Remedy Available  

 

NOTE:  This recall applies only to the above trucks equipped with a 6.7L Cummins diesel engine (Sales Code ETL or ETN or ETM).

NOTE:  Some vehicles above may have been identified as not involved in this recall and therefore have been excluded from this recall.

IMPORTANT:  Some of the involved vehicles may be in dealer new vehicle inventory.  Federal law requires you to complete this recall service on these vehicles before retail delivery.  Dealers should also consider this requirement to apply to used vehicle inventory and should perform this recall on vehicles in for service.  Involved vehicles can be determined by using the VIP inquiry process.

 

Subject

The diesel engine on about 560 of the above vehicles may have been manufactured with fuel lines with incorrectly formed end fittings that may not properly seal to other fuel system components. Fuel lines that do not properly seal may lead to a fuel leak in the engine compartment. A fuel leak in the engine compartment may lead to a vehicle fire, which may increase risk of injury to occupants and persons outside the vehicle, as well as property damage.

 

Repair

Cummins will send a representative to inspect the fuel line date codes. If any of the fuel line date codes are found to be within the suspect build population, the suspect line(s) will be replaced.

 

Alternate Transportation

Dealers should attempt to minimize customer inconvenience by placing the owner in a loaner vehicle if inspection determines that fuel tube replacement is required and the vehicle must be held overnight.

 

Parts Information

Do NOT place an order, parts will be manually allocated by MOPAR.

 

Parts Return

No parts return required for this campaign.

 

Special Tools

The following special tools are required to perform this repair:

 

Service Procedure

Do NOT perform any of these service procedures without prior authorization. A Cummins representative will be dispatched to your dealership to inspect the fuel tube date codes. If any of the fuel tube date codes are found to be within the suspect build population, the Cummins representative will identify which suspect tubes(s) must be replaced. Replacement of any fuel tube without prior authorization will result in forfeit of warranty reimbursement.

 

A.  Tube Removal Preparation Procedures 

CAUTION: Cleanliness cannot be over emphasized when handling or replacing diesel fuel system components. This especially includes the fuel injectors, high-pressure fuel tubes and fuel injection pump. Very tight tolerances are used with these parts. Dirt contamination could cause rapid part wear and possible plugging of fuel injector nozzle tip holes. This in turn could lead to possible engine misfire. Always wash/clean any fuel system component thoroughly before disassembly and then air dry. Cap or cover any open part after disassembly. Before assembly, examine each part for dirt, grease or other contaminants and clean if necessary.

5. Connect the IBS wire harness connector (Figure 1).

6. Be sure there is fuel in the fuel tank.

7. Turn ignition switch to the RUN position. This will operate fuel transfer pump for a minimum of 30 seconds.

8. Turn the ignition switch to the OFF position, and leave it off for at least 5 seconds.

 

NOTE: A certain amount of air becomes trapped in the fuel system when fuel system components on the supply and/or high-pressure side are serviced or replaced. Fuel system priming is accomplished using the electric fuel transfer (lift) pump.

 

The fuel transfer (lift) pump is self-priming: When the ignition switch is turned to the run position (without cranking engine), the pump operates for a minimum of 30 second. In cold temperatures, the lift pump operates for up to 35 seconds. Two priming cycles (each with a duration of 30 seconds) must be performed any time the fuel system is serviced

 

9. Turn the ignition switch to the RUN position. This will complete an additional priming cycle and operate the fuel transfer pump for a minimum of 30 seconds.

10. Start the engine. If the engine does not start after 25 seconds, turn the ignition switch to the OFF position, and leave it off for at least 5 seconds. Repeat the previous step until the engine starts. When engine does start, allow the engine to idle for a minimum of 30 seconds. The engine may run erratically and be noisy for a few minutes. This is a normal condition.

11. Fuel system priming is now completed.

 

CAUTION: Do not engage the starter motor for more than 30 seconds at a time. Allow two minutes between cranking intervals.

 

WARNING: The fuel injection pump supplies extremely high fuel pressure to each individual injector through the high-pressure tubes. Fuel under this amount of pressure can penetrate the skin and cause personal injury. Wear safety goggles and adequate protective clothing. Do not loosen fuel fittings while engine is running.

 

WARNING: Engine may start while cranking starter motor

 

12. Start engine and check for leaks.

13. Validation Run Fuel System Leak Test for Diesel ECM Controller Modules (Fuel Pressure Override Test)

14. Install a battery charger and verify that the charging rate provides 13.2 to 13.5 volts. Do not allow the charger to time out during the flash process.  Set the battery charger timer (if so equipped) to continuous charge.

 

NOTE:  Use an accurate stand-alone voltmeter.  The battery charger volt meter may not be sufficiently accurate.  If voltage reading is too high, apply an electrical load by activating the park or headlamps and/or HVAC blower motor to lower the voltage.
