Diagnostic Test

WARNING: This page is about a different car, the 2016 RAM 3500 HD. However, it is still accessible from the selected car via links, so may be relevant.
  1. CHECK FOR AN ACTIVE DTC 
    1. With the scan tool, read TCM DTCs and record on the repair order.
    2. Record the Event Data and Environmental Data.
    3. With the scan tool, erase DTCs.
    4. Using the recorded Event and 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 TCM DTCs.
      NOTE:

      If there are any other Engine and/or Transmission DTCs, diagnosis those first.

      Did the DTC return?

      Yes 

      • Go To  2

      No 

      • Go To  5
  2. CHECK THE TORQUE CONVERTER CLUTCH (TCC) OPERATION 
    1. With the scan tool, erase TCM DTCs.
    2. Road test the vehicle in a condition that will enable TCC lock up.
    3. With the scan tool, record the Engine speed and the Transmission Input speed during TCC lock up.
    4. Using the Setting Conditions listed above, calculate the TCC slip RPM.

      Is the TCC slip RPM greater than or equal to 200 RPM?

      Yes 

      • Go To  3

      No 

      • Go To  4
  3. CHECK INTERNAL TRANSMISSION 
    1. Turn the ignition off.
    2. Remove the Transmission oil pan.
    3. Check the internal transmission harness, pins, terminals, and connectors for shorts, corrosion, damage, or pushed out terminals.
    4. Visually inspect the valve body for debris, damage or leaking hydraulic paths.
    5. Visually inspect for sticking or binding Control Valve(s).

      Were any problems found?

      Yes 

      No 

  4. CHECK RELATED HARNESS CONNECTIONS 
    1. Disconnect all TCM harness connectors.
    2. Disconnect all related in-line harness connections (if equipped).
    3. Disconnect the related component harness connectors.
    4. Inspect harness connectors, component connectors, and all male and female terminals for the following conditions:
      • Proper connector installation.
      • Damaged connector locks.
      • Corrosion.
      • Other signs of water intrusion.
      • Weather seal damage (if equipped).
      • Bent terminals.
      • Overheating due to a poor connection (terminal may be discolored due to excessive current draw).
      • Terminals that have been pushed back into the connector cavity.
      • Perform a terminal drag test on each connector terminal to verify proper terminal tension.

      Repair any conditions that are found.

    5. Reconnect all TCM harness connectors. Be certain that all harness connectors are fully seated and the connector locks are fully engaged.
    6. Reconnect all in-line harness connectors (if equipped). Be certain that all connectors are fully seated and the connector locks are fully engaged.
    7. Reconnect all related component harness connectors. Be certain that all connectors are fully seated and the connector locks are fully engaged.
    8. With the scan tool, erase DTCs.
    9. Using the recorded Event and Environmental Data, along with the When Monitored and Set Conditions above, operate the vehicle in the conditions that set the DTC.
    10. With the scan tool, read TCM DTCs.

      Yes 

      No 

  5. CHECK WIRING AND CONNECTORS 
    1. The conditions necessary to set the DTC are not present at this time.
    2. Using the schematics as a guide, inspect the wiring and connectors specific to this circuit.
    3. Wiggle the wires while checking for shorted and open circuits.
    4. Check for any Service Bulletins that may apply.

      Were there any problems found?
