      WASH

      (Rear wiper switch ON position side)

      		 Below 1 Ω

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

    2. Check the intermittent operation.


      1. Connect the voltmeter's positive (+) lead to terminal B-3 (+1) and the negative (-) lead to terminal A-2 (EW).

      2. Connect the battery's positive (+) lead to terminal B-2 (+B) and the negative (-) lead to terminals A-2 (EW) and B-1 (+S).

      3. Turn the wiper switch to the INT position.

      4. Connect the battery's positive (+) lead to terminal B-1 (+S) for 5 seconds.

      5. Connect the battery's negative (-) lead to terminal B-1 (+S). Operate the intermittent wiper relay and check the voltage between terminals B-3 (+1) and A-2 (EW).

        OK
        Refer to illustration below.

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

    3. Check the washer operation.


      1. Turn the wiper switch OFF.

      2. Connect the battery's positive (+) lead to terminal B-2 (+B) and the negative (-) lead to terminals B-1 (+S) and A-2 (EW).

      3. Connect the voltmeter's positive (+) lead to terminal B-3 (+1) and the negative (-) lead to terminal A-2 (EW).

      4. Turn the washer switch ON and OFF, and check the voltage between terminals B-3 (+1) and A-2 (EW).

        OK
        Refer to illustration below.
