For a complete wiring diagramRefer to Section 8W.
Theory of Operation
The A/C Heater Control drives the Blend Door Actuator via the (C61) Blend Door Driver circuit and the (C34) Com-
mon 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)CommonDoorDrivercircuit.TheA/CHeater Control drives the Mode
Door 2 (Defrost to Floor) Actuator via the (C801) Mode Door 2 Driver circuitand 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 to the shared circuitry similar DTCs can set at the sametime 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 ground.
Possible Causes
(C34) COMMON DOOR DRIVER CIRCUIT SHORTED TO GROUND
(C34) COMMON DOOR DRIVER CIRCUIT SHORTED TO OTHER DOOR DRIVER CIRCUIT(S)
BLEND DOOR ACTUATOR
MODE DOOR 1 (PANEL TO FLOOR) ACTUATOR
MODE DOOR 2 (DEFROST TO FLOOR) ACTUATOR
RECIRCULATION DOOR ACTUATOR
A/C HEATER CONTROL
Diagnostic Test
1.CHECK (C34) COMMON DOOR DRIVER CIRCUIT FOR A SHORT TO GROUND
Turn the ignition off.
Disconnect the A/C Heater Control C1 harness connector.
Measure the resistance of the (C34) Common Door Driver circuit
between ground and the A/C Heater Control C1 harness connector.
