Updates don't need to be done the high idle already exist in the ECM and you must turn it ON...Repair Procedure: 1. Log onto the MDS2 (Mopar Diagnostic System). 2. Connect the MDS2 and DRBIII to the vehicle and switch the ignition key to"ON". NOTE: AUTO CONNECTION WILL OCCUR ONCE THE DRB III, MDS2, AND VEHICLE ESTABLISH COMMUNICATION. THE "CANNOT READ VIN FROM DRB III" MESSAGE (ON THE MDS2) WILL BE REPLACED BY THE VEHICLE VIN. PRESS THE "OK" BUTTON ON THE MDS2 TO REQUEST A L4DS2 SESSION FOR THE VEHICLE VIN INDICATED. PRESS THE "OK"BUTTON WHEN ASKED TO BEGIN SESSION. 3. Push the FLASH tab on the MDS2. 4. Select READ PART NUMBERS FROM VEHICLE and click SHOW UPDATES on the MDS2. NOTE: A MESSAGE MAY APPEAR (AFTER STEP 3 OR 4) THAT INDICATES NO UPDATES ARE AVAILABLE. IF THIS OCCURS, MAKE SURE YOUR DIAGNOSTIC EQUIPMENT IS OPERATING AT THE LATEST SOFTWARE LEVEL AS LISTED EARLIER IN THIS BULLETIN. IF THE LATEST SOFTWARE IS INSTALLED, AND NO UPDATES ARE AVAILABLE ANOTHER VEHICLE CONDITION EXISTS THAT WILL REQUIRE FURTHER INVESTIGATION. 5. Select the new software part number with the light pen and click UPDATE CONTROLLER SOFTWARE. 6. The MDS2 and DRB III will prompt for any operator action needed during the remainder of the reprogramming process. NOTE: DUE TO THE PCM REPROGRAMMING PROCEDURE, A DTC MAY BE SET IN OTHER MODULES (EATX, BCM, MIC, SKIM, ETC.) WITHIN THE VEHICLE, IF SO EQUIPPED. SOME DTC'S MAY CAUSE THE MIL TO ILLUMINATE. ALL DTC'S RELATE TO A LOSS OF COMMUNICATIONS WITH THE MODULE THAT IS BEING REPROGRAMMED. CHECK ALL MODULES, RECORD THE FAULTS, AND ERASE THESE FAULTS PRIOR TO RETURNING THE VEHICLE TO THE CUSTOMER. ERASE ANY FAULTS IN THE PCM ONLY AFTER ALL OTHER MODULES HAVE HAD THEIR FAULTS ERASED. NOTE: ONCE THE VEHICLE HAS BEEN REPROGRAMMED TO THE PROPER SOFTWARE LEVEL, YOU MUST USE THE DRB III TO ENABLE THE 3 CYLINDER IDLE FEATURE. TO DO SO FOLLOW THE INSTRUCTIONS BELOW. 7. Connect the DRB III to the vehicle without connecting to MDS2 and follow the menu structures it appears below. 8. MAIN MENU - 1998 - 2002 DIAGNOSTICS 9. 1998 - 2002 DIAGNOSTICS - ALL (EXCEPT BELOW) 10. SELECT SYSTEM - 1 ENGINE 11. CONTROLLER TYPE - 1 CUMMINS (ECM/ENGINE) 12. SELECT FUNCTION - 1 MISCELLANEOUS (Misc. is on second page) 13. 3.3 CYLINDER IDLE - Follow the instructions The DRB III will indicate whether the feature is enabled or disabled. 14. Push 1 to Enable, 2 to Disable. 15. You are instructed to cycle the ignition to complete the repair. 16. Press Page Back to Exit. NOTE: THE FOLLOWING STEPS ARE REQUIRED BY LAW. 17. Type the necessary information on the "Authorized Software Update Label" p/n 04669020 (Fig. 1). Attach the label to the PCM and cover the label with the clear plastic overlay.
