Test E: Air Inlet Door Is Inoperative
PINPOINT TEST E: AIR INLET DOOR IS INOPERATIVENormal Operation
Under normal operation, to rotate the air inlet door actuator, the HVAC module supplies voltage to the air inlet door actuator motor through circuit CH208 (GN/OG), and supplies ground through circuit CH207 (BU/GY). To reverse the air inlet door actuator rotation, the HVAC module reverses the voltage and ground circuits.
This pinpoint test is intended to diagnose the following:
- Wiring, terminals or connectors
- Air inlet door actuator motor
- HVAC module - EATC
- HVAC module - DATC
- HVAC module - EMTC
- Stuck or bound linkage or door
