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.

Inspection procedure

  1. Read value of intelligent tester (a/i damp targ pls)

  1. Connect the intelligent tester (with can vim) to the dlc3.
  2. Turn the ignition switch on and turn the intelligent tester main switch on.
  3. Select the items below in the data list, and read the value displayed on the intelligent tester.


Ok: the display is as specified in the normal condition column.

  1. Replace damper servo sub-assembly

Hint:

Since the servo motor cannot be tested when it is removed from the vehicle, replace the servo motor with a normal one and check that the condition returns to normal.

Ok: same problem does not occur.

Throttle actuator control motor current range / performance
Description The etcs (electronic throttle control system) has a dedicated power supply circuit. The voltage (+bm) is monitored and when it is low (less than 4 v), the ecm determines that there is a malfunction in the etcs and cuts off the current to the throttle actuator. When the volt ...
