SYSTEM DESCRIPTION
Thermo control amp. controls A/C compressor operation by intake air temperature and signal from ECM.
The defrost A/C switch controls A/C compressor operation by the BCM when the mode switch is turned to the
(DEF) position.
Low Temperature Protection Control
When intake air temperatures are higher than 4°C (39°F), the com-
pressor turns ON. The compressor turns OFF when intake air tem-
peratures are lower than 2°C (36°F).
DIAGNOSTIC PROCEDURE FOR MAGNET CLUTCH
SYMPTOM: Magnet clutch does not engage in A/C, defrost/foot, or defrost mode.
1. PERFORM AUTO ACTIVE TEST
Refer to PG-21, "
Auto Active Test" .
Does the magnet clutch operate?
YES >> GO TO 5.
NO >> Check 10A fuse (No. 42, located in the IPDM E/R). Refer to PG-24, "
IPDM E/R Terminal Arrange-
ment" .

If fuse is OK, GO TO 2.

If fuse is NG, replace fuse and check harness for short circuit. Repair or replace if necessary.
2. CHECK POWER SUPPLY FOR IPDM E/R
Check power supply to 10A fuse (No. 42 located in the IPDM E/R).
OK or NG
OK >> GO TO 3.
NG >> Check harness for open circuit. Repair or replace if necessary.

3. CHECK POWER SUPPLY FOR A/C COMPRESSOR
1. Disconnect A/C compressor connector.
2. Start the engine.
3. Turn blower control dial and A/C switch ON.
4. Check voltage between A/C compressor harness connector F3
terminal 1 and ground.
OK or NG
OK >> Replace magnet clutch. Refer to MTC-84, "Removal and
Installation of Compressor"
NG >> GO TO 4.
4. CHECK CIRCUIT CONTINUITY BETWEEN IPDM E/R AND COMPRESSOR
1. Turn ignition switch OFF.
2. Disconnect IPDM E/R connector.
3. Check continuity between A/C compressor harness connector
F3 (A) terminal 1 and IPDM E/R harness connector E43 (B) ter-
minal 11.
OK or NG
OK >> Replace IPDM E/R. Refer to PG-29, "Removal and
Installation of IPDM E/R"
NG >> Repair harness or connector.
5. CHECK DEFROST A/C SWITCH
1. Start the engine.
2. Turn the mode control dial to (DEF) position.
Does the magnet clutch operate
OK >> GO TO 6.
NG >> GO TO 22.
6. CHECK BCM INPUT (COMPRESSOR ON) SIGNAL
1. Turn ignition switch OFF.
2. Check compressor ON/OFF signal. Refer to MTC-24, "
CON-
SULT-II Function (BCM)" .
OK or NG
OK >> GO TO 8.
NG >> GO TO 7.1 - Ground :Battery voltage

16. CHECK FRONT AIR CONTROL GROUND CIRCUIT
Check continuity between front air control harness connector M33
terminal 8 and ground.
OK or NG
OK >> GO TO 17.
NG >> Repair harness or connector.
17. CHECK POWER SUPPLY FOR THERMO CONTROL AMP.
1. Turn ignition switch OFF.
2. Disconnect thermo control amp. connector.
3. Turn ignition switch ON.
4. Confirm thermo amp signal between thermo control amp. har-
ness connector M42 terminal 3 and ground using oscilloscope.
OK or NG
OK >> GO TO 18.
NG >> GO TO 20.
18. CHECK POWER SUPPLY FOR THERMO CONTROL AMP.
Check voltage between thermo control amp. harness connector M42
terminal 1 and ground.
OK or NG
OK >> GO TO 19.
NG >> Check power supply circuit and 10A fuse [No. 16,
located in the fuse block (JB)]. Refer to PG-76, "
FUSE
BLOCK-JUNCTION BOX (J/B)" .

If fuse is OK, check harness for open circuit. Repair or
replace if necessary.

If fuse is NG, replace fuse and check harness for
short circuit. Repair or replace if necessary. 8 - Ground :Continuity should exist
