Magnet Clutch
DIAGNOSTIC PROCEDURE
Except for KA engine models
SYMPTOM: Magnet clutch does not engage when A/C
switch and fan switch are ON.
CHECK POWER SUPPLY FOR COM-
PRESSOR.
Disconnect compressor harness connec-
tor.
Do approx. 12 volts exist between com-
pressor harness terminal No.
V1and body
ground?
No
cYes
Check the following.
lMagnet clutch coillThermal protector (Except
for the Middle East)
NG
Replace magnet clutch.
Refer to HA-69 in D22
SERVICE MANUAL, Publi-
cation No. SM7E-0D22G1.
Note
Check circuit continuity between A/C relay
harness terminal No.
V5and compressor
harness terminal No.
V1.
Continuity should exist.
If OK, check harness for short.
OK
CHECK POWER SUPPLY FOR A/C
RELAY.
Do approx. 12 volts exist between A/C
relay harness terminal Nos.
V1,V3and
body ground?
Yes
cNo
Check power supply circuit
and 7.5A fuse (No.
23,
located in the fuse block).
(Refer to ªPOWER SUP-
PLY ROUTINGº in EL sec-
tion and Wiring Diagram.)
CHECK A/C RELAY AFTER DISCON-
NECTING IT.
Refer to HA-2021.
OK
cNG
Replace A/C relay.
TD25 and TD25Ti engines
Reconnect A/C relay.
