Theory of Operation The Transmission Control Module (TCM) monitors the TCC ON/OFF Solenoid Control signal during normal opera- • When Monitored: • Set Condition: Possible Causes (T60) TCC ON/OFF SOLENOID CONTROL CIRCUIT SHORT TO VOLTAGE (T60) TCC ON/OFF SOLENOID CONTROL CIRCUIT OPEN (T60) TCC ON/OFF SOLENOID CONTROL CIRCUIT SHORT TO GROUND TCC ON/OFF SOLENOID TRANSMISSION CONTROL MODULE Always perform the CVT Pre-Diagnostic Troubleshooting procedure before proceeding. (Refer to 21 - Diagnostic Test 1. CHECK IF THE DTC IS ACTIVE With the scan tool, read Transmission DTCs. Is the status Active for this DTC or is the STARTS SINCE SET counter 2 or less? Yes >> Go To 2 No >> Go To 6 2. CHECK TO SEE IF THE DTC IS ACTIVE Turn the ignition off to the lock position. Disconnect the Transmission Solenoid/Pressure Switch Assembly harness connector. Ignition on, engine not running. With the scan tool actuate the TCC ON/OFF Solenoid. 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 Does the test light illuminate brightly? Yes >> Go To 3 No >> Go To 4 PM AUTOMATIC - CVT-ELECTRICAL DIAGNOSTICS 21 - 243 |
