B1B95






B1B95-PASSENGER SEAT TRACK POSITION SENSOR CIRCUIT OPEN

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

- 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

- Perform the appropriate DTC. Testing and Inspection.

No

- Go To 2

2. VERIFY THAT DTC B1B95-PASSENGER SEAT TRACK POSITION SENSOR CIRCUIT OPEN IS ACTIVE

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

Yes

- Go To 3

No

- Go To 8

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. 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?

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 POSITION SENSOR DATA CIRCUIT AND (R264) PASSENGER 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 connectors.

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

2. Measure the voltage of the (R262) Passenger Seat Position Sensor Data circuit between the Passenger Seat Track Position Sensor connector and ground.
3. Measure the voltage of the (R264) Passenger Seat Position Sensor Voltage circuit between the Passenger Seat Track Position Sensor connector and ground.

Is the voltage above 0.2 volts 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 Passenger Seat Harness.
- Perform the AIRBAG SYSTEM VERIFICATION TEST. Airbag System Verification Test.

No

- Go To 7

7. CHECK (R262) SEAT POSITION SENSOR DATA-PASSENGER CIRCUIT FOR A SHORT TO (R264) SEAT POSITION SENSOR VOLTAGE-PASSENGER 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 Position Sensor Data circuit and the (R264) Passenger Seat Position Sensor Voltage circuit in the Passenger Seat Track Position Sensor 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 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.

8. TEST FOR AN INTERMITTENT CONDITION
1. With the scan tool, record and erase all DTC's from the ORC.
2. If any ACTIVE codes are present they must be resolved before diagnosing any stored codes.

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.

3. Using the wiring diagram/schematic as a guide, inspect the wiring and connectors.
4. Look for chafed, pierced, pinched, or partially broken wires and broken, bent, pushed out, spread, corroded, or contaminated terminals.
5. The following additional checks may assist you in identifying a possible intermittent problem.
6. Reconnect any disconnected components and harness connector.

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

7. With the scan tool monitor active codes as you work through the following steps.

WARNING: Maintain a safe distance from all airbags while performing the following steps. Failure to follow these instructions may result in possible serious or fatal injury.

8. Wiggle the wiring harness and connectors of the related airbag circuit or component.
9. If only stored codes return continue the test until the problem area has been isolated.
10. In the previous steps you have attempted to recreate the conditions responsible for setting active DTC in question.

Are any ACTIVE DTCs present?

Yes

- Perform the appropriate DTC. Testing and Inspection.

No

- No problem found at this time. Erase all codes before returning vehicle to customer.
