Diagnostic Test

WARNING: This page is about a different car, the 2011 RAM Pickup and 2011 RAM Cab & Chassis. However, it is still accessible from the selected car via links, so may be relevant.
  1. CHECK IF DTC IS CURRENT 
    1. Using the scan tool, read TCM DTCs.
    2. Record the Environmental Data and any DTCs.
    3. Clear 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. Read TCM DTCs.

      Did the DTC reset?

      Yes 

      • Go To  2.

      No 

      • Go To  8.
  2. CHECK FOR RELATED TIPM DTCS 
    1. With the scan tool, view TIPM DTCs.

      Are there any TIPM power output codes stored?

      Yes 

      No 

      • Go To  3.
  3. CHECK THE (T16) TRANSMISSION CONTROL OUTPUT CIRCUIT

    1. Turn the ignition off to the lock position.
    2. Disconnect the TCM C2 harness connector.
    3. Ignition on, engine not running.
    4. Using the scan tool, actuate the Transmission Control Output in the TIPM.
    5. Using a 12-volt test light connected to ground, check both of the (T16) Transmission Control Output circuits on the appropriate terminal of TCM C2 harness connector.
      NOTE:

      The test light must illuminate brightly. Compare the brightness to that of a direct connection to the battery.

      Does the test light illuminate brightly on both of the TCM (T16) Transmission Control Output circuits?

      Yes 

      • Using the schematics as a guide, check the Transmission Control Module (TCM) terminals for corrosion, damage, or terminal push out. Pay particular attention to all power and ground circuits. Check for Service Information Tune-ups or Service Bulletins for any possible causes that may apply. If no problems are found, replace and program the TCM in accordance with the Service Information.
      • Perform AS68RC VERIFICATION TEST. Refer to Standard Procedure .

      No 

      • Go To  4.
  4. CHECK THE (T16) TRANSMISSION CONTROL OUTPUT CIRCUIT

    1. Turn the ignition off to the lock position.
    2. Install a substitute Transmission Control relay.
    3. Ignition on, engine not running.
    4. Using the scan tool, actuate the Transmission Control Output in the TIPM.
    5. Using a 12-volt test light connected to ground, check both of the (T16) Transmission Control Output circuits on the appropriate terminal of TCM C2 harness connector.

      Does the test light illuminate brightly on both of the TCM (T16) Transmission Control Output circuits?

      Yes 

      • Replace the Transmission Control Relay.
      • Perform AS68RC VERIFICATION TEST. Refer to Standard Procedure .

      No 

      • Go To  5.
  5. CHECK THE (A916) BATTERY FEED CIRCUIT 
    1. Turn the ignition off to the lock position.
    2. Remove Transmission Control relay.
    3. Ignition on, engine not running.
    4. Using a 12-volt test light connected to ground, check the (A916) Battery Feed circuit at the Transmission Control relay harness connector.

      Does the test light illuminate brightly on the (A916) Battery Feed circuit?

      Yes 

      • Go To  6.

      No 

      • Check the (A916) Battery Feed circuit for and open or short to ground. If no problems are found, replace the TIPM in accordance with the Service Information.
      • Perform AS68RC VERIFICATION TEST. Refer to Standard Procedure .
  6. CHECK THE (T16) TRANSMISSION CONTROL OUTPUT CIRCUIT FOR AN OPEN

    1. Turn the ignition off to the lock position.
    2. Measure the resistance of the (T16) Transmission Control Output circuit between the TCM C2 harness connector and the Transmission Control relay harness connector.

      Is the resistance above 5.0 Ohms?

      Yes 

      • Repair the (T16) Transmission Control Output circuit for an open.
      • Perform AS68RC VERIFICATION TEST. Refer to Standard Procedure .

      No 

      • Go To  7.
  7. CHECK THE (T16) TRANSMISSION CONTROL OUTPUT CIRCUIT FOR A SHORT TO GROUND 
    Fig 4: Checking Transmission Control Output Circuit For A Short To Ground
    GC0111514Courtesy of CHRYSLER LLC
    1. Measure the resistance between ground and the (T16) Transmission Control Output circuit.

      Is the resistance below 100k Ohms?

      Yes 

      • Repair the (T16) Transmission Control Output circuit for a short to ground.
      • Perform AS68RC VERIFICATION TEST. Refer to Standard Procedure .

      No 

      • Using the schematics as a guide, check the Totally Integrated Power Module (TIPM) terminals for corrosion, damage, or terminal push out. Pay particular attention to all power and ground circuits. Check for Service Information Tune-ups or Service Bulletins for any possible causes that may apply. If no problems are found, replace and program the TIPM in accordance with the Service Information.
  8. 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?

      Yes 

      No 

      • Test Complete.
