Toyota Sienna Service Manual: Air Outlet Damper Control Servo Motor Circuit

DESCRIPTION

This circuit turns the servo motor and changes each damper position by receiving the signals from the A/ C amplifier.

The air outlet damper servo motor switches the air outlet mode by rotating (normal, reverse) with electrical power from the A/C amplifier.

When the AUTO switch is on, the A/C amplifier changes the mode between "FACE", "FACE/FOOT" and "FOOT" according to the temperature setting.

INSPECTION PROCEDURE

1 READ VALUE OF INTELLIGENT TESTER

(a) Connect the intelligent tester to the DLC3.

(b) Turn the ignition switch to the ON position and turn the intelligent tester main switch on.

(c) Select the items below in the DATA LIST, and read the display on the intelligent tester.

DATA LIST / AIR CONDITIONER

OK: When the target position is "FACE" (0%), the actual opening angle is 19.0% or less.

When the target position is "DEF" (100%), the actual opening angle is 81.0% or more.

4 INSPECT AIR OUTLET CONTROL SERVO MOTOR

 INSPECT AIR OUTLET CONTROL SERVO MOTOR

(a) Remove the air outlet control servo motor.

(b) Disconnect the connector from the air outlet control servo motor.

(c) Connect the positive (+) lead from the battery to terminal 4 and the negative (-) lead to terminal 5, then check that the lever turns to the "DEF" position smoothly.

OK: Lever turns to "DEF" position smoothly.

(d) Connect the positive (+) lead from the battery to terminal 5 and the negative (-) lead to terminal 4, then check that the lever turn to the "FACE" position smoothly.

OK: Lever turns to "FACE" position smoothly.

5 CHECK HARNESS AND CONNECTOR (AIR OUTLET CONTROL SERVO MOTOR - A/C AMPLIFIER)

CHECK HARNESS AND CONNECTOR (AIR OUTLET CONTROL SERVO MOTOR - A/C AMPLIFIER)
