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.
  1. CHECK FOR AN ACTIVE DTC 
    1. Turn the ignition on.
    2. Turn the Radio on.
    3. With the scan tool, read DTCs.

      Does the scan tool display this DTC as active?

      Yes 

      • Go To  2

      No 

      • Test complete. The condition or conditions that originally set this DTC are not present at this time. Using the wiring diagrams as a guide, check all related splices and connectors for signs of water intrusion, corrosion, pushed out or bent terminals and correct pin tension.
      • Perform the BODY VERIFICATION TEST. Refer to BODY VERIFICATION TEST .
  2. CHECK THE (X970), (X971) AND (X972) RADIO CIRCUITS FOR A SHORT TO VOLTAGE IN THE HARNESS 
    1. Turn the ignition off.
    2. Disconnect the Radio harness connectors.
    3. Disconnect the Camera harness connector.
    4. Turn the ignition on.
    5. Check for voltage present on the (X970), (X971) and (X972) Camera circuits.

      Is there any voltage present?

      Yes 

      • Repair the Camera circuit with the short to voltage.
      • Perform the BODY VERIFICATION TEST. Refer to BODY VERIFICATION TEST .

      No 

      • Go To  3
  3. CHECK THE (X970), (X971) AND (X972) CAMERA CIRCUITS FOR A SHORT TO GROUND IN THE HARNESS 
    1. Turn the ignition off.
    2. Disconnect the Radio harness connectors.
    3. Disconnect the Camera harness connector.
    4. Turn the ignition on.
    5. Measure the resistance between ground and the (X970), (X971) and (X972) Camera circuits.

      Is the resistance below 10K Ohms?

      Yes 

      • Repair the Camera circuit with the short to ground.
      • Perform the BODY VERIFICATION TEST. Refer to BODY VERIFICATION TEST .

      No 

      • Go To  4
  4. CHECK THE (X970), (X971) AND (X972) CAMERA CIRCUITS FOR A SHORT TOGETHER 
    1. Disconnect the Radio harness connector.
    2. Measure the resistance between the (X970), (X971) and (X972) Camera circuits.

      Is the resistance below 10K Ohms?

      Yes 

      • Repair the Camera circuits that are shorted together.
      • Perform the BODY VERIFICATION TEST. Refer to BODY VERIFICATION TEST .

      No 

      • Go To  5
  5. CHECK THE (X970), (X971) AND (X972) CAMERA CIRCUITS FOR AN OPEN IN THE HARNESS 
    1. Turn the ignition off.
    2. Measure the resistance of the (X970), (X971) and (X972) Camera circuit between the Camera harness connectors and the Radio harness connector.

      Is the resistance below 5.0 Ohms?

      Yes 

      • Replace the Backup Camera in accordance with the service information. Refer to REAR CAMERA, REMOVAL .
      • Go To  6

      No 

      • Repair the Camera circuit with the open.
      • Perform the BODY VERIFICATION TEST. Refer to BODY VERIFICATION TEST .
  6. CHECK FOR AN ACTIVE DTC 
    1. Turn the ignition on.
    2. Turn the Radio on.
    3. With the scan tool, read DTCs.
