TROUBLE DIAGNOSIS
OK or NG
OK >> • GO TO 18 (with CVT).• GO TO 19 (without CVT).
NG >> GO TO 21.
18.CHECK THERMO CONTROL AMP. GROUND CIRCUIT
1. Turn ignition switch OFF.
2. Check continuity between thermo control amp. harness connec- tor M42 terminal 2 and ground.
OK or NG
OK >> Repair thermo control amp. jumper as necessary.
NG >> Repair harness or connector.
19.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 20.
NG >> Check power supply circuit and 10A fuse [No. 16, located in the fuse block (JB)]. Refer to PG-73
.
• 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.
20.CHECK THERMO CONTROL AMP. GROUND CIRCUIT
1. Turn ignition switch OFF.
2. Check continuity between thermo control amp. harness connec- tor M42 terminal 2 and ground.
OK or NG
OK >> Replace thermo control amp. Refer to MTC-58,
"Removal and Installation".
NG >> Repair harness or connector.
21.CHECK CIRCUIT CONTINUITY BETWEEN THERMO CONTROL AMP. AND BCM
