Diagnostic Test

WARNING: This page is about a different car, the 2013 Dodge Avenger and 2013 Chrysler 200. However, it is still accessible from the selected car via links, so may be relevant.
  1. CHECK FOR ACTIVE INTERNAL FAULTS, IGNITION FAULTS, AND BATTERY FAULTS IN THE OCCUPANT RESTRAINT CONTROLLER (ORC) 
    1. With the scan tool, read Occupant Restraint Controller (ORC) DTCs.

      Does the scan tool display any active DTCs relating to internal faults, ignition faults, or battery faults?

      Yes 

      No 

      • Go To  2
  2. VERIFY THAT DTC B1B8F-DRIVER SEAT TRACK POSITION SENSOR CIRCUIT OPEN IS ACTIVE 

    Does the scan tool display active: B1B8F-DRIVER SEAT TRACK POSITION SENSOR CIRCUIT OPEN?

    Yes 

    • Go To  3

    No 

  3. INSPECT DRIVER SEAT HARNESS WIRES AND CONNECTORS 
    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. Using the wiring diagram/schematic as a guide, inspect the Driver Seat Harness wiring and connectors. Look for chafed, pierced, pinched, or partially broken wires and broken, bent, pushed out, spread, corroded, or contaminated terminals.

      Are any of these conditions present?

      Yes 

      NOTE:

      Do not attempt to repair the Seat Harness. Replace the Seat Harness if any of these conditions exist

      • Replace the Driver Seat Harness in accordance with the Service Information.
      • Perform the AIRBAG SYSTEM VERIFICATION TEST. Refer to STANDARD PROCEDURE .

      No 

      • Go To  4
  4. VERIFY THAT THE DRIVER SEAT HARNESS IS ROUTED CORRECTLY 
    1. Verify that the Driver Seat Harness is routed correctly.

      Is the Driver Seat Harness routed correctly?

      Yes 

      • Go To  5

      No 

      • Reroute the Driver Seat Harness as necessary.
      • Perform the AIRBAG SYSTEM VERIFICATION TEST. Refer to STANDARD PROCEDURE .
  5. CHECK (R261) DRIVER SEAT POSITION SENSOR DATA CIRCUIT AND (R263) DRIVER SEAT POSITION SENSOR VOLTAGE CIRCUIT FOR AN OPEN

    1. Disconnect the ORC connectors.
    2. Connect the SRS Load Tool Adaptor (special tool #8443-25, 56 Way ACM Adapter) to the ORC C2 connector.
    3. Measure the resistance of the (R261) Driver Seat Position Sensor Data circuit between the SRS Load Tool Adaptor (special tool #8443-25, 56 Way ACM Adapter) cavity 24-7 and the Driver Seat Track Position Sensor connector cavity 1.

    4. Measure the resistance of the (R263) Driver Seat Position Sensor Voltage circuit between the SRS Load Tool Adaptor (special tool #8443-25, 56 Way ACM Adapter) cavity 24-8 and the Driver Seat Track Position Sensor connector cavity 2.

      Is the resistance of either circuit above 5.0 Ohms?

      Yes 

      NOTE:

      Do not attempt to repair the Seat Harness. Replace the Seat Harness if the condition inspecting or testing for is present in the Seat Harness.

      • Replace the Driver Seat Harness in accordance with the Service Information.
      • Perform the AIRBAG SYSTEM VERIFICATION TEST. Refer to STANDARD PROCEDURE .

      No 

      • Go To  6
  6. CHECK OPERATION OF THE DRIVER SEAT TRACK POSITION SENSOR 
    1. Replace the Driver Seat Track Position Sensor.
    2. Reconnect the vehicle body harness to the Seat Track Position Sensor.
    3. Remove any special tools or jumper wires and reconnect all previously disconnected components - except the Battery.
      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. Connect the scan tool to the Data Link Connector - use the most current software available.
    5. Use the scan tool and erase the stored codes in all airbag system modules.
    6. Turn the Ignition Off, and wait 15 seconds before turning the Ignition On.
    7. Wait one minute, and read active codes and if there are none present read the stored codes.

      Did the active Driver Seat Track Position Sensor DTC return?

      Yes 

      WARNING:

      If the Occupant Restraint Controller (ORC) is dropped at any time, it must be replaced. Failure to follow these instructions may result in possible serious or fatal injury.

      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.

      • Replace the Occupant Restraint Controller (ORC) in accordance with the service information.
      • Perform the AIRBAG SYSTEM VERIFICATION TEST. Refer to STANDARD PROCEDURE .

      No 

      • Repair is complete.
      • Perform the AIRBAG SYSTEM VERIFICATION TEST. Refer to STANDARD PROCEDURE .
