PCM/TCM Reprogramming
PCM / TCM PROGRAMMING
PCM / TCM FLASH PROGRAMING
This procedure will need to be done when one or more of the following situations are true:
1. A vehicle's Powertrain Control Module (PCM) has been replaced.
2. A diagnostic trouble code (DTC) is set P1602 - PCM Not Programmed.
3. An updated calibration or software release is available for either the PCM or TCM ECUs.
This procedure assumes that the wiTECH(TM) Vehicle Connection Interface (VCI) pod, StarSCAN(R) and StarMOBILE(R) devices are configured to
your dealership's network with either a wired or wireless connection. The wiTECH(TM) VCI pod, StarSCAN(R) and StarMOBILE(R) must also be
running at the latest operating system and software release level. For more help on how to network your StarSCAN(R) or StarMOBILE(R) reference the
StarSCAN(R) / StarMOBILE(R) Quick Start Networking Guide available on 'DealerCONNECT > Service > StarSCAN(R) and StarMOBILE(R) Tools
> Online Documentation', under the Download Center. For the wiTECH(TM) VCI pod use the "HELP" tab in the wiTECH(TM) Diagnostic Application.
