B1B95






B1B95-PASSENGER SEAT TRACK POSITION SENSOR CIRCUIT OPEN







- 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.

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

- Perform the AIRBAG SYSTEM INTERMITTENT TEST. Initial Inspection and Diagnostic Overview.

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 (R262) PASSENGER SEAT POSITION SENSOR DATA CIRCUIT AND (R264) PASSENGER SEAT POSITION SENSOR VOLTAGE CIRCUIT FOR AN OPEN




1. Disconnect the ORC connectors.
2. Connect the SRS Load Tool Adaptor 8443-25 to the ORC C2 connector.
3. Measure the resistance of the (R262) Passenger Seat Position Sensor Data circuit between the SRS Load Tool Adaptor 8443-25 cavity 32-25 and the Passenger Seat Track Position Sensor connector cavity 1.





4. Measure the resistance of the (R264) Passenger Seat Position Sensor Voltage circuit between the SRS Load Tool Adaptor 8443-25 cavity 32-26 and the Passenger Seat Track Position Sensor connector cavity 2.

Is the resistance of either circuit above 5.0 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 Passenger Seat Harness.
- Perform the AIRBAG SYSTEM VERIFICATION TEST. Airbag System Verification Test.

No

- Go To 6

6. CHECK OPERATION OF THE PASSENGER SEAT TRACK POSITION SENSOR
1. Replace the Passenger Seat Track Position Sensor.
2. Reconnect the vehicle body harness to the Seat Track Position Sensor.
3. Remove any special tools or jumper wires and reconnect all previously disconnected components - except the Battery.

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.

4. Connect the scan tool to the Data Link Connector - use the most current software available.
5. Use the scan tool and erase the stored codes in all airbag system modules.
6. Turn the Ignition Off, and wait 15 seconds before turning the Ignition On.
7. Wait one minute, and read active codes and if there are none present read the stored codes.

Did the active Passenger Seat Track Position Sensor DTC return?

Yes

- WARNING: If the Occupant Restraint Controller (ORC) is dropped at any time, it must be replaced. Failure to follow these instructions may result in possible serious or fatal injury.

- 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 Occupant Restraint Controller (ORC ).
- Perform the AIRBAG SYSTEM VERIFICATION TEST. Airbag System Verification Test.

No

- Repair is complete.
- Perform the AIRBAG SYSTEM VERIFICATION TEST. Airbag System Verification Test.
