Toyota RAV4 (XA40) 2013-2018 Service Manual: Air mix damper control servo motor circuit (passenger side)
Description
The air mix 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 air mix damper (passenger seat) to the appropriate position. This adjusts the amount of air passing through the heater core after passing the evaporator and controls the temperature of the blown air
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
- Read value of intelligent tester (air mix pulse-p)
- Connect the intelligent tester (with can vim) to the dlc3.
- Turn the ignition switch on and turn the intelligent tester main switch on.
- 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.
- Replace air mix control servo motor
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.
System is ok

System check
Hint:
Performing a system check enables the system,
which consists of multiple actuators, to be operated
without removing any parts. In addition, it can show
whether or not any dtcs are set, and can detect
potential malfunctions in the system. The system
check can be performed with the intelli ...
Check mode procedure
Description
Check mode has a higher sensitivity to malfunctions
and can detect malfunctions that normal mode
cannot detect. Check mode can also detect all the
malfunctions that normal mode can detect. In check
mode, dtcs are detected with 1 trip detection logic.
