Diagnostic Test

WARNING: This page is about a different variant/trim than selected.
  1. 1)  CHECK IF RELATED TCM DTCS ARE PRESENT 

    With the scan tool, read Transmission DTCs

    Are there any TCM Power Input DTCs present also? 

    Yes 

    1. Refer to DIAGNOSTIC CODE INDEX and perform the appropriate diagnostic procedure(s).

    No 

    1. Go To step  2).
  2. 2)  CHECK IF THE DTC IS CURRENT 

    With the scan tool, view DTCs.

    Is the status Active or is the STARTS SINCE SET counter set at 0 for this DTC? 

    Yes 

    1. Go To step  3).

    No 

    1. Go To step  7).
  3. 3)  CHECK THE PCM AND WIRING USING THE TRANSMISSION SIMULATOR 

    Turn the ignition off to the lock position.

    Remove the Ignition Switch Feed fuse from the TIPM.

    CAUTION: Removal of the Ignition Switch Feed fuse from the TIPM will prevent the vehicle from being started in gear.
    WARNING: The Ignition Switch Feed fuse must be removed from the TIPM. Failure to do so can result in personal injury or death.

    Install the Transmission Simulator, Miller tool #8333 and the Electronic Transmission Adapter kit 8333-1A.

    Ignition on, engine not running.

    With the scan tool, actuate the UD Solenoid.

    Monitor the UD Solenoid LED on the Transmission Simulator.

    Did the UD Solenoid LED on the Transmission Simulator blink on and off during actuation? 

    Yes 

    1. Replace Transmission Solenoid/Pressure Switch Assembly per the Service Information.
    2. Perform 40/41 TE TRANSMISSION VERIFICATION TEST - VER 1  .

    No 

    1. Go To step  4).
  4. 4)  CHECK THE (T59) UD SOLENOID CONTROL CIRCUIT FOR AN OPEN

    Turn the ignition off to the lock position.

    Disconnect the PCM C4 harness connector.

    Disconnect the Transmission Solenoid/Pressure Switch Assembly harness connector.

    CAUTION: Do not probe the PCM harness connectors. Probing the PCM harness connectors will damage the PCM terminals resulting in poor terminal to pin connection. Install Miller Special Tool #8815 to perform diagnosis.

    Measure the resistance of the (T59) UD Solenoid Control circuit from the appropriate terminal of special tool #8815 to the Solenoid/Pressure Switch Assembly harness connector.

    Is the resistance above 5.0 ohms? 

    Yes 

    1. Repair the (T59) UD Solenoid Control circuit for an open.
    2. Perform 40/41 TE TRANSMISSION VERIFICATION TEST - VER 1  .

    No 

    1. Go To step  5).
  5. 5)  CHECK THE (T59) UD SOLENOID CONTROL CIRCUIT FOR A SHORT TO GROUND 
    Fig 2: Checking UD Solenoid Control Circuit

    Measure the resistance between ground and the (T59) UD Solenoid Control circuit.

    Is the resistance below 5.0 ohms? 

    Yes 

    1. Repair the (T59) UD Solenoid Control circuit for a short to ground.
    2. Perform 40/41 TE TRANSMISSION VERIFICATION TEST - VER 1  .

    No 

    1. Go To step  6).
  6. 6)  CHECK THE (T59) UD SOLENOID CONTROL CIRCUIT FOR A SHORT TO VOLTAGE 
    Fig 3: Checking UD Solenoid Control Circuit

    Ignition on, engine not running.

    With the scan tool in the TIPM, actuate the TCM output.

    Measure the voltage of the (T59) UD Solenoid Control circuit.

    Is the voltage above 0.5 volts? 

    Yes 

    1. Repair the (T59) UD Solenoid Control circuit for a short to voltage.
    2. Perform 40/41 TE TRANSMISSION VERIFICATION TEST - VER 1  .

    No 

    1. 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. Check for Service Information Tune-ups or Service Bulletins for any possible causes that may apply. If no problems are found, replace the PCM per the Service Information. With the scan tool, perform QUICK LEARN.
    2. Perform 40/41 TE TRANSMISSION VERIFICATION TEST - VER 1  .
  7. 7)  INTERMITTENT WIRING AND CONNECTORS 

    The conditions necessary to set the DTC are not present at this time.

    Using the schematics as a guide, inspect the wiring and connectors specific to this circuit.

    Wiggle the wires while checking for shorted and open circuits.

    With the scan tool, check the DTC EVENT DATA to help identify the conditions in which the DTC was set.

    Were there any problems found? 

    Yes 

    1. Repair as necessary.
    2. Perform 40/41 TE TRANSMISSION VERIFICATION TEST - VER 1  .

    No 

    1. Test Complete.
