Detection Condition

PCM monitors Variable Air Duct (VAD) control solenoid control signal at PCM 30-pin harness connector terminal "4C". If PCM detects VAD control solenoid control signal does not change when VAD control solenoid valve is switched to ON or OFF, PCM determines VAD control solenoid control circuit has malfunction. This is a Continuous Monitor (other). MIL does not comes on. PENDING CODE is available if PCM detects malfunction condition. FREEZE FRAME DATA is available. DTC is stored in PCM memory.
