B1B8C-DRIVER SEAT TRACK POSITION SENSOR CIRCUIT PERFORMANCE





For a complete wiring diagram, refer to the Wiring Information Electrical Diagrams.

- When Monitored:
While the CAN bus ignition status is in IGN_RUN, the module checks the sensor input ranges.

- Set Condition:
If the module detects that the sensor input is between 8 and 12 mA.





Always perform the Pre-Diagnostic Troubleshooting procedure before proceeding. Restraints System Pre-Diagnostic Procedure.

1. CHECK FOR ACTIVE INTERNAL FAULTS, IGNITION FAULTS, BATTERY FAULTS, OR SEAT TRACK POSITION SENSOR CIRCUIT HIGH OR LOW FAULTS IN THE OCCUPANT RESTRAINT CONTROLLER (ORC)

NOTE: Make sure the battery is fully charged

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, battery faults, or Seat Track Position Sensor Circuit High or Low faults?

Yes

- Diagnose and repair the DTCs. Testing and Inspection.
- If DTC B1B8C-DRIVER SEAT TRACK POSITION SENSOR CIRCUIT PERFORMANCE returns active, replace the ORC.
- Perform the ORC VERIFICATION TEST. Occupant Restraint Controller (ORC) Verification Test.

No

- Go To 2

2. VERIFY THAT B1B8C-DRIVER SEAT TRACK POSITION SENSOR CIRCUIT PERFORMANCE IS ACTIVE
1. With the scan tool, read ORC DTCs.

Does the scan tool display active: B1B8C-DRIVER SEAT TRACK POSITION SENSOR CIRCUIT PERFORMANCE?

Yes

- Go To 3

No

- Perform the RESTRAINTS SYSTEM INTERMITTENT TEST. . Restraints System Intermittent Condition Test

3. PERFORM SEAT TRACK POSITION SENSOR PERFORMANCE TEST
1. With the scan tool, erase ORC DTCs.
2. Turn the ignition off, wait 10 seconds and then turn the ignition on.
3. Cycle the driver seat to the full forward position and then to the full rearward position.
4. Return the driver seat to its approximate original position.
5. Wait two minutes, and then with the scan tool, read ORC DTCs.

Does the scan tool display active: B1B8C-DRIVER SEAT TRACK POSITION SENSOR CIRCUIT PERFORMANCE?

Yes

- 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 Driver Seat Track Position Sensor.
- Perform the ORC VERIFICATION TEST. Occupant Restraint Controller (ORC) Verification Test.

No

- Perform the ORC VERIFICATION TEST. Occupant Restraint Controller (ORC) Verification Test.
