NG >> Check power supply circuit and 15A fuses [Nos. 15 and 17, located in the fuse block (J/B)].
Refer to PG-3, "
Schematic".
• If fuses are OK, reinstall fuses and GO TO 3.
• If fuses are NG, replace fuse and check harness for short circuit. Repair or replace if necessary.
3.CHECK BLOWER MOTOR RELAY POWER SUPPLY CIRCUITS
1. Turn ignition switch OFF.
2. Disconnect blower motor relay connector.
3. Turn ignition switch ON.
4. Check voltage between blower motor relay harness connector J-
1 terminal 1, 5 and ground.
OK or NG
OK >> GO TO 4.
NG >> Repair harness or connector.
4.CHECK BLOWER MOTOR RELAY (SWITCH SIDE) CIRCUIT FOR OPEN
1. Turn ignition switch OFF.
2. Check continuity between blower motor relay harness connector
J-1 (A) terminal 3 and front blower motor harness connector
M62 (B) terminal 1.
OK or NG
OK >> GO TO 5.
NG >> Repair harness or connector.
5.CHECK BLOWER MOTOR RELAY GROUND CIRCUIT
Check continuity between blower motor relay harness connector J-1
terminal 2 and ground.
OK or NG
OK >> Replace blower motor relay.
NG >> Repair harness or connector.
6.CHECK FRONT BLOWER MOTOR
Check continuity between front blower motor terminals 1 and 2.
NOTE:
Ensure that there are no foreign particles inside the A/C unit assem-
bly for a smooth rotation of the front blower motor.
OK or NG
OK >> GO TO 7.
NG >> Replace front blower motor. Refer to MTC-62, "

CAUTION:
• Do not use electrical test equipment on any circuit related to the SRS unless instructed to do so in
this Service Manual.
• Do not attempt to repair, splice or modify SRS wiring harnesses. If a harness is damaged, replace it
with a new one.
• Keep ground connections clean.
DIAGNOSIS FUNCTION
The SRS self-diagnosis results can be read by using “AIR BAG” warning lamp and/or CONSULT-III.
The User mode is exclusively prepared for the customer (driver). This mode warns the driver of a system mal-
function through the operation of the “AIR BAG” warning lamp.
The Diagnosis mode allows the technician to locate and inspect the malfunctioning part.
The mode applications for the “AIR BAG” warning lamp and CONSULT-III are as follows:
HOW TO PERFORM TROUBLE DIAGNOSES FOR QUICK AND ACCURATE REPAIR
A good understanding of the malfunction conditions can make troubleshooting faster and more accurate.
In general, each customer feels differently about a malfunction. It is important to fully understand the symp-
toms or conditions for a customer complaint.
