B00B5-12-DRIVER SEAT TRACK POSITION SENSOR - CIRCUIT SHORT TO BATTERY





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

Theory of Operation

When powered, the Occupant Restraint Controller (ORC) sends a test current to the seat track position sensors to verify the integrity of the sensors and wiring.

- When Monitored:
While the CAN bus ignition status is in IGN_RUN with a minimum of 8.5 volts at startup and the module is configured for a Driver Seat Track Position Sensor, the module checks the sensor input current ranges. Monitoring is continuous at a rate of every 60ms.

- Set Condition:
If the module detects that the sensor input is greater than 5K Ohms for a minimum of 2.5 seconds. This fault will go from active to stored status upon the short to battery fault clearing for 5 seconds.





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

1. IDENTIFYING VEHICLE EQUIPMENT

NOTE: Make sure 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: B00B5-12-DRIVER SEAT TRACK POSITION SENSOR - CIRCUIT SHORT TO BATTERY?

Yes

- Go To 2

No

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

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

- Diagnose and repair the DTCs. Testing and Inspection.

No

- Go To 3

3. INSPECT DRIVER SEAT HARNESS WIRES AND CONNECTORS

WARNING: Turn the ignition off, disconnect the 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 the condition inspecting or testing for is present in the Seat Harness.

- Replace the driver seat harness.
- Perform the RESTRAINTS SYSTEM INTERMITTENT TEST. Restraints System Intermittent Condition Test.

No

- Go To 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 5

No

- Reroute the driver seat harness as necessary.
- Perform the RESTRAINTS SYSTEM VERIFICATION TEST. Restraints System Verification Test.

5. CHECK FOR DTC B00B5-12-DRIVER SEAT TRACK POSITION SENSOR - CIRCUIT SHORT TO BATTERY WITH DRIVER SEAT TRACK POSITION SENSOR DISCONNECTED

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. Disconnect the Driver Seat Track Position Sensor connector.If the vehicle is equipped with the standard key ignition, follow this ignition on warning.

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.
If the vehicle is equipped with the keyless ignition, follow this ignition on warning.

WARNING: Disconnect the 12-volt battery wait two minutes before proceeding, remove the ORC fuses, connect the 12-volt battery, wait two minutes before proceeding. Cycle the ignition to the On position, then reconnect the ORC fuses. 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: B00B5-12-DRIVER SEAT TRACK POSITION SENSOR - CIRCUIT SHORT TO BATTERY?

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. Seat Track Position Sensor - Removal.
- Perform the RESTRAINTS SYSTEM VERIFICATION TEST. Restraints System Verification Test.

6. CHECK (R261) DRIVE SEAT POSITION SENSOR DATA CIRCUIT AND (R263) DRIVE SEAT POSITION SENSOR VOLTAGE CIRCUIT FOR A SHORT TO VOLTAGE





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. Disconnect the ORC harness connectors.If the vehicle is equipped with the standard key ignition, follow this ignition on warning.

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.
If the vehicle is equipped with the keyless ignition, follow this ignition on warning.

WARNING: Disconnect the 12-volt battery wait two minutes before proceeding, remove the ORC fuses, connect the 12-volt battery, wait two minutes before proceeding. Cycle the ignition to the On position, then reconnect the ORC fuses. Wait two minutes before proceeding. Failure to follow these instructions may result in possible serious or fatal injury.

2. Measure the voltage of the (R261) Driver Seat Position Sensor Data circuit at the Driver Seat Track Position Sensor harness connector cavity 1.
3. Measure the voltage of the (R263) Driver Seat Position Sensor Voltage circuit at the Driver Seat Track Position Sensor harness connector cavity 2.

Is the voltage above 0.2 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 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.
- Perform the RESTRAINTS SYSTEM VERIFICATION TEST. Restraints System Verification Test.

No

- Perform the RESTRAINTS SYSTEM VERIFICATION TEST. Restraints System Verification Test.

7. CHECK (R261) DRIVER SEAT POSITION SENSOR DATA CIRCUIT FOR A SHORT TO THE (R263) DRIVER SEAT POSITION SENSOR VOLTAGE CIRCUIT





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. Measure the resistance between the (R261) Driver Seat Position Sensor Data circuit cavity 1 and the (R263) Driver Seat Position Sensor Voltage circuit cavity 2 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 the condition inspecting or testing for is present in the Seat Harness.

- Replace the Driver Seat Harness.
- Perform the RESTRAINTS SYSTEM VERIFICATION TEST. Restraints System Verification Test.

No

- Replace the ORC. Occupant Restraint Controller - Removal.
