Wiper Switch: Testing and Inspection
INSPECTION1. INSPECT WIPER SWITCH
a. Check the continuity of wiper switch.
1. Measure the resistance according to the value(s) in the table.
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 C11-4 (+S) of the connector. Operate the intermittent wiper relay and measure the voltage between terminals C11-3 (+1) and C12-2 (EW).
c. Front Wiper Operation Check (w/o Rain Sensor)
1. Turn the wiper 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.
