    • Operate the system and determine if the concern is still present.

    Is the concern still present? 

    Yes  CHECK OASIS for any applicable TSBs. If a TSB exists for this concern, DISCONTINUE this test and FOLLOW TSB instructions. If no TSBs address this concern, INSTALL a new PCM. REFER to Electronic Engine Controls .
    No  The system is operating correctly at this time. The concern may have been caused by module connections. ADDRESS the root cause of any connector or pin issues.

  7. BI7 CHECK FOR CORRECT IPC OPERATION

    • Ignition OFF.
    • Disconnect and inspect the IPC connector.
    • Repair:
      • corrosion (install new connector or terminals - clean module pins)
      • damaged or bent pins - install new terminals/pins
      • pushed-out pins - install new pins as necessary
    • Reconnect the IPC connector. Make sure it seats and latches correctly.
    • Operate the system and determine if the concern is still present.

    Is the concern still present?
