Diagnostic Test

  1. 1) CHECK FOR ACTIVE INTERNAL FAULTS, IGNITION FAULTS, AND BATTERY FAULTS IN THE OCCUPANT RESTRAINT CONTROLLER (ORC) 

    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 

    1. Diagnose and repair the DTCs. Refer to DIAGNOSTIC CODE INDEX  table for a complete list of symptoms.

    No 

    1. Go to  2).
  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 

    1. Go to  3).

    No 

    1. Go to  8).
  3. 3) INSPECT DRIVER SEAT HARNESS WIRES AND CONNECTORS 
    WARNING: To avoid serious or fatal injury, turn the ignition off, disconnect the battery and wait two minutes before proceeding.

    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
    1. Replace the Driver Seat Harness in accordance with the Service Information.
    2. Perform *ORC VERIFICATION TEST - VER 1 .

    No 

    1. Go to  4).
  4. 4) VERIFY THAT DRIVER SEAT HARNESS IS ROUTED CORRECTLY 

    Verify that the Driver Seat Harness is routed correctly.

    Is the Driver Seat Harness routed correctly? 

    Yes 

    1. Go to  5).

    No 

    1. Reroute the Driver Seat Harness as necessary.
    2. Perform *ORC VERIFICATION TEST - VER 1 .
  5. 5) CHECK FOR DTC B1B8F-DRIVER SEAT TRACK POSITION SENSOR CIRCUIT OPEN WITH DRIVER SEAT TRACK POSITION SENSOR DISCONNECTED 
    WARNING: To avoid serious or fatal injury, turn the ignition off, disconnect the battery and wait two minutes before proceeding.

    Disconnect the Driver Seat Track Position Sensor connector.

    WARNING: To avoid serious or fatal injury, turn the ignition on, then reconnect the battery.

    Wait two minutes, and then with the scan tool, read ORC DTCs.

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

    Yes 

    1. Go to  6).

    No 

    WARNING: To avoid serious or fatal injury, turn the ignition off, disconnect the battery and wait two minutes before proceeding.
    1. Replace the Driver Seat Track Position Sensor in accordance with the service information.
    2. Perform *ORC VERIFICATION TEST - VER 1 .
  6. 6) CHECK (R261) DRIVER SEAT POSITION SENSOR DATA CIRCUIT AND (R263) DRIVER SEAT POSITION SENSOR VOLTAGE CIRCUIT FOR A SHORT TO VOLTAGE

    WARNING: To avoid serious or fatal injury, turn the ignition off, disconnect the battery and wait two minutes before proceeding.

    Measure the resistance between the (R261) Driver Seat Position Sensor Data circuit and the (R263) Driver Seat Position Sensor Voltage circuit in the Driver Seat Track Position Sensor connector.

    Is the resistance below 10k ohms? 

    Yes 

    NOTE: Do not attempt to repair the Seat Harness. Replace the Seat Harness if any of these conditions exist
    1. Replace the Driver Seat Harness in accordance with the service information.
    2. Perform *ORC VERIFICATION TEST - VER 1 .

    No 

    1. Replace the ORC in accordance with the Service information.
    2. Perform *ORC VERIFICATION TEST - VER 1 .
  8. 8) TEST FOR AN INTERMITTENT CONDITION 

    With the scan tool, record and erase all DTC's from the ORC.

    If any ACTIVE codes are present they must be resolved before diagnosing any stored codes.

    WARNING: To avoid serious or fatal injury, turn the ignition off, disconnect the battery and wait two minutes before proceeding.

    Using the wiring diagram/schematic as a guide, inspect the wiring and connectors.

    Look for chafed, pierced, pinched, or partially broken wires and broken, bent, pushed out, spread, corroded, or contaminated terminals.

    The following additional checks may assist you in identifying a possible intermittent problem.
