Diagnostic Test

  1. IDENTIFYING VEHICLE EQUIPMENT 
    NOTE: Ensure the battery is fully charged.
    1. Turn the ignition on.
    2. With the scan tool, read ORC active DTCs.

      Does the scan tool display active DTC: B1B8D-DRIVER SEAT TRACK POSITION SENSOR CIRCUIT LOW?

      Yes 

      • Go to step  2

      No 

      • Go to step  7
  2. 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 step  3
  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 

      No 

      • Go to step  4
  4. VERIFY THAT 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 step  5

      No 

  5. CHECK (R261) DRIVER SEAT POSITION SENSOR DATA CIRCUIT AND (R263) DRIVER SEAT POSITION SENSOR VOLTAGE CIRCUIT FOR A SHORT TO GROUND

    1. Measure the resistance between ground and the (R261) Driver Seat Position Sensor Data circuit cavity 1.
    2. Measure the resistance between ground and the (R263) Driver Seat Position Sensor Voltage circuit cavity 2.

      Is the resistance below 10k ohms on either circuit?

      Yes 

      No 

      • Go to step  6
  6. 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 8443-24 ORC adaptor to the ORC C1 connector.
    3. Measure the resistance of the (R261) Driver Seat Position Sensor Data circuit between the ORC-C1 connector cavity C1-13 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 ORC-C1 connector cavity C1-17 and the Driver Seat Track Position Sensor connector cavity 2.

      Is the resistance of either circuit above 5.0 ohms?

      Yes 

      No 

        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.
        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.
      • Replace the Occupant Restraint Controller (ORC) in accordance with the service information.
      • Perform the AIRBAG SYSTEM VERIFICATION TEST. See DTC-Based Diagnostics/CONTROLLER, Occupant Restraint (ORC) - Standard Procedure .
  7. TEST FOR AN INTERMITTENT CONDITION 
    1. With the scan tool, record and erase all DTC's from the ORC.
    2. If any ACTIVE codes are present they must be resolved before diagnosing any stored codes.
      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.
    3. Using the wiring diagram/schematic as a guide, inspect the wiring and connectors.
    4. Look for chafed, pierced, pinched, or partially broken wires and broken, bent, pushed out, spread, corroded, or contaminated terminals.
    5. The following additional checks may assist you in identifying a possible intermittent problem.
    6. Reconnect any disconnected components and harness connector.
      WARNING: Turn the ignition on, then reconnect the 12-volt battery. Wait two minutes before proceeding. Failure to follow these instructions may result in possible serious or fatal injury.
    7. With the scan tool monitor active codes as you work through the following steps.
      WARNING: Maintain a safe distance from all airbags while performing the following steps. Failure to follow these instructions may result in possible serious or fatal injury.
    8. Wiggle the wiring harness and connectors of the related airbag circuit or component.
    9. If only stored codes return continue the test until the problem area has been isolated.
    10. In the previous steps you have attempted to recreate the conditions responsible for setting active DTC in question.

      Are any ACTIVE DTCs present?

      Yes 

      No 

      • No problem found at this time. Erase all codes before returning vehicle to customer.
