Normal Operation
Under normal operation, to rotate the air inlet door actuator, the EMTC module or EATC 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 EATC module reverses the voltage and ground circuits.

Possible Causes
- An open, short to voltage, ground or together in circuits CH207 (BU/GY) or CH208 (GN/OG)
- Air inlet door actuator motor
- EATC module
- EMTC module
- Stuck or bound linkage or door
