Diagnostic Procedure

WARNING: This page is about a different variant/trim than selected.
  1. INSPECTION START 

    Do you have CONSULT-II? 

    Yes or No

    1. Yes: GO TO 2.
    2. No: GO TO  6.
  2. CHECK INPUT SIGNAL OF A/T FLUID TEMPERATURE SENSOR (WITH CONSULT-II) 

    With CONSULT-II 

    1. Start engine.
    2. Select "TCM INPUT SIGNALS" in "DATA MONITOR" mode for "A/T" with CONSULT-II.
    3. Read out the value of "FLUID TEMP SE".

      Voltage :Cold [20°C (68°F)] --> Hot [80°C (176°F)] 

      :Approximately 1.5V --> 0.5V 

    OK or NG

    1. OK: GO TO  7.
    2. NG: GO TO 3.

  3. CHECK A/T FLUID TEMPERATURE SENSOR WITH TERMINAL CORD ASSEMBLY 
    1. Turn ignition switch to OFF position.
    2. Disconnect terminal cord assembly connector in engine compartment.
    3. Check resistance between terminal cord F30 terminals 6 and 7 (component side) when A/T is cold.

  4. DETECT MALFUNCTIONING ITEM 

    Check the following items:

    • Harness for short to ground or short to power or open between TCM, ECM and terminal cord assembly (Main harness)
    • Ground circuit for ECM

      Refer to "POWER SUPPLY ROUTING CIRCUIT ".

    OK or NG

    1. OK: GO TO  7.
    2. NG: Repair or replace damaged parts.
  5. DETECT MALFUNCTIONING ITEM 
    1. Remove oil pan.
    2. Check the following items:
      • A/T fluid temperature sensor

        Check resistance between two terminals while changing temperature as shown in figure.

  7. CHECK DTC 

    Perform "DIAGNOSTIC TROUBLE CODE (DTC) CONFIRMATION PROCEDURE ".

    OK or NG

    1. OK: INSPECTION END 
    2. NG: GO TO 8.
  8. CHECK TCM INSPECTION 
    1. Perform TCM input/output signal inspection.
    2. If NG, recheck TCM pin terminals for damage or loose connection with harness connector.

    OK or NG

    1. OK: INSPECTION END 
    2. NG: Repair or replace damaged parts.
