TROUBLESHOOTING

M1511000700323

The windshield wiper and washer are controlled by 
the Smart Wiring System (SWS). For troubleshoot-
ing, refer to GROUP 54B, Troubleshooting 

P.54B-15

 

or GROUP 54C, Troubleshooting 

P.54C-4

.

NOTE: Even when the ETACS-ECU has failed, the 
windshield wiper can work at low speed as fail-safe 
mode. (Normally, the windshield wiper operates 
when the ignition switch is at the "ACC" position. But, 
if it enters the fail-safe mode, the wiper can operate 
only when the ignition switch is at the "ON" position.)

WINDSHIELD INTERMITTENT WIPER 
INSPECTION

1. If the windshield intermittent wiper interval 

adjusting knob is operated, the wiper interval 
should change.

2. Holding the windshield intermittent wiper interval 

adjusting knob, input the simulated vehicle speed 
with M.U.T.-II / III and check that the wiper interval 
changes as the vehicle speed changes.

3. If not, carry out the troubleshooting (Refer to 

GROUP 54B, Troubleshooting 

P.54B-15

 or 

GROUP 54C, Troubleshooting 

P.54C-4

).
