Test Procedure

WARNING: This page is about a different car, the 2006 Mercury Mariner and 2006 Ford Escape. However, it is still accessible from the selected car via links, so may be relevant.
  1. TU1 KOEO AND CONTINUOUS MEMORY DTC P1145: VERIFY THAT THE HARD FAULT IS PRESENT 
    NOTE: Clearing the TCM DTCs will erase any TCM recorded freeze frame data. Make sure to record any TCM freeze frame information before proceeding any further. Refer to the diagnostic tool instruction manual for freeze frame PID menu.
    • Clear and retrieve TCM continuous DTCs.

    Is DTC P1145 present? 

    Yes No
    GO to  TU2. GO to  TU6.
  2. TU2 CHECK THE DTCFZ PID FOR A DTC DETAIL NUMBER 
    NOTE: The DTCFZ PID is a freeze frame PID.
    • Access the TCM and monitor the DTCFZ PID.

    Does the DTCFZ PID indicate freeze detail number 41, 42, 61, 62 or 178 present? 

    Yes No
    INSTALL a new transaxle assembly. GO to  TU3.
  3. TU3 CHECK THE TCM TOTAL TORQUE DESIRED PID VALUE IN REVERSE 
    NOTE: Do not apply the brake pedal when recording the PID value because it may produce false readings.
    NOTE: Refer to diagnostic tool instruction manual for information on the recorder function.
    • Key ON, engine running.
    • Gear selector in REVERSE position.
    • Access the TCM and monitor the TQ_DSD PID.
    • Record the PID value when driving the vehicle in REVERSE.

    Is the torque between -4,000 - 0 Nm (-2,950 - 0 lb ft)? 

    Yes No
    GO to  TU4. Key in OFF position.
    GO to  TU11.
  4. TU4 CHECK THE TCM TOTAL TORQUE DESIRED PID VALUE IN DRIVE 
    NOTE: Do not apply the brake pedal during this test because it may produce false readings.
    NOTE: Refer to diagnostic tool instruction manual for information on the recorder function.
    • Gear selector in DRIVE position.
    • Access the TCM and monitor the TQ_DSD PID.
    • Record the PID value when driving the vehicle in DRIVE.

    Is the torque between 0 - 4,000 Nm (0 - 2,950 lb ft)? 

    Yes No
    GO to  TU5. Key in OFF position.
    GO to  TU11.
  5. TU5 CHECK THE TCM TOTAL TORQUE DESIRED PID VALUE IN LOW 
    NOTE: Do not apply the brake pedal during this test because it may produce false readings.
    NOTE: Refer to diagnostic tool instruction manual for information on the recorder function.
    • Gear selector in LOW position.
    • Access the TCM and monitor the TQ_DSD PID.
    • Record the PID value when driving the vehicle in LOW.

    Is the torque between 0 - 4,000 Nm (0 - 2,950 lb ft)? 

    Yes No
    INSTALL a new transaxle assembly. Key in OFF position.
    GO to  TU11.
  6. TU6 CHECK THE DTCFZ PID FOR A DTC DETAIL NUMBER 
    NOTE: The DTCFZ PID is a freeze frame PID.
    • Access the TCM and monitor the DTCFZ PID.

    Does the DTCFZ PID indicate freeze detail number 41, 42, 61, 62 or 178 present? 

    Yes No
    INSTALL a new transaxle assembly. GO to  TU7.
  7. TU7 RECREATE THE SYMPTOM USING ALL AVAILABLE DATA 
    NOTE: To recreate the original conditions that set the DTC or caused the symptom, the vehicle may require driving.
    • Access the Freeze Frame Data (if available) and record the DTC malfunction conditions.
    • Clear the TCM DTCs.
    • Obtain information from the customer information worksheet or any other available data from the customer.
    • Access the TCM and monitor the TQ_DSD PID.
    • Recreate the symptom using freeze frame and customer information.
    • When the symptom occurs, press trigger to begin recording. Refer to diagnostic tool instruction manual for information on the recorder function.

    Could the symptom be recreated? 

    Yes No
    Key in OFF position. Key in OFF position.
    GO to  TU8. GO to Pinpoint Test Z .
  8. TU8 CHECK THE TCM TOTAL TORQUE DESIRED PID VALUE IN REVERSE 
    NOTE: Use the data recorded in the Pinpoint Test Step TU7.

    Does the TCM TQ_DSD PID display between -4,000 - 0 Nm (-2,950 - 0 lb-ft) when the symptom occurs? 

    Yes No
    GO to  TU9. GO to  TU11.
  9. TU9 CHECK THE TCM TOTAL TORQUE DESIRED PID VALUE IN DRIVE 
    NOTE: Use the data recorded in the Pinpoint Test Step TU7.

    Does the TCM TQ_DSD PID display between 0 - 4,000 Nm (0 - 2,950 lb-ft) when the symptom occurs? 

    Yes No
    INSTALL a new transaxle assembly. GO to  TU11.
  10. TU10 CHECK THE TCM TOTAL TORQUE DESIRED PID VALUE IN LOW 
    NOTE: Use the data recorded in the Pinpoint Test Step TU7.

    Does the TCM TQ_DSD PID display between 0 - 4,000 Nm (0 - 2,950 lb-ft) when the symptom occurs? 

    Yes No
    GO to  TU10. GO to  TU11.
  11. TU11 CHECK FOR CORRECT PCM OPERATION 
    • Disconnect all the PCM connectors.
    • Visually inspect for:
      • pushed out pins.
    • corrosion.
    • Connect all the PCM connectors and make sure they seat correctly.
    • Carry out the PCM self-test and verify the concern is still present.

    Is the concern still present? 

    Yes No
    INSTALL a new PCM. REFER to FLASH ELECTRICALLY ERASABLE PROGRAMMABLE READ ONLY MEMORY (EEPROM) . The system is operating correctly at this time. The concern may have been caused by a loose or corroded connector.
