B1B95
B1B95-PASSENGER SEAT TRACK POSITION SENSOR CIRCUIT OPEN
For a complete wiring diagram refer to Diagrams/Electrical.
- 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.
Diagnostic Test
1. CHECK FOR ACTIVE INTERNAL FAULTS, IGNITION FAULTS, AND BATTERY FAULTS IN THE OCCUPANT RESTRAINT CONTROLLER (ORC)
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
- Go To 8
3. INSPECT PASSENGER SEAT HARNESS WIRES AND CONNECTORS
WARNING: To avoid personal injury or death, turn the ignition off, disconnect the battery and wait two minutes before proceeding.
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 *ORC VERIFICATION TEST - VER 1. Occupant Classification Module (OCM) System Verification Test
No
- Go To 4
4. VERIFY THAT PASSENGER SEAT HARNESS IS ROUTED CORRECTLY
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 *ORC VERIFICATION TEST - VER 1. Occupant Classification Module (OCM) System Verification Test
5. CHECK FOR DTC B1B95-PASSENGER SEAT TRACK POSITION SENSOR CIRCUIT OPEN WITH PASSENGER SEAT TRACK POSITION SENSOR DISCONNECTED
WARNING: To avoid personal injury or death, turn the ignition off, disconnect the battery and wait two minutes before proceeding.
Disconnect the Passenger Seat Track Position Sensor connector.
WARNING: To avoid personal injury or death, turn the ignition on, then reconnect the battery.
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: To avoid personal injury or death, turn the ignition off, disconnect the battery and wait two minutes before proceeding.
Replace the Passenger Seat Track Position Sensor.
- Perform the *ORC VERIFICATION TEST-VER 1. Occupant Classification Module (OCM) 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: To avoid personal injury or death, turn the ignition off, disconnect the battery and wait two minutes before proceeding.
Disconnect the ORC connectors.
WARNING: To avoid personal injury or death, turn the ignition on, then reconnect the battery.
Measure the voltage of the (R262) Passenger Seat Position Sensor Data circuit between the Passenger Seat Track Position Sensor connector and ground.
Measure the voltage of the (R264) Passenger Seat Position Sensor Voltage 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 the voltage above 0.2 volts on either circuit?
Yes
WARNING: To avoid personal injury or death, turn the ignition off, disconnect the battery and wait two minutes before proceeding.
Replace the Passenger Seat Harness.
- Perform the *ORC VERIFICATION TEST-VER 1. Occupant Classification Module (OCM) 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: To avoid personal injury or death, turn the ignition off, disconnect the battery and wait two minutes before proceeding.
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.
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 *ORC VERIFICATION TEST-VER 1. Occupant Classification Module (OCM) System Verification Test
No
- Replace the ORC.
- Perform the *ORC VERIFICATION TEST-VER 1. Occupant Classification Module (OCM) System Verification Test
8. TEST FOR AN INTERMITTENT CONDITION
With the scan tool, record and erase all DTC's from the ORC.
If any ACTIVE codes are present they must be resolved before diagnosing any stored codes.
WARNING: To avoid personal injury or death, turn the ignition off, disconnect the battery and wait two minutes before proceeding.
Using the wiring diagram/schematic as a guide, inspect the wiring and connectors.
Look for chafed, pierced, pinched, or partially broken wires and broken, bent, pushed out, spread, corroded, or contaminated terminals.
The following additional checks may assist you in identifying a possible intermittent problem.
Reconnect any disconnected components and harness connector.
WARNING: To avoid personal injury or death, turn the ignition on, then reconnect the battery.
With the scan tool monitor active codes as you work through the following steps.
WARNING: To avoid personal injury or death, maintain a safe distance from all airbags while performing the following steps.
Wiggle the wiring harness and connectors of the related airbag circuit or component.
If only stored codes return continue the test until the problem area has been isolated.
In the previous steps you have attempted to recreate the conditions responsible for setting active DTC in question.
Are any ACTIVE DTCs present?
Yes
- Select the appropriate symptom from Symptom List.
No
- No problem found at this time. Erase all codes before returning vehicle to customer.
