Diagnostic Test

  1. CHECK IF THE DTC IS ACTIVE 
    1. With the scan tool, read Transmission DTCs.

      Is the status Active or is the Starts Since Set counter 2 or less for this DTC?

      Yes 

      • Go To  2.

      No 

      • Go To  6.
  2. CHECK TO SEE IF THE DTC IS ACTIVE

    1. Turn the ignition off to the lock position.
    2. Disconnect the Transmission Solenoid/Pressure Switch Assembly harness connector.
    3. Ignition on, engine not running.
    4. With the scan tool actuate the TCC ON/OFF Solenoid.
    5. Using a 12-volt test light connected to ground, check the (T60) TCC ON/OFF Solenoid Control circuit.
      NOTE:

      The test light must illuminate brightly. Compare the brightness to that of a direct connection to the battery.

      Does the test light illuminate brightly?

      Yes 

      • Go To  3.

      No 

      • Go To  4.
  3. CHECK THE (T60) TCC ON/OFF SOLENOID CONTROL CIRCUIT FOR A SHORT TO VOLTAGE

    1. Turn the ignition off to the lock position.
    2. Disconnect the TCM C1 harness connector.
    3. Ignition on, engine not running.
    4. Measure the voltage of the (T60) TCC ON/OFF Solenoid Control circuit.

      Is the voltage above.05 of a volt?

      Yes 

      • Repair the (T60) TCC ON/OFF Solenoid Control circuit for a short to voltage.
      • Perform the CVT VERIFICATION TEST. Refer to Standard Procedure .

      No 

      • Replace the Valve Body in accordance with the Service Information.
      • Perform the CVT VERIFICATION TEST. Refer to Standard Procedure .
  4. CHECK THE (T60) TCC ON/OFF SOLENOID CONTROL CIRCUIT FOR AN OPEN

    1. Turn the ignition off to the lock position.
    2. Measure the resistance of the (T60) TCC ON/OFF Solenoid Control circuit between the TCM C1 harness connector and the Transmission Solenoid/Pressure Switch Assembly harness connector.

      Is the resistance above 5.0 Ohms?

      Yes 

      • Repair the (T60) TCC ON/OFF Solenoid Control circuit for an open.
      • Perform the CVT VERIFICATION TEST. Refer to Standard Procedure .

      No 

      • Go To  5.
  5. CHECK THE (T60) TCC ON/OFF SOLENOID CONTROL CIRCUIT FOR A SHORT TO GROUND 
    Fig 4: Measuring Resistance Between Ground & TCC ON/OFF Solenoid Control Circuit

    1. Measure the resistance between ground and the (T60) TCC ON/OFF Solenoid Control circuit.

      Is the resistance below 5.0 Ohms?

      Yes 

      • Repair the (T60) TCC ON/OFF Solenoid Control circuit for a short to ground.
      • Perform the CVT VERIFICATION TEST. Refer to Standard Procedure .

      No 

      • Using the schematics as a guide, check the Transmission Control Module (TCM) terminals for corrosion, damage, or terminal push out. Pay particular attention to all power and ground circuits. Check for any Service Bulletins for possible causes that may apply. If no problems are found, replace the TCM in accordance with the Service Information.
      • Perform the CVT VERIFICATION TEST. Refer to Standard Procedure .
  6. CHECK THE WIRING AND CONNECTORS 
    1. The conditions necessary to set this DTC are not present at this time.
    2. Using the schematics as a guide, inspect the wiring and connectors specific to this circuit.
    3. Wiggle the wires while checking for shorted and open circuits.

      Were there any problems found?

      Yes 

      No 

      • Test Complete.
