PCM/ECM REPROGRAMMING - GAS

PCM/TCM FLASH REPROGRAMMING

This procedure is required when one or more of the following situations are true:

1. A Powertrain Control Module (PCM) has been replaced.
2. Diagnostic Trouble Code (DTC) P1602 - PCM Not Programmed is set.
3. An updated calibration or software release is available for either the PCM or TCM.

This procedure assumes that the wiTECH(TM) VCI Pod and StarMOBILE(R) devices are properly configured to the dealership network with either a wired or wireless connection. The wiTECH(TM) VCI Pod and StarMOBILE(R) must also be running the latest operating system and software release. For help on how to network the StarMOBILE(R), reference the appropriate Quick Start Networking Guide available on 'DealerCONNECT > Service > StarSCAN(R) and StarMOBILE(R) Tools > Online Documentation' or at www.dcctools.com, under the Download Center. For help on how to network the wiTECH(TM) VCI Pod, use the "Help" tab at the top of the wiTECH(TM) Diagnostic Application.

TECH TIPS and INFORMATION:

- The wiTECH(TM) Diagnostic Application is the preferred method for flashing any Chrysler vehicle ECU. Training aids, including videos, are included under the "Help" tab in the wiTECH(TM) Diagnostic Application.
- To use the StarMOBILE(R) in Pass-Through Mode requires that the StarMOBILE(R) is connected to the dealerships network via a wired or wireless connection. For more information on how to use the StarMOBILE in Pass-Through Mode, see the StarMOBILE(R) training tutorials available on 'DealerCONNECT > Service > StarSCAN(R) and StarMOBILE(R) Tools > Training Aids' link or at www.dcctools.com, under the 'Training Aids' link.
- If the flash process is interrupted or aborted, the flash should be restarted.
- Due to the PCM/TCM programming procedure, a DTC may be set in other ECUs within the vehicle. Some DTCs may cause the MIL to illuminate. From the "Home" screen select "System View". Then select "All DTCs". Press "Clear All Stored DTCs" if there are any DTCs shown on the list.
- When replacing a GPEC PCM for a vehicle that is equipped with a CVT, it is extremely important that the PCM and TCM both have the latest software calibrations.
- Do not allow the battery charger to time out or the charging rate to climb above 13.5 volts during the flash process.
- The StarMOBILE(R) diagnostic tools fully support Internet connectivity and must be configured for the dealership network. For help on setting up the StarMOBILE(R) for the dealership network, refer to the StarMOBILE(R) Quick Start Networking Guide available on 'DealerCONNECT > Service > StarSCAN(R) and StarMOBILE(R) Tools > Online Documentation' or at www.dcctools.com, under the download center.
- The operating software in the wiTECH(TM) VCI Pod, wiTECH(TM) Diagnostic Application, and StarMOBILE(R) must be programmed with the latest software release. The software level is visible in the blue header at the top of the wiTECH(TM) Diagnostic Application and StarMOBILE(R) Desktop Client screens. For instructions on how to update the StarMOBILE(R), refer to the StarMOBILE(R) Update guide available on 'DealerCONNECT > Service > StarSCAN(R) and StarMOBILE(R) Tools > Online Documentation' or at www.dcctools.com, under the Download Center. For instructions on how to update the wiTECH(TM) VCI Pod or wiTECH(TM) Diagnostic Application, use the "Help" tab at the top of the wiTECH(TM) Diagnostic Application.
