B1B94
B1B94-PASSENGER SEAT TRACK POSITION SENSOR CIRCUIT HIGH
For a complete wiring diagram Consult Diagrams/Electrical.
- When Monitored:
While the CAN bus ignition status is in IGN_RUN and the module is configured for a Passenger 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 20.5 mA. This DTC may set when the current is between 17 mA and 20.5 mA.
Diagnostic Test
1. IDENTIFYING VEHICLE EQUIPMENT
NOTE: Ensure the battery is fully charged.
Turn the ignition on.
With the scan tool, read ORC active DTCs.
Does the scan tool display active DTC: B1B94-PASSENGER SEAT TRACK POSITION SENSOR CIRCUIT HIGH?
Yes
- Go to 2
No
- Go to 7
Diagnostic Test
2. 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 3
3. INSPECT PASSENGER SEAT HARNESS WIRES AND CONNECTORS
WARNING: To avoid serious or fatal injury, 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 the condition inspecting or testing for is present in the Seat Harness.
- Replace the passenger seat harness.
- Perform the *AIRBAG SYSTEM VERIFICATION TEST - VER 1. Airbag System Verification Test
No
- Go to 4
4. VERIFY THAT PASSENG1ER 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 the *AIRBAG SYSTEM VERIFICATION TEST - VER 1. Airbag System Verification Test
5. CHECK FOR DTC B1B94-PASSENGER SEAT TRACK POSITION SENSOR CIRCUIT HIGH WITH PASSENGER SEAT TRACK POSITION SENSOR DISCONNECTED
WARNING: To avoid serious or fatal injury, turn the ignition off, disconnect the battery and wait two minutes before proceeding.
Disconnect the Passenger Seat Track Position Sensor connector.
WARNING: To avoid serious or fatal injury, 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: B1B94-PASSENGER SEAT TRACK POSITION SENSOR CIRCUIT HIGH?
Yes
- Go to 6
No
WARNING: To avoid serious or fatal injury, turn the ignition off, disconnect the battery and wait two minutes before proceeding.
Replace the Passenger Seat Track Position Sensor.
- Perform the *AIRBAG SYSTEM VERIFICATION TEST - VER 1. 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: To avoid serious or fatal injury, turn the ignition off, disconnect the battery and wait two minutes before proceeding.
Disconnect the both ORC connectors.
WARNING: To avoid serious or fatal injury, turn the ignition on, then reconnect the battery.
Measure the voltage of the (R262) Passenger Seat Position Sensor Data circuit at the Passenger Seat Track Position Sensor connector.
Measure the voltage of the (R263) Passenger Seat Position Sensor Voltage circuit at the Passenger Seat Track Position Sensor connector.
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 the condition inspecting or testing for is present in the Seat Harness.
WARNING: To avoid serious or fatal injury, turn the ignition off, disconnect the battery and wait two minutes before proceeding.
Replace the Passenger Seat Harness.
- Perform the *AIRBAG SYSTEM VERIFICATION TEST - VER 1. Airbag System Verification Test
No
- Repair is complete.
- Perform the *AIRBAG SYSTEM VERIFICATION TEST - VER 1. Airbag System Verification Test
7. 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 serious or fatal injury, 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 serious or fatal injury, 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 serious or fatal injury, 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
- Diagnose and repair the DTC(s).
No
- No problem found at this time. Erase all codes before returning vehicle to customer.
