(e) Check that continuity exists between the terminals with
the switch ON (float down).
(f) Pour the fluid back in the reservoir tank.
If operation is not as specified, replace the switch.
16. INSPECT PARKING BRAKE SWITCH
(a) Check that continuity exists between the terminal and
switch body with the switch ON (switch pin released).
(b) Check that no continuity exists between the terminal and
switch body with the switch OFF (switch pin pushed in).
If operation is not as specified, replace the switch or inspect
ground point.
17. INSPECT WASHER FLUID LEVEL WARNING LIGHT
(a) Disconnect the connectors from the level warning switch
and parking brake switch.
(b) Connect terminals on the wire harness side connector of
the level warning switch connector.
(c) Remove the GAUGE fuse and turn the ignition switch ON,
and check that the warning light comes on.
If the warning light does not light up, test the bulb.
