Diagnostic Test

WARNING: This page is about a different car, the 2015 Fiat 500. However, it is still accessible from the selected car via links, so may be relevant.
  1. VERIFY THAT DTC B0111-64-DRIVER REMOTE ACCELERATION SENSOR (SATELLITE) - SIGNAL PLAUSIBILITY FAILURE IS ACTIVE 
    WARNING:

    Turn the ignition off disconnect the 12-volt battery and wait two minutes before proceeding. Failure to follow these instructions may result in possible serious or fatal injury.

    NOTE:

    Using the wiring diagram/schematic as a guide check all related splices and connectors for signs of water intrusion, corrosion, pushed out or bent terminals, and correct pin tension.

    NOTE:

    If after the harness inspection it appears the impact sensor connector is only seated halfway. Reseat the harness connector into the impact sensor and lock the tab.

    WARNING:

    Turn the ignition on, then reconnect the 12-volt battery and wait two minutes before proceeding. Failure to follow these instructions may result in possible serious or fatal injury.

    NOTE:

    Make sure the battery is fully charged.

    1. Turn the ignition on.
    2. With the scan tool, read ORC DTCs.

      Does the scan tool display active: B0111-64-DRIVER REMOTE ACCELERATION SENSOR (SATELLITE) - SIGNAL PLAUSIBILITY FAILURE - DTC?

      Yes 

      • Go To  2

      No 

  2. CHECK THE (R131) AND (R151) LEFT SIDE IMPACT SENSOR 1 CIRCUITS FOR A SHORT TO BATTERY

    WARNING:

    Turn the ignition off disconnect the 12-volt battery and wait two minutes before proceeding. Failure to follow these instructions may result in possible serious or fatal injury.

    1. Disconnect the Left Side Impact Sensor 1 harness connector.
    2. Disconnect the ORC harness connectors.
      NOTE:

      Check connectors - Clean and repair as necessary.

      NOTE:

      After disconnecting the ORC module and the ORC module body harness connector, check the ORC module body harness connector shorting bar pin location. The shorting bar pin location should be down and not visible through the larger center holes of the ORC module body harness connector.

    3. Connect the (special tool #8443-25, 56 Way ACM Adapter) to the ORC C2 harness connector.
      WARNING:

      Turn the ignition on, then reconnect the 12-volt battery and wait two minutes before proceeding. Failure to follow these instructions may result in possible serious or fatal injury.

    4. Measure the voltage of the (R131) Left Side Impact Sensor 1 Signal circuit and the (R151) Sensor 1 Ground circuit at the Left Side Impact Sensor 1 harness connector.

      Is there any voltage present?

      Yes 

      • Repair the (R131) and (R151) Left Side Impact Sensor 1 circuits for a short to battery.
      • Perform the RESTRAINTS SYSTEM VERIFICATION TEST. Refer to RESTRAINTS SYSTEM VERIFICATION TEST .

      No 

      • Go To  3
  3. CHECK THE (R131) AND (R151) LEFT SIDE IMPACT SENSOR 1 CIRCUITS FOR A SHORT TO GROUND

    WARNING:

    Turn the ignition on, then reconnect the battery and wait two minutes before proceeding. Failure to follow these instructions may result in possible serious or fatal injury.

    1. Measure the resistance between ground and the (R131) Left Side Impact Sensor 1 Signal circuit at the Left Side Impact Sensor 1 harness connector.
    2. Measure the resistance between ground and the (R151) Left Side Impact Sensor 1 Ground circuit at the Left Side Impact Sensor 1 harness connector.

      Is the resistance below 100K Ohms on either circuit?

      Yes 

      • Repair the (R131) and (R151) Left Side Impact Sensor 1 Signal and Ground circuit for a short to ground.
      • Perform the RESTRAINTS SYSTEM VERIFICATION TEST. Refer to RESTRAINTS SYSTEM VERIFICATION TEST .

      No 

      • Go To  4
  4. CHECK THE (R131) AND (R151) LEFT SIDE IMPACT SENSOR 1 CIRCUITS FOR A SHORT TOGETHER 
    Fig 4: Checking Left Side Impact Sensor 1 Circuits For Short Together
    GC0138245Courtesy of CHRYSLER GROUP, LLC
    1. Measure the resistance between the (R131) Left Side Impact Sensor 1 Signal circuit and the (R151) Sensor 1 Ground circuit at the Left Side Impact Sensor 1 harness connector.

      Is the resistance below 100K Ohms?

      Yes 

      • Repair the (R131) and (R151) Left Side Impact Sensor 1 circuits shorted together.
      • Perform the RESTRAINTS SYSTEM VERIFICATION TEST. Refer to RESTRAINTS SYSTEM VERIFICATION TEST .

      No
