  1. Intermittent Operation Check ( w/o Rain Sensor)

    1. Connect the voltmeter (+) terminal to terminal C10-3 (+1) of the connector and the voltmeter (-) terminal to C11-2 (EW).

    2. Connect the position battery (+) lead to terminal C10-2 (+B) of the connector and the negative battery (-) lead to terminals C11-2 (EW) and C10-1 (+S).

    3. Turn the wiper switch to the INT position.

    4. Connect the position battery (+) lead to the terminal C10-1 (+S) of the connector for 5 seconds.



    5. Connect the negative battery (-) lead to terminal C10-4 (+S) of the connector. Operate the intermittent wiper relay and measure the voltage between terminal C10-3 (+1) and terminal C11-2 (EW).
