Repair Procedure

This repair involves testing the manifold tuning valve solenoid, replacing it if necessary and selectively erasing and reprogramming the Powertrain Control Module (PCM) with new software (calibration changes) for all conditions listed.

1. Connect the MDS (Mopar Diagnostic System) and DRB III (Scan Tool) to the vehicle and power them up.

2. Select the engine controller menu and select actuator tests.

3. Select MTV SOLENOID and start the manual actuation of the valve.

4. Listen for valve actuation.

5. If the valve actuates, proceed with the remaining flash portion of this bulletin. If the solenoid valve does not operate, replace it before proceeding with the flash portion of the bulletin.

6. Go back to the Main Menu of the Diagnostic screen.

7. Use the arrow keys and select # 2 MDS DIAGNOSTICS on the DRB III MAIN MENU Screen.

8. Use the arrow keys and select DIAGNOSTIC MENU on the MDS, then press NEXT MENU.

9. Use the arrow keys and select VEHICLE CONTROLLER PROGRAMMING on the MDS, then press NEXT MENU.

10. Use the arrow keys and select PROGRAMMING OF ALL OTHER CONTROLLERS USING MDS & DRB III on the MDS, then press NEXT MENU.

11. Follow the steps presented on the MDS and DRB III which will allow the DRB III to obtain the current part number of the PCM.

12. The MDS will display the part number of the PCM on the vehicle and the appropriate replacement part number, then press NEXT MENU to begin programming.

If the PCM on the vehicle has already been updated or programmed, a NO UPDATES AVAILABLE message will be displayed. Check the part number of the PCM on the vehicle and compare it to the part number displayed. If the PCM has already been updated, then another condition exists that will require further diagnosis and repair.

13. The MDS and DRB III will prompt for any operator action needed during the remainder of the programming process.

NOTE:
THE FOLLOWING STEPS ARE REQUIRED BY LAW.
