1) Disconnect negative cable (–) at battery.
2) Disconnect combination switch lead wire coupler.
3) Turn the front wiper switch to INT position.
4) Connect battery positive terminal (+) to terminal “B3” and bat-
tery negative terminal (–) to terminal “HE”.
5) Connect voltmeter positive lead to terminal “+1” and negative
lead to terminal “HE”. Check that the voltmeter indicates the bat-
tery voltage (10 – 14V).
6) Connect terminal “As” and terminal “B3” by a jumper wire. Then
connect terminal “B3” end to terminal “HE”.
Observe the voltmeter voltage drops to 0V right after connect-
ing the jumper wire from terminal “B3” to “HE”. Then the voltage
rises to battery voltage (10 – 14 V) within the time shown below.
