Component Inspection

  1. CHECK "TRANSAXLE FLUID TEMPERATURE SENSOR"
    1. Ignition "OFF".
    2. Disconnect the "TRANSAXLE FLUID TEMPERATURE SENSOR" connector.
    3. Measure the resistance between terminals "1" and "2" of the "TRANSMISSION FLUID TEMPERATURE SENSOR".

      Specification: Refer to table below "Reference data".

    4. Is resistance within specifications?

      YES  : --> "CHECK PCM/TCM" go to  2 below.

      NO  : --> Replace "TRANSAXLE FLUID TEMPERATURE SENSOR" as necessary and Go to "VERIFICATION OF VEHICLE REPAIR " procedure.

  2. CHECK TCM
    1. Ignition "ON" & Engine "OFF".
    2. Connect "TRANSAXLE FLUID TEMPERATURE SENSOR" connector.
    3. Install scantool and select a SIMU-SCAN.
    4. Simulate voltage (0-->5V) to "TRANSMISSION FLUID TEMPERATURE SENSOR" signal circuit.

      * The values are subject to change according to vehicle model

    5. Is FLUID TEMP. SENSOR signal value changed according to simulation voltage?

      YES  : --> Thoroughly check connectors for looseness, poor connection, bending, corrosion, contamination, deterioration, or damage. Repair or replace as necessary and then go to "VERIFICATION OF VEHICLE REPAIR " procedure.

      NO  : --> Substitute with a known-good PCM/TCM and check for proper operation. If the problem is corrected, replace PCM/TCM as necessary and then go to "VERIFICATION OF VEHICLE REPAIR " procedure.
