Diagnostic Test

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 

   • Refer to OCCUPANT RESTRAINT CONTROLLER (ORC) - DIAGNOSTIC CODE INDEX - 500 - EXCEPT ELECTRIC and perform the appropriate diagnostic procedure.

   No 

   • Go To  2

Does the scan tool display active: B0129-13-FRONT DRIVER SEAT TRACK POSITION SENSOR - CIRCUIT OPEN?

Yes 

• Go To  3

No 

• Go To  8

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 RESTRAINTS SYSTEM VERIFICATION TEST. Refer to RESTRAINTS SYSTEM VERIFICATION TEST .

   No 

   • Go To  4

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 RESTRAINTS SYSTEM VERIFICATION TEST. Refer to RESTRAINTS SYSTEM VERIFICATION TEST .

1. Disconnect the Driver Seat Track Position Sensor 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.

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

   Does the scan tool display: B0129-13-FRONT DRIVER SEAT TRACK POSITION SENSOR - CIRCUIT OPEN?

   Yes 

   • Go To  6

   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.

   • Replace the Driver Seat Track Position Sensor in accordance with the service information. Refer to SENSOR, SEAT TRACK POSITION, REMOVAL .
   • Perform the RESTRAINTS SYSTEM VERIFICATION TEST. Refer to RESTRAINTS SYSTEM VERIFICATION TEST .

1. Disconnect the ORC C1 harness connector.
   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 pin to shorting bar location. The pins location should be down and not visible through the larger center holes of the ORC module body 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.

2. Connect the SRS Load Tool (special tool #8443-25, 56 Way ACM Adapter) to the ORC harness connector.
3. Measure the voltage of the (R261) Driver Seat Position Sensor Data circuit between the Driver Seat Track Position Sensor harness connector and ground.
4. Measure the voltage of the (R263) Driver Seat Position Sensor Voltage circuit between the Driver Seat Track Position Sensor harness connector and ground.

   Is the voltage above 0.2 of a volt on either circuit?

   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.

   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 Driver Seat Harness in accordance with the Service Information.
   • Perform the RESTRAINTS SYSTEM VERIFICATION TEST. Refer to RESTRAINTS SYSTEM VERIFICATION TEST .

   No 

   • Go To  7

1. 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 harness 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

   • Replace the Driver Seat Harness in accordance with the service information.
   • Perform the RESTRAINTS SYSTEM VERIFICATION TEST. Refer to RESTRAINTS SYSTEM VERIFICATION TEST .

   No 

   • Replace the ORC in accordance with the Service information. Refer to MODULE, OCCUPANT RESTRAINT CONTROLLER, REMOVAL .
   • Perform the RESTRAINTS SYSTEM VERIFICATION TEST. Refer to RESTRAINTS SYSTEM VERIFICATION TEST .

1. With the scan tool, record and erase all DTCs 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 and 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 

    • Refer to OCCUPANT RESTRAINT CONTROLLER (ORC) - DIAGNOSTIC CODE INDEX - 500 - EXCEPT ELECTRIC and perform the appropriate diagnostic procedure.

    No 

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