Diagnostic Test
- IDENTIFYING VEHICLE EQUIPMENT NOTE: Make sure the battery is fully charged.
- Turn the ignition on.
- With the scan tool, read ORC active DTCs.
Does the scan tool display active DTC: B1B8D-DRIVER SEAT TRACK POSITION SENSOR CIRCUIT LOW?
Yes
- Go to step 2
No
- Perform the AIRBAG SYSTEM INTERMITTENT TEST. See DTC-Based Diagnostics/CONTROLLER, Occupant Restraint (ORC) - Standard Procedure .
- 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
- Perform the appropriate diagnostic procedure. See DIAGNOSTIC CODE INDEX .
No
- Go to step 3
- With the scan tool, read Occupant restraint Controller (ORC) DTCs.
- 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 wiring diagram/schematic 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 AIRBAG SYSTEM 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 wiring diagram/schematic 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 AIRBAG SYSTEM VERIFICATION TEST. See DTC-Based Diagnostics/CONTROLLER, Occupant Restraint (ORC) - Standard Procedure .
- Verify that the driver seat harness is routed correctly.
- CHECK (R261) DRIVER SEAT POSITION SENSOR DATA CIRCUIT AND (R263) DRIVER SEAT POSITION SENSOR VOLTAGE CIRCUIT FOR A SHORT TO GROUND Fig 1: Checking Driver Seat Position Sensor Data Circuit & Driver Seat Position Sensor Voltage Circuit For A Short To Ground
Courtesy of CHRYSLER LLC
- Measure the resistance between ground and the (R261) Driver Seat Position Sensor Data circuit cavity 1.
- Measure the resistance between ground and the (R263) Driver Seat Position Sensor Voltage circuit cavity 2.
Is the resistance below 10k Ohms on either circuit?
Yes
- Replace the Driver Seat Harness in accordance with the service information.
- Perform the AIRBAG SYSTEM 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 6
- CHECK (R261) DRIVER SEAT POSITION SENSOR DATA CIRCUIT AND (R263) DRIVER SEAT POSITION SENSOR VOLTAGE CIRCUIT FOR AN OPEN
- Disconnect the ORC connectors.
- Connect the SRS Load Tool Adaptor 8443-25 to the ORC C1 connector.
- Measure the resistance of the (R261) Driver Seat Position Sensor Data circuit between the SRS Load Tool Adaptor 8443-25 cavity 24-7 and the Driver Seat Track Position Sensor connector cavity 1.
- Measure the resistance of the (R263) Driver Seat Position Sensor Voltage circuit between the SRS Load Tool Adaptor 8443-25 cavity 24-8 and the Driver Seat Track Position Sensor connector cavity 2.
Is the resistance of either circuit above 5.0 Ohms?
Yes
- Replace the Driver Seat Harness in accordance with the Service Information.
- Perform the AIRBAG SYSTEM 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 Occupant Restraint Controller (ORC ) in accordance with the service information.
- Perform the AIRBAG SYSTEM 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.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.
