CAUTION:
 Check combination switch system terminal waveform under the loaded condition with lighting
switch, turn signal switch and wiper switch OFF not to be fluctuated by overloaded.
 Turn wiper intermittent dial posi tion to 4 except when checking wavef orm or voltage of wiper inter-
mittent dial position. Wiper intermittent dial position can be confirmed on CONSULT-III. Refer to WW-
15, "CONSULT-III Functions (BCM)".

How to Proceed with Trouble DiagnosisINFOID:0000000001328550
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-14, "
Preliminary Check".
4. Check symptom and repair or r eplace the cause of malfunction.
5. Does the front wiper and washer operate norma lly? If YES, GO TO 6. If NO, GO TO 4.
6. INSPECTION END
Preliminary CheckINFOID:0000000001328551
CHECK POWER SUPPLY AND GROUND CIRCUIT
1.CHECK FUSE
Check for blown fuses.
Refer to WW-8, "
Wiring Diagram - WIPER -".
OK or NG
