Diagnostic Test

WARNING: This page is about a different variant/trim than selected.
  1. CHECK RESISTANCE VALUE OF TRANSMISSION OIL TEMPERATURE SENSOR 
    1. 6.445 kilohms at the transmission oil temperature of 10°C (50°F)
    2. 3.5 kilohms at the transmission oil temperature of 25°C (77°F)
    3. 0.247 kilohms at the transmission oil temperature of 110°C (230°F)

      Are the measured resistance values as described?

      Yes 

      • Go to Step.  2.

      No 

      • Go to Step. 3.
  2. CHECK TRANSMISSION CONTROL MODULE (TCM) WIRING 
    1. Go to Key-OFF status.
    2. Disconnect connector B of the Transmission Control Module (TCM).
    3. Check whether the terminals of the transmission oil temperature sensor on Transmission Control Module (TCM) (J and M of connector B) are disconnected, damaged or corroded.

      Are terminals disconnected, damaged or corroded?

      Yes 

      • Repair or replace the connector or the terminals.
      • Go to Step.  5.

      No 

      • Go to Step.  3.
  3. CHECK TRANSMISSION OIL TEMPERATURE SENSOR WIRING 
    1. Check for the presence of an open circuit on the wiring between the and Transmission Control Module (TCM) (PIN J and M of connector B).

      Is there an open circuit?

      Yes 

      • Remove the open circuit on the wiring.
      • Go to Step.  5.

      No 

      • Go to Step.  4.
  4. CHECK CORRECT OPERATION OF TRANSMISSION OIL TEMPERATURE SENSOR 
    1. Connect the diagnosis equipment to the Transmission Control Module (TCM) and check correct operation of the transmission oil sensor.

      Is the transmission oil temperature sensor working properly?

      Yes 

      • Go to Step.  5.

      No 

      • Replace the solenoid valve assembly.
      • Go to Step.  5.
  5. CHECK CORRECT OPERATION OF TRANSMISSION CONTROL MODULE (TCM) 
    1. Perform the Transmission Control Module (TCM) error deletion procedure.
    2. Start the engine.
    3. Heat engine and gearbox.
    4. Drive the vehicle with automatic transmission selector in D position and ensure that the gear is shifted from the first to the sixth.
    5. Check whether there is a fault.

      Is the error still present?

      Yes 

      No 

      • End of diagnosis.
