MAGNET CLUTCH

Description

INFOID:0000000001069976

Magnet clutch drives a compressor, by a signal of IPDM E/R.

Component Function Check

INFOID:0000000001069977

1.

CONFIRM SYMPTOM BY PERFORMING THE FOLLOWING OPERATIONAL CHECK

1.

Turn fan control dial to the desired (1 to 4 speed) position.

2.

Press A/C switch.

3.

A/C switch indicator will turn ON. Confirm that the magnet clutch engages (sound or visual inspection).

Does the magnet clutch operate?

YES

>> END.

NO

>> Go to Diagnosis Procedure. Refer to 

HAC-157, "Diagnosis Procedure"

.

Diagnosis Procedure

INFOID:0000000001069978

1.

PERFORM AUTO ACTIVE TEST

Perform “AUTO ACTIVE TEST”. Refer to 

PCS-9, "Diagnosis Description"

.

Does the magnet clutch operate?

YES

>> •

WITH CONSULT-III: GO TO 5.

•

WITHOUT CONSULT-III: GO TO 6.

NO

>> Check 10A fuse (No. 53, located in IPDM E/R), and GO TO 2.

2.

CHECK CIRCUIT CONTINUITY BETWEEN IPDM E/R AND COMPRESSOR

1.

Turn ignition switch OFF.

2.

Disconnect IPDM E/R connector and compressor connector.

3.

Check continuity between IPDM E/R harness connector E12 terminal 23 and compressor harness con-
nector F17 (With Gasoline Engine) or F18 (With Diesel Engine) terminal 1.

With Gasoline Engine

With Diesel Engine

Is the inspection result normal?

YES

>> GO TO 3.

NO

>> Repair harness or connector.

3.

CHECK CIRCUIT CONTINUITY BETWEEN COMPRESSOR GROUND

1.

Turn ignition switch OFF.

2.

Check continuity between compressor harness connector F17 (With Gasoline Engine) or F18 (With Diesel
Engine) terminal 2 and ground.

MAGNET CLUTCH

With Diesel Engine

Is the inspection result normal?

YES

>> GO TO 4.

NO

>> Repair harness or connector.

4.

CHECK MAGNET CLUTCH CIRCUIT

Check for operation sound when applying battery voltage direct current to terminal.
Is the inspection result normal?

YES

>> Replace IPDM E/R.

NO

>> Replace compressor.

5.

CHECK BCM INPUT (AIR COND SW) SIGNAL

Check compressor ON/OFF signal in “DATA MONITOR”. Refer to 

HAC-140, "AIR CONDITIONER : CON-

SULT-III Function (BCM - MANUAL AIR CONDITIONER)"

.

Is the inspection result normal?

YES

>> GO TO 8.

NO

>> GO TO 6.

6.

CHECK CIRCUIT CONTINUITY BETWEEN HEATER CONTROL PANEL AND BCM

1.

Turn ignition switch OFF.

2.

Disconnect heater control panel connector and BCM harness connector.

3.

Check continuity between heater control panel harness connector M54 terminal 7 and BCM harness con-
nector M65 terminal 14.

Is the inspection result normal?

YES

>> GO TO 7.

NO

>> Repair harness or connector.

7.

CHECK A/C SWITCH SIGNAL

1.

Turn ignition switch OFF.

2.

Disconnect heater control panel connector.

3.

Turn ignition switch ON.

4.

Check voltage between heater control panel harness connector M54 terminal 7 and ground.

5.

Reonnect heater control panel connector.

6.

Press A/C switch and turn fan control dial except OFF position.

7.

Check voltage between heater control panel harness connector M54 terminal 7 and ground.
