    No  GO to  AJ5.

  5. AJ5 CHECK THE BCM INPUT PIDs FROM THE IGNITION SWITCH

    • Using a scan tool, view the BCM PIDs.
    • Select and monitor the BCM ignition switch (IGN_ACC/RUN), (IGN_RUN/STRT) and (IGN_SW_STATE) PIDs while cycling the ignition switch through the ACC, OFF, RUN and START states.

    Do the BCM PIDs match the ignition switch position? 

    Yes  GO to  AJ6.
    No  REFER to Steering Column Switches to diagnose the ignition switch outputs to the BCM.

  6. AJ6 CHECK THE KEY-IN-IGNITION INPUT CIRCUIT FOR VOLTAGE AT THE BCM

    • Ignition OFF.
    • Remove the key from the ignition cylinder.
    • Measure the voltage  between:

    No  INSTALL a new ignition switch. REFER to Steering Column Switches .

  8. AJ8 CHECK FOR CORRECT BCM OPERATION

    • Disconnect and inspect all the BCM connectors.
    • Repair:
      • corrosion (install new connector or terminals - clean module pins)
      • damaged pins - install new terminals/pins
      • pushed-out pins - install new pins as necessary
    • Reconnect all the BCM connectors. Make sure they seat and latch correctly.
    • 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 BCM. REFER to Multifunction Electronic Modules .
    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.
