TROUBLE DIAGNOSISPFP:00004
Trouble Diagnosis IntroductionBHS00043
CAUTION:

Do not use electrical test equipment on any circuit related to the SRS unless instructed to in this
Service Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or
harness connectors.

Do not attempt to repair, splice or modify the SRS wiring harness. If the harness is damaged,
replace it with a new one.

Keep ground portion clean.
DIAGNOSIS FUNCTION
The SRS self-diagnosis results can be read by using “AIR BAG” warning lamp and/or CONSULT-II.
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-II 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.

FRONT WIPER AND WASHER SYSTEM

How to Perform Trouble DiagnosesBKS001TN
1. Confirm the symptoms and customer complaint.
2. Understand operation description and function description. Refer to WW-4, "
System Description" .
3. Perform the Preliminary Check. Refer to WW-18, "
Preliminary Check" .
4. Check symptom and repair or replace the cause of malfunction.
5. Does the front wiper and washer operate normally? If YES, GO TO 6. If NO, GO TO 4.
6. INSPECTION END
Preliminary CheckBKS001TO
CHECK POWER SUPPLY AND GROUND CIRCUIT
1. CHECK FUSES AND FUSIBLE LINK
Check for blown fuses and fusible link.
Refer to WW-11, "Wiring Diagram — WIPER —" .
OK or NG
OK >> GO TO 2
NG >> If fuse or fusible link is blown, be sure to eliminate cause of malfunction before installing new fuse
or fusible link. Refer to PG-3, "
POWER SUPPLY ROUTING CIRCUIT" .
2. CHECK POWER SUPPLY CIRCUIT
1. Turn ignition switch OFF.
2. Disconnect BCM connectors.
3. Check voltage between BCM harness connector and ground.
