Diagnostic Test

WARNING: This page is about a different car, the 2019 RAM 3500 HD. However, it is still accessible from the selected car via links, so may be relevant.
  1. READ AND RECORD DTCS AND ENVIRONMENTAL DATA - ERASE DTCS AND CHECK FOR THE DTC TO RETURN 
    NOTE:

    Transmission gear ratio errors can be caused by intermittent speed sensor(s) errors or solenoid errors. If there are any speed sensor or solenoid DTCs set, perform those diagnostic tests before diagnosing any gear ratio error DTC. Review the event data and the When Monitored and Set Conditions for the DTC and attempt to duplicate the condition the DTC set.

    1. With the scan tool, read DTCs in all Electronic Control Units (ECUs) and record on the repair order.
    2. For future reference, with the scan tool, run and save a vehicle Scan Report and all related recorded data.
    3. With the scan tool, erase all DTCs.
    4. Turn the ignition off for a minimum of 10.0 seconds.
    5. Turn the ignition on.
    6. Using the When Monitored and Set Conditions above and recorded data, operate the vehicle in the conditions that set the DTC.
    7. With the scan tool, read DTCs.

    Did the DTC return?
