    Possible Sources 

    • SIMA

  2. G1 CONFIRM THE DTC (DIAGNOSTIC TROUBLE CODE) RESETS

    • Check vehicle service history for recent service actions related to the SIMA.

    • Connect the diagnostic tool.

    • Ignition ON.

    • Using the diagnostic scan tool, clear the DTC.

    • Wait 10 seconds.

    • Using the diagnostic scan tool, perform the SIMA self-test.

    Are any DTCs still present? 

    Yes  GO to G2 
    No  The system is operating correctly at this time. The DTC may have been falsely set by the SIMA causing the signal to momentarily stop and set the DTC.
  3. G2 CHECK FOR CORRECT SIMA (SWITCH INPUT MODULE A) OPERATION

    • Ignition OFF.

    • Disconnect and inspect all SIMA connectors.

    • 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 SIMA 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 service articles: TSB, GSB, SSM or FSA. If a service article exists for this concern, DISCONTINUE this test and FOLLOW the service article instructions. If no service articles address this concern, INSTALL a new SIMA. REFER to: Switch Input Module A (SIMA) .
    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.
