Diagnostic Test
- CHECK FOR ACTIVE INTERNAL FAULTS, IGNITION FAULTS, AND BATTERY FAULTS IN THE OCCUPANT RESTRAINT CONTROLLER (ORC) NOTE: Ensure battery is fully charged.
- 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. Refer to DIAGNOSTIC CODE INDEX or DTC-Based Diagnostics/CONTROLLER, Occupant Restraint (ORC) - Diagnosis and Testing .
No
- Go to step 2
- With the scan tool, read Occupant Restraint Controller (ORC) DTCs.
- VERIFY THAT DTC B1B8E-DRIVER SEAT TRACK POSITION SENSOR CIRCUIT HIGH IS ACTIVE
Does the scan tool display active: B1B8E-DRIVER SEAT TRACK POSITION SENSOR CIRCUIT HIGH?
Yes
- Go to step 3
No
- Perform the RESTRAINTS SYSTEM INTERMITTENT TEST. See DTC-Based Diagnostics/CONTROLLER, Occupant Restraint (ORC) - Standard Procedure .
- INSPECT DRIVER 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.
- Using the SYSTEM WIRING DIAGRAMS
as a guide, inspect the Driver 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
- Replace the Driver Seat Harness in accordance with the Service Information.
- Perform the ORC VERIFICATION TEST. See DTC-Based Diagnostics/CONTROLLER, Occupant Restraint (ORC) - Standard Procedure .
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.No
- Go to step 4
- Using the SYSTEM WIRING DIAGRAMS
as a guide, inspect the Driver Seat Harness wiring and connectors. Look for chafed, pierced, pinched, or partially broken wires and broken, bent, pushed out, spread, corroded, or contaminated terminals.
- VERIFY THAT DRIVER SEAT HARNESS IS ROUTED CORRECTLY
- Verify that the Driver Seat Harness is routed correctly.
Is the Driver Seat Harness routed correctly?
Yes
- Go to step 5
No
- Reroute the Driver Seat Harness as necessary.
- Perform the ORC VERIFICATION TEST. See DTC-Based Diagnostics/CONTROLLER, Occupant Restraint (ORC) - Standard Procedure .
- Verify that the Driver Seat Harness is routed correctly.
- CHECK FOR DTC B1B8E-DRIVER SEAT TRACK POSITION SENSOR CIRCUIT HIGH WITH DRIVER 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.
- Disconnect the Driver Seat Track Position Sensor connector.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.
- Wait two minutes, and then with the scan tool, read ORC DTCs.
Does the scan tool display: B1B8E-DRIVER SEAT TRACK POSITION SENSOR CIRCUIT HIGH?
Yes
- Go to step 6
No
- Replace the Driver Seat Track Position Sensor in accordance with the service information.
- Perform the ORC VERIFICATION TEST. See DTC-Based Diagnostics/CONTROLLER, Occupant Restraint (ORC) - Standard Procedure .
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.
- Disconnect the Driver Seat Track Position Sensor connector.

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.- Disconnect the ORC connectors.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.
- Measure the voltage of the (R261) Driver Seat Position Sensor Data circuit at the Driver Seat Track Position Sensor connector.
- Measure the voltage of the (R263) Driver Seat Position Sensor Voltage circuit at the Driver Seat Track Position Sensor connector.
Is the voltage above 0.2 volts on either circuit?
Yes
- Replace the Driver Seat Harness in accordance with the Service Information.
- Perform the ORC VERIFICATION TEST. See DTC-Based Diagnostics/CONTROLLER, Occupant Restraint (ORC) - Standard Procedure .
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: 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.No
- Go to step 7
- Disconnect the ORC connectors.
- CHECK (R261) DRIVER SEAT POSITION SENSOR DATA CIRCUIT FOR A SHORT TO (R263) DRIVER SEAT POSITION SENSOR VOLTAGE CIRCUIT Fig 2: Checking Driver Seat Position Sensor Data Circuit For A Short To Driver Seat Position Sensor Voltage Circuit
Courtesy of CHRYSLER LLC
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.- Measure the resistance between the (R261) Driver Seat Position Sensor Data circuit and the (R263) Driver Seat Position Sensor Voltage circuit in the Driver Seat Track Position Sensor connector.
Is the resistance below 10K Ohms?
Yes
- Replace the Driver Seat Harness in accordance with the service information.
- Perform the ORC VERIFICATION TEST. See DTC-Based Diagnostics/CONTROLLER, Occupant Restraint (ORC) - Standard Procedure .
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.No
- Replace the ORC in accordance with the Service information.
- Perform the ORC VERIFICATION TEST. See DTC-Based Diagnostics/CONTROLLER, Occupant Restraint (ORC) - Standard Procedure .
- Measure the resistance between the (R261) Driver Seat Position Sensor Data circuit and the (R263) Driver Seat Position Sensor Voltage circuit in the Driver Seat Track Position Sensor connector.
