4. CHECK THE (T16) TRANSMISSION CONTROL OUTPUT CIRCUIT FOR AN OPEN Turn the ignition off to the lock position. Connect the TIPM C8 harness connector. Disconnect the Transmission Solenoid/Pressure Switch Assembly harness connector. Ignition on, engine not running. Using the scan tool under the TIPM Actuators, actuate the Transmission. Using a 12-volt test light connected to ground, check the (T16) Transmission Control Output circuits. NOTE: The test light must illuminate brightly. Compare the brightness to that of a direct connection to the Does the test light illuminate brightly at all the (T16) Transmission Control Output circuits? Yes >> Go To 5 No >> Repair the (T16) Transmission Control Output circuit for an open. Perform CVT VERIFICATION TEST. (Refer to 21 - TRANSMISSION/TRANSAXLE/AUTOMATIC - CVT - 5. TOTALLY INTEGRATED POWER MODULE Using the schematics as a guide, inspect the wire harness and connectors. Check the TIPM harness connector terminals for corrosion, damage, or terminal push out. Pay particular attention to all power and ground circuits. Were any problems found? Yes >> Repair as necessary. Perform CVT VERIFICATION TEST. (Refer to 21 - TRANSMISSION/TRANSAXLE/AUTOMATIC - CVT - No >> Replace and program the TIPM per Service Information. Perform CVT VERIFICATION TEST. (Refer to 21 - TRANSMISSION/TRANSAXLE/AUTOMATIC - CVT - 6. INTERMITTENT WIRING AND CONNECTORS The conditions necessary to set this DTC are not present at this time. Using the wiring diagram/schematic as a guide, inspect the wiring and connectors. While monitoring the scan tool data relative to this circuit, wiggle test the wiring and connectors. Look for the data to change or for the DTC to reset during the wiggle test. Were any problems found? Yes >> Repair as necessary. Perform CVT VERIFICATION TEST. (Refer to 21 - TRANSMISSION/TRANSAXLE/AUTOMATIC - CVT - No >> Test complete. PM AUTOMATIC - CVT-ELECTRICAL DIAGNOSTICS 21 - 111 |
