No Communication Between the Integrated Diagnostic System (IDS) and the Vehicle

  1. Refer to: «HEALTH AND SAFETY PRECAUTIONS»(ref-515929-S17418754162012120400000) .
  2. Establish a scan tool session.
  3. Turn ignition to RUN.
  4. 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.
  5. If an IDS session cannot be established with the vehicle, IDS may state "No communication can be established with the Powertrain Control Module (PCM)."
  6. Choose "NO" when the scan tool prompts whether or not to retry communication.
  7. Enter 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.
  8. If the scan tool cannot communicate with the vehicle after manually entering the PCM part number, diagnose the PCM does not respond to the scan tool. Refer to: «Communications Network»(ref-515972-S05756060702012120400000) .
