Diagnostic Test

WARNING: This page is about a different car, the 2016 Jeep Wrangler and 2015 Jeep Wrangler. However, it is still accessible from the selected car via links, so may be relevant.

IDENTIFYING VEHICLE EQUIPMENT
NOTE:
Make sure the battery is fully charged.
1. Turn the ignition on.
2. Using the scan tool, read ORC active DTCs.
  Does the scan tool display active DTC: B1B93-PASSENGER SEAT TRACK POSITION SENSOR CIRCUIT LOW?
  
  Yes
  - Go To 2
  No
  - Perform the AIRBAG SYSTEM INTERMITTENT TEST. Refer to STANDARD PROCEDURE .
CHECK FOR ACTIVE INTERNAL FAULTS, IGNITION FAULTS, AND BATTERY FAULTS IN THE OCCUPANT RESTRAINT CONTROLLER (ORC)
1. Using 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. Refer to OCCUPANT RESTRAINT CONTROLLER (ORC) - DIAGNOSTIC CODE INDEX .
  No
  - Go To 3
INSPECT PASSENGER 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.
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 in accordance with the Service Information.
  - Perform the AIRBAG SYSTEM VERIFICATION TEST. Refer to STANDARD PROCEDURE .
  No
  - Go To 4
VERIFY THAT PASSENGER SEAT HARNESS IS ROUTED CORRECTLY
1. 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. Refer to STANDARD PROCEDURE .

1. Disconnect the ORC harness connectors.
2. Connect the SRS Load Tool Adapter (special tool #8443-32-L, Adapter, SRS Adapter) or (special tool #8443-32-R, Adapter, SRS Adapter) to the ORC harness connector.
3. Measure the resistance between ground and the (R264) Passenger Seat Position Sensor voltage circuit of the appropriate terminal of the SRS Load Tool Adapter (special tool #8443-32-L, Adapter, SRS Adapter) or (special tool #8443-32-R, Adapter, SRS Adapter).
  Is the resistance below 10k 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 in accordance with the service information.
  - Perform the AIRBAG SYSTEM VERIFICATION TEST. Refer to STANDARD PROCEDURE .
  No
  - Go To 6

1. Measure the resistance between the (R262) Passenger Seat Position Sensor Data circuit and the (R264) Passenger Seat Position Sensor voltage circuit.
  Is the resistance below 10k 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 in accordance with the Service Information.
  - Perform the AIRBAG SYSTEM VERIFICATION TEST. Refer to STANDARD PROCEDURE .
  No
  - Go To 7
CHECK OPERATION OF THE PASSENGER SEAT TRACK POSITION SENSOR
1. Replace the Passenger Seat Track Position Sensor in accordance with the Service Information.
2. Reconnect the vehicle body harness to the Passenger Seat Track Position sensor.
3. Remove any special tools or jumper wires and reconnect all previously disconnected components - except the Battery.
  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.
4. Connect the scan tool to the Data Link Connector - use the most current software available.
5. Use the scan tool and erase the stored codes in all airbag system modules.
6. Turn the Ignition Off, and wait 15 seconds before turning the Ignition On.
7. Wait one minute, and read active codes and if there are none present read the stored codes.
  Did the active Passenger Seat Track Position Sensor DTC return?
  
  Yes
  
  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.
  - Replace the Occupant Restraint Controller (ORC) in accordance with the service information.
  - Perform the AIRBAG SYSTEM VERIFICATION TEST. Refer to STANDARD PROCEDURE .
  No
  - Repair is complete.
  - Perform the AIRBAG SYSTEM VERIFICATION TEST. Refer to STANDARD PROCEDURE .
