Diagnostic Test

READ AND RECORD DTCS AND ENVIRONMENTAL DATA - ERASE DTCS AND CHECK FOR DTC TO RETURN
1. With the scan tool, read ORC DTCs and record on the repair order.
2. Record the Environmental Data.
3. With the scan tool, erase DTCs.
4. Using the recorded Environmental Data, along with the When Monitored and Set Conditions above, operate the vehicle in the conditions that set the DTC.
5. With the scan tool, read ORC DTCs.

Yes
- Go To 2
No
- Perform the RESTRAINTS SYSTEM INTERMITTENT TEST. Refer to RESTRAINTS SYSTEM INTERMITTENT TEST .
VERIFY THE RELATED SEAT TRACK POSITION SENSOR UNUSED CIRCUITS FOR A SHORT TO VOLTAGE, SHORT TO GROUND, OR SHORT TOGETHER
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.

CAUTION:
Probing of the circuit cavities at the Occupant Restraint Controller (ORC) body harness connectors and in-line connectors using test kit 2022900080 for back probing the terminal will prevent vehicle wiring harness connector damage during diagnostic procedures.
1. Isolate the circuit(s) by disconnecting the Electronic Control Unit (ECU) and the component harness connector containing the circuit being tested. Note: Use the appropriate SYSTEM WIRING DIAGRAM as a guide to follow the path of the circuit.
2. Check any unused circuits at the related seat track position sensor for possible short to voltage.
3. Check any unused circuits at the related seat track position sensor for possible short to ground.
4. Check any unused circuits at the related seat track position sensor for possible short together.
  Are any of the unused circuits at the related seat track position sensor shorted?
  
  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.
  - Repair any unused circuits at the related seat track position sensor that are shorted. Use the appropriate SYSTEM WIRING DIAGRAM as a guide to trace the circuit and look for any in-line connectors to help isolate the location of the short.
  - Perform the RESTRAINTS SYSTEM INTERMITTENT TEST. Refer to RESTRAINTS SYSTEM INTERMITTENT TEST .
  No
  - Go To 3
REPLACE THE SEAT TRACK POSITION SENSOR
1. Replace the Seat Track Position Sensor in accordance with the Service Information. Refer to SENSOR, SEAT TRACK POSITION, REMOVAL AND INSTALLATION .
2. Perform the RESTRAINTS SYSTEM VERIFICATION TEST. Refer to RESTRAINTS SYSTEM VERIFICATION TEST .
  Did the DTC return?
  
  Yes
  
  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 Service Information. Refer to CONTROLLER, OCCUPANT RESTRAINT (ORC), REMOVAL AND INSTALLATION .
  - Perform the RESTRAINTS SYSTEM VERIFICATION TEST. Refer to RESTRAINTS SYSTEM VERIFICATION TEST .
  No
  - The replacement of the Seat Track Position Sensor corrected the concern.
  - Test complete.
