COMMON DRIVER SHORTED TO GROUND (MTC)





For a complete wiring diagram Consult Diagrams/Electrical

- When Monitored:
When the Actuator Circuit Test is executed.

- Set Condition:
This message will set if the A/C Heater Control detects a short low on the Common Door Driver circuit.





1. ACTIVE HVAC DTC(S) PRESENT
Turn the ignition on.
Using the scan tool, clear all HVAC DTC's.

Measure the resistance between ground and the (C34) Common Door Driver circuit.
Does the ohm meter ready open circuit?

Yes

- Replace the A/C Heater Control.
- Perform the BODY VERIFICATION TEST - VER 1. Body Verification Test.

No

- Repair the (C34) Common Door Driver circuit for a short to ground.
