B00C5-11-PASSENGER SEAT TRACK POSITION SENSOR - CIRCUIT SHORT TO GROUND

Special Tools:










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

Theory of Operation

When powered, the Occupant Restraint Controller (ORC) sends a test current to the seat track position sensors to verify the integrity of the sensors and wiring.

- When Monitored:
While the CAN bus ignition status is in IGN_RUN with a minimum of 8.5 volts at startup 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 resistance is greater than 5k Ohms for minimum of 2.5 seconds. This DTC will switch from an active to a stored status upon the short to ground fault clearing for longer than five seconds.





Always perform the Pre-Diagnostic Troubleshooting procedure before proceeding. Restraints System Pre-Diagnostic Procedure.

1. IDENTIFYING VEHICLE EQUIPMENT

NOTE: Make sure the battery is fully charged.

NOTE: The use of a approved special tool or Digital Multimeter such as a Fluke Meter that will not apply more than 20 milliamperes to a circuit are the only measurement tools to be used.

NOTE: Probing of the circuit cavities at the ORC Module C1-A, C1-B, or C2-A body harness connectors is only to be done with a approved test lead from the (10159), test lead 10159-6. Or a comparable test lead to prevent vehicle wiring harness connector damage during diagnostic procedures.

1. Turn the ignition on.
2. With the scan tool, read ORC active DTCs.

Does the scan tool display active DTC: B00C5-11-PASSENGER SEAT TRACK POSITION SENSOR - CIRCUIT SHORT TO GROUND?

Yes

- Go To 2.

No

- Perform the RESTRAINTS SYSTEM INTERMITTENT TEST. Restraints System Intermittent Condition Test.

2. 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.

No

- Go To 3

3. INSPECT PASSENGER SEAT HARNESS WIRES AND CONNECTORS

WARNING: Turn the ignition off, disconnect the 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 the condition inspecting or testing for is present in the Seat Harness.

- Replace the passenger seat harness.
- Perform the RESTRAINTS SYSTEM VERIFICATION TEST. Restraints 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 Driver Seat Harness routed correctly?

Yes

- Go To 5

No

- Reroute the passenger seat harness as necessary.
- Perform the RESTRAINTS SYSTEM VERIFICATION TEST. Restraints System Verification Test.

5. CHECK (R262) PASSENGER SEAT POSITION SENSOR DATA CIRCUIT AND (R264) PASSENGER SEAT POSITION SENSOR VOLTAGE CIRCUIT FOR A SHORT TO GROUND




1. Measure the resistance between ground and the (R262) Passenger Seat Position Sensor Data circuit.
2. Measure the resistance between ground and the (R264) Passenger Seat Position Sensor Voltage circuit.

Is the resistance below 10k Ohms 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.

- Replace the Passenger Seat Harness.
- Perform the RESTRAINTS SYSTEM VERIFICATION TEST. Restraints System Verification Test.

No

- Go To 6

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




1. Disconnect the ORC harness connectors.

2. Connect the test leads to the DVOM.
3. Measure the resistance of the (R262) Passenger Seat Position Sensor Data circuit between the ORC module body harness connector cavity C1-B 66 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 ORC module body harness connector cavity C1-B 65 and the Passenger Seat Track Position Sensor connector cavity 2.

Is the resistance of either circuit above 5.0k 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 RESTRAINTS SYSTEM VERIFICATION TEST. Restraints System Verification Test.

No

- WARNING: Turn the ignition off, disconnect the battery and wait two minutes before proceeding. Failure to follow these instructions may result in possible serious or fatal injury.
WARNING: If the Occupant Restraint Controller (ORC) is dropped at any time, it must be replaced. Failure to take the proper precautions can result in accidental airbag deployment.

- Replace the Occupant Restraint Controller (ORC ). Occupant Restraint Controller - Removal.
- Perform the RESTRAINTS SYSTEM VERIFICATION TEST. Restraints System Verification Test.
