Toyota RAV4 Service Manual: Air inlet damper control servo motor circuit

Toyota RAV4. Air inlet damper control servo motor circuit


Description

The damper servo (air inlet control) sends pulse signals to indicate the damper position to the air conditioning amplifier. The air conditioning amplifier activates the motor (normal or reverse) based on these signals to move the air inlet control damper to the appropriate position, which controls the intake air settings (fresh, fresh / recirculation and recirculation).

Hint:

Confirm that there are no mechanical problems because this dtc can be output when either a damper link or damper is mechanically locked.
