2023 Dodge and Ram Durango SRT 392 PlusSECTION Diagnostic Test
  1. CHECK FOR AN ACTIVE DIAGNOSTIC TROUBLE CODE (DTC) 
    1. With the scan tool, read DTCs in all Electronic Control Units (ECUs) and record on the repair order.
    2. For future reference, run and save a vehicle Scan Report and all related recorded data.
    3. With the scan tool, erase all DTCs.
    4. Turn the ignition on.
    5. Using the When Monitored and Set Conditions above and recorded data, operate the vehicle in the conditions that set the DTC.
    6. 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.
