Operation CHARM: Car repair manuals for everyone.

Repair Procedure

This bulletin involves selectively erasing and reprogramming the Transmission Control Module (TCM) with new software (calibration changes).

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

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

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

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

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

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

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

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

8. 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.





9. Type the necessary information on the 1Authodzed Software Update Label" p/n 04669020 (Figure 1). Attach the label to the TCM and cover the label with the clear plastic overlay.
