Toyota RAV4 (XA40) 2013-2018 Service Manual: Air outlet damper control servo motor circuit

Toyota RAV4. Air outlet damper control servo motor circuit


Description

The damper servo 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 mode damper to the appropriate position, which controls the air outlet modes.

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 (air out pulse)

  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.

  1. Replace mode 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.

If the vehicle is submerged or water on the road is rising
This vehicle is not designed to be able to drive on roads that are deeply flooded with water. Do not drive on roads where the roads may be submerged or the water may be rising. It is dangerous to remain in the vehicle, if it is anticipated that the vehicle will be flooded or set adrift. Remain calm ...

Fail-safe chart
Fail safe operation If there is a problem with any sensor signals or actuator systems, the skid control ecu prohibits the power supply to the abs and traction actuator and informs the ecm of vsc system failure. The abs and traction actuator turns off the solenoids and the ecm sh ...
