B1B95-PASSENGER SEAT TRACK POSITION SENSOR CIRCUIT OPEN





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

- 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:
This DTC may set when the module detects that the sensor input current is below 1 mA.





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 for a complete list of DTCs.

No

- Go To 2

2. VERIFY ACTIVE DTC

Does the scan tool display active B1B95-PASSENGER SEAT TRACK POSITION SENSOR CIRCUIT OPEN DTC?

Yes

- Go To 3

No

- Perform the AIRBAG SYSTEM INTERMITTENT TEST. . Airbag System Intermittent Condition Test

3. INSPECT PASSENGER 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 Passenger 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 Passenger Seat Harness.
- Perform the AIRBAG SYSTEM VERIFICATION TEST. Airbag System Verification Test.

No

- Go To 4

4. VERIFY THAT PASSENGER SEAT HARNESS IS ROUTED CORRECTLY
1. Verify that the Passenger Seat Harness is routed correctly.

Is the Passenger Seat Harness routed correctly?

Yes

- Go To 5

No

- Reroute the Passenger Seat Harness as necessary.
- Perform the AIRBAG SYSTEM VERIFICATION TEST. Airbag System Verification Test.

5. CHECK FOR DTC B1B95-PASSENGER SEAT TRACK POSITION SENSOR CIRCUIT OPEN WITH PASSENGER 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 Passenger Seat Track Position Sensor connector.

WARNING: Turn the ignition on, then reconnect the 12-volt battery. 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 B1B95-PASSENGER SEAT TRACK POSITION SENSOR CIRCUIT OPEN DTC?

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 Passenger Seat Track Position Sensor.
- Perform the AIRBAG SYSTEM VERIFICATION TEST. Airbag System Verification Test.

6. CHECK (R262) PASSENGER SEAT TRACK POSITION SENSOR SIGNAL CIRCUIT AND (R264) PASSENGER SEAT TRACK POSITION SENSOR SUPPLY 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 connectors.
2. Connect the SRS Load Tool Adapter 8443-32-R to the ORC connectors.

WARNING: Turn the ignition on, then reconnect the 12-volt battery. Wait two minutes before proceeding. Failure to follow these instructions may result in possible serious or fatal injury.

3. Measure the voltage of the (R262) Passenger Seat Track Position Sensor Signal circuit between the Passenger Seat Track Position Sensor connector and ground.
4. Measure the voltage of the (R264) Passenger Seat Track Position Sensor Supply circuit between the Passenger Seat Track Position Sensor connector and ground.

NOTE: Do not attempt to repair the Seat Harness. Replace the Seat Harness if any of these conditions exist

Is there any voltage on the R262 or R264 circuit?

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.
Replace the Passenger Seat Harness.
- Perform the AIRBAG SYSTEM VERIFICATION TEST. Airbag System Verification Test.

No

- Go To 7

7. CHECK (R262) PASSENGER SEAT POSITION SENSOR SIGNAL CIRCUIT FOR A SHORT TO (R264) PASSENGER SEAT TRACK POSITION SENSOR SUPPLY 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 (R262) Passenger Seat Track Position Sensor Signal circuit and the (R264) Passenger Seat Track Position Sensor Supply circuit in the Passenger Seat Track Position Sensor connector.

NOTE: Do not attempt to repair the Seat Harness. Replace the Seat Harness if any of these conditions exist

Is the resistance below 10k Ohms?

Yes

- Replace the Passenger Seat Harness.
- Perform the AIRBAG SYSTEM VERIFICATION TEST. Airbag System Verification Test.

No

- Replace the ORC.
- Perform the AIRBAG SYSTEM VERIFICATION TEST. Airbag System Verification Test.
