Diagnostic Test

WARNING: This page is about a different car, the 2007 Chrysler PT Cruiser. However, it is still accessible from the selected car via links, so may be relevant.
  1. 1) CHECK IF RELATED TIPM TCM DTCS ARE PRESENT 

    With the scan tool, read Transmission DTCs

    Are there any Transmission Control Relay DTCs present also? 

    Yes 

    1. Refer to the applicable Transmission Information and perform the appropriate diagnostic procedure.

    No 

    1. Go to  2).
  2. 2) CHECK TO SEE IF P0755 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  3).

    No 

    1. Go to  8).
  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.

    Ignition on, engine not running.

    With the scan tool, actuate the 2/4 Solenoid.

    Monitor the 2/4 Solenoid LED on the Transmission Simulator.

    Did the 2/4 Solenoid LED on the Transmission Simulator blink on and off during actuation? 

    Yes 

    1. Go to  4).

    No 

    1. Go to  5).
  4. 4) CHECK WIRING USING THE TRANSMISSION SIMULATOR 

    With the scan tool, continue to actuate the 2/4 Solenoid.

    While monitoring the 2/4 Solenoid LED on the Transmission Simulator, wiggle the related wiring harness and connectors.

    Did the 2/4 Solenoid LED on the Transmission Simulator continue to blink on and off during the wiggle test? 

    Yes 

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

    No 

    1. Repair wiring or connectors as necessary.
    2. Perform 40/41TE TRANSMISSION VERIFICATION TEST .
  5. 5) CHECK THE (T19) 2/4 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 (T19) 2/4 Solenoid Control circuit between the Solenoid/Pressure Switch Assembly harness connector and the appropriate terminal of Miller tool #8815.

    Is the resistance above 5.0 ohms? 

    Yes 

    1. Repair the (T19) 2/4 Solenoid Control circuit for an open.
    2. Perform 40/41TE TRANSMISSION VERIFICATION TEST .

    No 

    1. Go to  6).
  6. 6) CHECK THE (T19) 2/4 SOLENOID CONTROL CIRCUIT FOR A SHORT TO GROUND 
    Fig 2: Checking 2/4 Solenoid Control Circuit For A Short To Ground

    Measure the resistance between ground and the (T19) 2/4 Solenoid Control circuit.

    Is the resistance below 5.0 ohms? 

    Yes 

    1. Repair the (T19) 2/4 Solenoid Control circuit for a short to ground.
    2. Perform 40/41TE TRANSMISSION VERIFICATION TEST .

    No 

    1. Go to  7).
  7. 7) CHECK THE (T19) 2/4 SOLENOID CONTROL CIRCUIT FOR A SHORT TO VOLTAGE 
    Fig 3: Checking 2/4 Solenoid Control Circuit For A Short To Voltage

    Ignition on, engine not running.

    With the scan tool under TIPM, actuate the Transmission.

    Measure the voltage of the (T19) 2/4 Solenoid Control circuit.

    Is the voltage above 0.5 volts? 

    Yes 

    1. Repair the (T19) 2/4 Solenoid Control circuit for a short to voltage.
    2. Perform 40/41TE TRANSMISSION VERIFICATION TEST .

    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 40/41TE TRANSMISSION VERIFICATION TEST .
  8. 8) 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.

    Check for Service Information Tune-ups or Service Bulletins for any possible causes that may apply.

    Were there any problems found? 

    Yes 

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

    No 

    1. Test Complete.
