Diagnostic Test

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

CHECK FOR AN ACTIVE DTC
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.
  Did the DTC return?
  
  Yes
  - Go To 2
  No
  - Perform the RESTRAINTS SYSTEM INTERMITTENT TEST. Refer to RESTRAINTS SYSTEM INTERMITTENT TEST .
  - Probing of the circuit cavities at the ORC Module body harness connectors or vehicle connectors is only to be done with a approved test lead from the test lead 10159-6 or the use of Breakout Box 8443-55 to prevent vehicle wiring harness connector damage during diagnostic procedures.
CHECK FOR ACTIVE INTERNAL FAULTS, IGNITION FAULTS, AND BATTERY FAULTS IN THE OCCUPANT RESTRAINT CONTROLLER (ORC)
1. 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 DTC INDEX .
  No
  - Go To 3
INSPECT PASSENGER SEAT HARNESS WIRES AND CONNECTORS
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.
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 RESTRAINTS SYSTEM VERIFICATION TEST. Refer to RESTRAINTS SYSTEM VERIFICATION TEST .
  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 RESTRAINTS SYSTEM VERIFICATION TEST. Refer to RESTRAINTS SYSTEM VERIFICATION TEST .
CHECK (R60) PASSENGER SEAT POSITION SENSOR DATA CIRCUIT AND (R264) PASSENGER SEAT POSITION SENSOR VOLTAGE CIRCUIT FOR A SHORT TO GROUND

1. Measure the resistance between ground and the (R60) Passenger Seat Position Sensor Data circuit.
2. Measure the resistance between ground and the (R264) Passenger Seat Position Sensor Voltage circuit.
  Is the resistance below 10k Ohms on either circuit?
  
  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 RESTRAINTS SYSTEM VERIFICATION TEST. Refer to RESTRAINTS SYSTEM VERIFICATION TEST .
  No
  - Go To 6
CHECK (R60) PASSENGER SEAT POSITION SENSOR DATA CIRCUIT AND (R264) PASSENGER SEAT POSITION SENSOR VOLTAGE CIRCUIT FOR AN OPEN
1. Disconnect the ORC harness connectors.
2. Connect the test leads to the DVOM.
3. Measure the resistance of the (R60) Passenger Seat Position Sensor Data circuit between the ORC module body harness connector cavity C1-B 37 and the Passenger Seat Track Position Sensor connector cavity 1.
4. Measure the resistance of the (R264) Passenger Seat Position Sensor Voltage circuit between the ORC module body harness connector cavity C1-B 23 and the Passenger Seat Track Position Sensor connector cavity 2.
  Is the resistance of either circuit above 5.0k 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 RESTRAINTS SYSTEM VERIFICATION TEST. Refer to RESTRAINTS SYSTEM VERIFICATION TEST .
  No
  
  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.
  
  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.
  - Replace the Passenger Seat Track Position Sensor and if code returns, replace the Occupant Restraint Controller (ORC) in accordance with the service information. Refer to MODULE, OCCUPANT RESTRAINT CONTROLLER, REMOVAL .
  - Perform the RESTRAINTS SYSTEM VERIFICATION TEST. Refer to RESTRAINTS SYSTEM VERIFICATION TEST .
