    NOTE:
    • If the PCM is replaced with a new one without performing "Programmable Module Installation" procedure, the PCM will be set DTC P0602 and illuminates the MIL. This is because the configuration data is not programmed in the PCM.
  6. Retrieve DTCs with the WDS or equivalent, erase them, and verify that there are no DTCs present and the MIL is off.
    • If DTCs are still present, perform applicable DTC inspection.
