Diagnostic Test

WARNING: This page is about a different car, the 2016 Dodge Journey and 2015 Dodge Journey. However, it is still accessible from the selected car via links, so may be relevant.
  1. DETERMINE ACTIVE OR STORED DTC 
    NOTE:

    Make sure the battery is fully charged.

    1. Turn the ignition on.

      Is the DTC active or stored?

      ORC - ACTIVE DTC 

      • Go To  2

      ORC - STORED DTC 

  2. 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.

    1. 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 

      NOTE:

      Do not attempt to repair the Seat Harness. Replace the Seat Harness if any of these conditions exist.

      • Go To  3
  3. VERIFY THAT THE DRIVER SEAT HARNESS IS ROUTED CORRECTLY 
    1. Verify that the Driver Seat Harness is routed correctly.

      Is the Driver Seat Harness routed correctly?

      Yes 

      • Go To  4

      No 

  4. CHECK (R261) DRIVER SEAT POSITION SENSOR DATA CIRCUIT FOR A SHORT TO (R263) DRIVER SEAT POSITION SENSOR VOLTAGE CIRCUIT

    3. Connect the (special tool #8443-28, SRS Load Tool Adapter) to the ORC harness connectors.
    4. Measure the resistance between the (R261) Driver Seat Position Sensor Data circuit and the (R263) Driver Seat Position Sensor Voltage circuit at the appropriate terminal of the (special tool #8443-28, SRS Load Tool Adapter).

      Is the resistance below 5K Ohms?

      Yes 

      NOTE:

      If the short is found in the Seat Harness, do not attempt to repair the Seat Harness. Replace the Seat Harness in accordance with the Service Information.

      • Repair or replace the (R261) Driver Seat Position Sensor Data circuit for a short to the (R263) Driver Seat Position Sensor Voltage circuit in accordance with the Service Information.

    1. Measure the resistance of the (R263) Driver Seat Position Sensor Voltage circuit between ground and the appropriate terminal of the (special tool #8443-28, SRS Load Tool Adapter).

      Is the resistance below 6K Ohms?

      Yes 

      NOTE:

      If the short is found in the Seat Harness, do not attempt to repair the Seat Harness. Replace the Seat Harness in accordance with the Service Information.

      • Repair or replace the (R263) Driver Seat Position Sensor Voltage circuit for a short to ground in accordance with the Service Information.
      • Perform the RESTRAINTS SYSTEM VERIFICATION TEST. Refer to RESTRAINTS SYSTEM VERIFICATION TEST .

      No 

      • Go To  6
  6. CHECK OPERATION OF THE DRIVER SEAT TRACK POSITION SENSOR 
    1. Replace the Driver Seat Track Position Sensor. Refer to SENSOR, SEAT TRACK POSITION, REMOVAL .
    2. Reconnect the vehicle body harness to the sensor.
    3. Reconnect the ORC harness connectors.
    4. If the vehicle is equipped with the standard key ignition, follow this ignition on warning.
      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.

    5. If the vehicle is equipped with the keyless ignition, follow this ignition on warning.
      WARNING:

      Disconnect the 12-volt battery wait two minutes before proceeding, remove the ORC fuses, connect the 12-volt battery, wait two minutes before proceeding. Cycle the ignition to the On position, then reconnect the ORC fuses. Wait two minutes before proceeding. Failure to follow these instructions may result in possible serious or fatal injury.

    6. Connect the scan tool to the Data Link Connector - use the most current software available.
    7. Use the scan tool and erase all codes in the ORC.
    8. Perform ORC module reset. Access the Miscellaneous Function menu from the ORC ECU Overview screen on the scan tool to perform this operation.
    9. Wait one minute, and read active codes.

      Did the active DTC B1B90-DRIVER SEAT TRACK POSITION SENSOR CIRCUIT SHORTED TOGETHER return?

      Yes 

      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. Failure to follow these instructions may result in possible serious or fatal injury.

      WARNING:
