Circuit inspection of the control switch
(Fig.S-307)
Remove the connector I B-55l of the control
switch and check the voltage and continuity of
the harness side connector of the vehicle. •
When
there is no continuity at the terminal No.
5, 7, 8, 10, it is considered that the circuit with
terminal N0.1 (8/W) is defective.
