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
