DESCRIPTION

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

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

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 "FACE1" (0%), the actual opening angle is 19.0% or less.

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

2 PERFORM ACTIVE TEST BY 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 item below in the ACTIVE TEST and then check the air flow position by hand.

ACTIVE TEST / AIR CONDITIONER

OK: Air comes out from the selected air outlet.

4 INSPECT REAR AIR OUTLET CONTROL SERVO MOTOR

INSPECT REAR AIR OUTLET CONTROL SERVO MOTOR

(a) Remove the rear air outlet control servo motor.

(b) Disconnect the connector from the rear 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 "FOOT" position smoothly.

OK: Lever turns to "FOOT" position smoothly.

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

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

(a) Disconnect the connector from the A/C amplifier.

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

(b) Measure the resistance according to the value(s) in the table below.

Standard resistance
