        Connect a voltmeter positive (+) lead to terminal H25-3 (+1) and a negative (-) lead to terminal H24-4 (EW).

      2. Turn the engine switch on (IG).

      3. Turn the wiper switch to the INT position.

      4. Operate the intermittent wiper and check the voltage between terminals H25-3 (+1) and H24-4 (EW).

        OK
        Voltage changes as shown in the illustration.
