Theory of Operation
The A/C Heater Control drives the Driver Blend Door Actuator via the (C61) Blend Door Driver circuit and the (C34)
Common Door Driver circuit. The A/C Heater Control drives the Passenger Blend Door Actuator via the (C33) Pas-
senger Blend Door Driver circuit and the (C34) Common Door Driver circuit.The A/C Heater Control drives the
Mode Door 1 (Panel to Floor) Actuator via the (C29) Mode Door 1 Driver circuit and the (C34) Common Door Driver
circuit. The A/C Heater Control drives the Mode Door 2 (Defrost to Floor) Actuator via the (C801) Mode Door 2
Driver circuit and the (C34) Common Door Driver circuit. The A/C Heater Control drives the Recirculation Door
Actuator via the (C32) Recirculation Door Driver circuit and the (C34) Common Door Driver circuit. All of the door
actuators share the (C34) Common Door Driver circuit. Inside the A/C Heater Control, each door actuator has its
own unique driver, but all share a single common door driver circuit. Due tothesharedcircuitrysimilarDTCscan
set at the same time for multiple actuators depending upon the type of short, its location, and the direction the
actuator is moving when the short is present.
When Monitored:
When the Actuator DTC Detection Test is executed.
Set Condition:
If the (C34) Common Door Driver circuit is shorted to voltage.
Possible Causes
