent to the customer. Because the harsh downshift may occur below 10mph the customer may believe that they are experiencing a harsh 2-1 downshift.

Some customers may also experience a harsh 2-3 upshift during normal acceleration. This symptom is less common than the harsh coastdown shift.

This bulletin involves selectively erasing and reprogramming the transmission control module (TCM) with new software.

Wheels & Tires


22-002-072500 Tire pressure monitor system (TPMS) “Light Load” reset switch and tire rotation caution.

This information only bulletin provides information for new vehicle preparation, setting tire pressures, rotating tires and the right load switch on vehicles with the tire pressure monitoring system installed.

Body

23-035-07 DC/DM/DR/DH/D1Exterior Lamp - Lens fogging.
Some customers may report that vehicle exterior lamp assemblies are fogged with a light layer of condensation on the inside of the lenses. This may be reported after the lamps have been turned on and brought up to operating temperature, turned off, and then rapidly cooled by cold water (such as rain, or the water from a car wash). Lens fogging can also occur under certain atmospheric conditions after a vehicle has been parked outside overnight (i.e., a warm humid day followed by clear cool night). This will usually clear as atmospheric conditions change to allow the condensation to change back into a vapor. Turning the lamps on will usually accelerate this process.

A lamp that has a large number of water droplets visible on most internal surfaces indicates a problem with the lamp sealing that has allowed water to enter the lamp. In this instance, the customer is likely to report that moisture in the lamp is always present and never disappears. A lamp that exhibits internal moisture permanently should be replaced.

This bulletin supersedes technical service bulletin 23-041-06, dated September 27, 2006. 23-046-07DR/DH/D1/DCRepair of etched paint.
This bulletin involves evaluating the paint condition on al horizontal panels for etching. f the problem exists, the bulletin describes the proper repair procedure using sanding/buffi ng techniques or spot paint refi nishing.23-017-08DR/DH/D1Tailgate retaining cables appear to be of unequal lengths.
This bulletin applies to vehicles built on or before May 7, 2008. One of the two side tailgate check cables may not be properly tensioned. This condition may cause an appearance that the tailgate cables are of unequal lengths. The repair procedure involves setting the loose/longer in appearance cable firmly into its seat.
