B00B5-2B

B00B5-2B-DRIVER SEAT TRACK POSITION SENSOR - WIRES SHORTED TOGETHER





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 and the module is configured for a Seat Track Position Sensor, the module checks the sensor input current ranges.

- Set Condition:
If the module detects that the sensor input is greater than or equal to 17.1 mA. for minimum 2.5 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. 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 2

2. VERIFY THAT DTC B00B5-2B-DRIVER SEAT TRACK POSITION SENSOR - WIRES SHORTED TOGETHER IS ACTIVE

Does the scan tool display active: B00B5-2B-DRIVER SEAT TRACK POSITION SENSOR - WIRES SHORTED TOGETHER?

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 12-volt 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 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 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 B00B5-2B-DRIVER SEAT TRACK POSITION SENSOR - WIRES SHORTED TOGETHER 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, and then with the scan tool, read ORC DTCs.

Does the scan tool display: B00B5-2B-DRIVER SEAT TRACK POSITION SENSOR - WIRES SHORTED TOGETHER?

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) SEAT POSITION SENSOR DATA-DRIVER CIRCUIT AND (R263) SEAT POSITION SENSOR VOLTAGE-DRIVER 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 Sensor harness connector and ground.

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 any of these conditions exist

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