General Procedure

  1. Establish a scan tool session.
  2. Turn ignition to RUN.
    NOTE: For Intelligent Access (IA) vehicles, REFER to PUSH-BUTTON START - WITH INTELLIGENT ACCESS (IA) , RUN.
    If the RFA module has been replaced, it may not be possible to put the ignition in RUN. The RFA module can communicate with a scan tool with the ignition in the OFF state.
  3. The scan tool first attempts to communicate with the PCM. After establishing communication with the PCM, the scan tool then attempts to communicate with all other modules on the vehicle.
  4. If an IDS session cannot be established with the vehicle, IDS may state "No communication can be established with the PCM."
  5. Choose "NO" when the scan tool prompts whether or not to retry communication.
  6. Enter either a PCM part number, tear tag or calibration number to identify the vehicle and start a session. The PCM part number and 4-character tear tag number are printed on the PCM label. If the PCM part number cannot be found, a base part number search on the HVBOM application (under the OASIS  tab on the technician service publication website) retrieves the PCM part number.
  7. REFER to Diagnostic Routine A: The Powertrain Control Module (PCM) Does Not Respond To The Scan Tool .
