6. AUTO WIPER SYSTEM OPERATION CHECK
(a) Spray once at the area where the rain sensor is placed, then the wiper blades immediately will carry
out a wiping cycle. If the water is continuos sprayed to the rain sensor area of the windscreen, the wiper
blades first should carry out interval mode, then change to low speed and finally reach high speed after
a few seconds.
By stopping spraying water to the screen the wiper blade changing back their speed until they stop
wiping.
