        INT 2 (E) - 13 (C1R) Below 1 Ω
        ON 2 (E) - 10 (+1R) Below 1 Ω
        ON + WASH

        2 (E) - 12 (WR)

        2 (E) - 10 (+1R)

        		 Below 1 Ω

        If the result is not as specified, replace the wiper switch.

    2. Intermittent Operation Check


      1. Connect the voltmeter (+) terminal to terminal 7 (+1) and the voltmeter (-) terminal to terminal 2 (E).

      2. Connect the battery's positive (+) lead to terminal 17 (+B), and connect the battery's negative (-) lead to terminals 2 (E) and 16 (+S).

      3. Turn the wiper switch to the INT position.

      4. Connect the battery's positive (+) lead to terminal 16 (+S) for 5 seconds.

      5. Connect the battery's negative (-) lead to terminal 16 (+S) to operate the intermittent wiper relay. Measure the voltage between terminals 7 (+1) and 2 (E).

        OK
        Refer to the illustration below.

        If the result is not as specified, replace the wiper switch.

    3. A01BD74E01

      Front Washer Operation Check


      1. Turn the wiper switch to the OFF position.

      2. Connect the battery's positive (+) lead to terminal 17 (+B), connect the battery's negative (-) to terminals 16 (+S) and 2 (E).

      3. Connect the voltmeter (+) terminal to terminal 7 (+1) and the voltmeter (-) terminal to terminal 2 (E). Measure the voltage between terminals 7 (+1) and 2 (E) when turning the washer switch ON and OFF respectively.

        OK
        Refer to the illustration.

        If the result is not as specified, replace the wiper switch.

  2. INSPECT WIPER SWITCH (RHD)
