Wiper Switch: Testing and Inspection

WIPER AND WASHER: WIPER SWITCH: INSPECTION

INSPECTION

1. INSPECT WIPER SWITCH
(a) Check the continuity of wiper switch.




(1) Measure the resistance according to the value(s) in the table below.
Standard resistance:

Front Wiper Switch (W/O Rain Sensor)





Front Wiper Switch (W/ Rain Sensor)





Rear Wiper Switch





Front Washer Switch





Rear Washer Switch





(b) Intermittent Operation Check (W/O Rain Sensor)
(1) Connect the voltmeter (+) terminal to terminal C11-3 (+1) of the connector and the voltmeter (-) terminal to terminal C12-2 (EW).
(2) Connect the positive battery (+) lead to terminal C11-2 (+B) of the connector and the negative battery (-) lead to terminals C12-2 (EW) and C11-1 (+S).
(3) Turn the wiper switch to the INT position.
(4) Connect the positive battery (+) lead to terminal C11-1 (+S) of the connector for 5 seconds.
(5) Connect the negative battery (-) lead to terminal C11-1 (+S) of the connector. Operate the intermittent wiper relay and measure the voltage between terminals C11-3 (+1) and C12-2 (EW).





(c) Front Washer Operation Check (W/O Rain Sensor)
(1) Turn the washer switch to the OFF position.
(2) Connect the positive battery (+) lead to terminal C11-2 (+B) of the connector, and the negative battery (-) to the terminals C11-1 (+S) and C12-2 (EW).




(3) Connect the voltmeter (+) terminal to terminal C11-3 (+1) of the connector and the voltmeter (-) terminal to terminal C12-2 (EW). Turn the washer switch to the ON and OFF position, and measure the voltage between terminals C11-3 (+1) and C12-2 (EW).
(d) Rain Sensor Adjust Switch Operation Check (W/ Rain Sensor)




(1) Measure the resistance according to the value(s) in the table below.
Standard resistance:
