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. TI1 DTC P1A08: CHECK FOR SELF-TEST DTCS 

    Is TCM DTC P1A08 present during the self-test? 

    Yes No
    For KOEO DTC P1A08, GO to  TI3. Unable to duplicate or identify the fault at this time.
    For continuous memory DTC P1A08, GO to  TI2. The concern is elsewhere. RETURN to SYMPTOM CHARTS for further direction.
  2. TI2 CONTINUOUS MEMORY DTC P1A08: CLEAR AND RETRIEVE TCM CONTINUOUS DTCS 
    NOTE: Diagnose and repair any PCM and TCM KOEO and KOER self-test DTCs before entering this pinpoint test.
    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.
    • Record and clear the PCM and TCM continuous DTCs.
    • Clear and retrieve TCM continuous DTCs.

    Is TCM continuous DTC P1A08 present during the self-test? 

    Yes No
    GO to  TI3. Unable to duplicate or identify the fault at this time.
    DISREGARD the current diagnostic trouble code (DTC) at this time. DIAGNOSE the next DTC. GO to DIAGNOSTIC TROUBLE CODE (DTC) CHARTS AND DESCRIPTIONS .
  3. TI3 KOEO DTC P1A08: CHECK THE TCM GENERATOR MODE PID 
    • Key ON, engine OFF.
    • Access the TCM and monitor the GENMODE PID.
    • Key ON, engine running.

    Does the PID indicate that the GENMODE changed when the key is cycled from RUN to START? 

    Yes No
    Key in OFF position. INSTALL a new transaxle assembly. Key in OFF position.
    GO to  TI4.
  4. TI4 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.
