B00B5-13






B00B5-13-DRIVER TRACK POSITION SENSOR - CIRCUIT OPEN





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 sensor and wiring.

- When Monitored:
While the Controller Area Network (CAN) bus ignition status is in IGN_RUN and the module is configured for a seat track position sensor, the module checks the sensor input current ranges. Monitoring is continuous at a rate of every 60ms.

- Set Condition:
This Diagnostic Trouble Code (DTC) may set when the module detects that the sensor input current is below 1 mA. This fault will go from active to stored status upon the open fault clearing for 5 seconds.





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

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

- Testing and Inspection Perform the appropriate diagnostic procedure.

No

- Go To 2

2. VERIFY THAT DTC B00B5-13-DRIVER TRACK POSITION SENSOR - CIRCUIT OPEN

Does the scan tool display active B00B5-13-DRIVER TRACK POSITION SENSOR - CIRCUIT OPEN?

Yes

- Go To 3

No

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

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 driver seat harness. Replace the driver seat harness if any of these conditions exist.

- Replace the driver seat harness.
- Perform the RESTRAINTS SYSTEM VERIFICATION TEST. Restraints System Verification Test.

No

- Go To 4

4. VERIFY THE DRIVER SEAT HARNESS IS ROUTED CORRECTLY
1. Verify 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 B00B5-13-DRIVER TRACK POSITION SENSOR - CIRCUIT OPEN 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 harness 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, then using a scan tool, read ORC DTCs.

Does the scan tool display: B00B5-13-DRIVER 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. Seat Track Position Sensor - Removal.
- Perform the RESTRAINTS SYSTEM VERIFICATION TEST. Restraints System Verification Test.

6. CHECK (R261) DRIVER SEAT POSITION SENSOR DATA CIRCUIT AND (R263) DRIVER 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 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. Measure the voltage of the (R261) driver seat position sensor data circuit between the driver seat track position sensor harness connector and ground.
3. Measure the voltage of the (R263) Driver Seat Position Sensor Voltage circuit between the driver seat track position harness connector and ground.

Is the voltage above 0.2 of a Volt for either circuit?

Yes

- NOTE: Do not attempt to repair the driver seat harness. Replace the driver seat harness if any of these conditions exist.

- WARNING: To avoid serious or fatal injury, 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

- Go To 7

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

No

- Replace the ORC. Occupant Restraint Controller - Removal.
