Diagnostic Test

WARNING: This page is about a different car, the 2011 RAM Pickup. However, it is still accessible from the selected car via links, so may be relevant.
  1. CHECK FOR RELATED DTCS 
    1. With the scan tool, check DTCs.

      Are there any TIPM TCM Power Control Circuit and/or TCM Power Input DTCs present?

      Yes 

      • Refer to appropriate Electrical Diagnostic Information and perform the appropriate diagnostic procedure .

      No 

      • Go To  2.
  2. CHECK IF THE DTC IS CURRENT 
    1. With the scan tool, read DTCs.

      Is the status Active or is the Starts Since Set counter 0 for this DTC?

      Yes 

      • Go To  3.

      No 

      • Go To  5.
  3. CHECK THE PRESSURE SIGNAL CIRCUITS FOR A SHORT TO VOLTAGE

    1. Turn the ignition off to the lock position.
    2. Disconnect the PCM C2 harness connector.
    3. Disconnect the Transmission Solenoid/TRS Assembly harness connector.
    4. Ignition on, engine not running.
    5. With the scan tool under TIPM, actuate the Transmission.
    6. Measure the voltage of the (T147) 2C, (T48) 4C, (T50) L/R, (T9) OD, and (T29) UD Pressure Signal circuits.

      Is the voltage above 0.5 of a volt on any of the measured circuits?

      Yes 

      • Repair the (T147) 2C, (T48) 4C, (T50) L/R, (T9) OD, and/or (T29) UD Pressure Signal circuit(s) for a short to voltage.
      • Perform the appropriate TRANSMISSION VERIFICATION TEST. Refer to 68RFE TRANSMISSION VERIFICATION TEST  .

      No 

      • Go To  4.
  4. CHECK THE TRANSMISSION SOLENOID/TRS ASSEMBLY

    1. With the scan tool under TIPM, stop the Transmission actuation.
    2. Turn the ignition off to the lock position.
    3. Reconnect the Transmission Solenoid/TRS Assembly harness connector.
    4. Ignition on, engine not running.
    5. Measure the voltage of the (T147) 2C, (T48) 4C, (T50) L/R, (T9) OD, and (T29) UD Pressure Signal circuits.

      Is the voltage above 0.5 of a volt on any of the measured circuits?

      Yes 

      • Replace the Transmission Solenoid/TRS Assembly in accordance with the Service Information.
      • Perform the appropriate TRANSMISSION VERIFICATION TEST. Refer to 68RFE TRANSMISSION VERIFICATION TEST  .

      No 

      • Using the schematics as a guide, check the Powertrain Control Module (PCM) terminals for corrosion, damage, or terminal push out. Pay particular attention to all power and ground circuits. If no problems are found, replace the PCM in accordance with the Service Information. With the scan tool, perform Quick Learn.
      • Perform the appropriate TRANSMISSION VERIFICATION TEST. Refer to 68RFE TRANSMISSION VERIFICATION TEST  .
  5. CHECK THE WIRING AND CONNECTORS 
    1. The conditions necessary to set this 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. With the scan tool, check the Event Data to help identify the conditions in which the DTC was set.

      Where there any problems found?

      Yes 

      No 

      • Test Complete.
