Diagnostic Test

WARNING: This page is about a different variant/trim than selected.
  1. 1)  CHECK TO SEE IF DTC P0890 IS PRESENT 

    With the scan tool, view DTCs.

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

    Yes 

    1. Go To step  2).

    No 

    1. Go To step  6).
  2. 2)  (T9) OD PRESSURE SWITCH SENSE CIRCUIT SHORT TO VOLTAGE

    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.

    Ignition on, engine not running.

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

    Ignition on, engine not running.

    Measure the voltage of the (T9) OD Pressure Switch Sense circuit.

    Is the voltage above 0.5 volt? 

    Yes 

    1. Repair the (T9) OD Pressure Switch Sense circuit for a short to voltage.
    2. Perform 40/41 TE TRANSMISSION VERIFICATION TEST - VER 1  .

    No 

    1. Go To step  3).
  3. 3)  (T47) 2/4 PRESSURE SWITCH SENSE CIRCUIT SHORT TO VOLTAGE

    NOTE: The jumper wire must still be in place.

    Measure the voltage of the (T47) 2/4 Pressure Switch Sense circuit.

    Is the voltage above 0.5 volt? 

    Yes 

    1. Repair the (T47) 2/4 Pressure Switch Sense circuit for a short to voltage.
    2. Perform 40/41 TE TRANSMISSION VERIFICATION TEST - VER 1  .

    No 

    1. Go To step  4).
  4. 4)  (T50) L/R PRESSURE SWITCH SENSE CIRCUIT SHORT TO VOLTAGE 
    Fig 3: Checking L/R Pressure Switch Sense Circuit

    NOTE: The jumper wire must still be in place.

    Measure the voltage of the (T50) L/R Pressure Switch Sense circuit.

    Is the voltage above 0.5 volts? 

    Yes 

    1. Repair the (T50) L/R Pressure Switch Sense circuit for a short to voltage.
    2. Perform 40/41 TE TRANSMISSION VERIFICATION TEST - VER 1  .

    No 

    1. Go To step  5).
  5. 5)  POWERTRAIN CONTROL MODULE 

    Using the schematics as a guide, inspect the wiring and connectors. Repair as necessary. Pay particular attention to all power and ground circuits.

    If there are no possible causes remaining, view repair. 

    Repair 

    1. Replace the Powertrain Control Module per the Service Information. With the scan tool perform QUICK LEARN.
    2. Perform 40/41 TE TRANSMISSION VERIFICATION TEST - VER 1  .
  6. 6)  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 wiring and connectors 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.
