Brake Warning
INSPECTION OF BRAKE WARNING
1. INSPECT WARNING LIGHT OPERATION
(a) Disconnect the connectors from the level warning
switch and parking brake switch.
(b) Connect terminals on the wire harness side of the
level warning switch connector.
(e) Remove the CHARGE fuse and turn the ignition
switch
ON, check that the warning light lights.
If the warning light does not light, test the bulb.
2. INSPECT LEVEL WARNING SWITCH OPERATION
(a) Check that there is no continuity between terminals
with the switch OFF (float up).
(b) Check that there is continuity between terminals with
the switch ON (float down).
If operation is not as specified, replace the switch.
Open Door Warning
INSPECTION OF OPEN DOOR WARNING
1. INSPECT WARNING LIGHT OPERATION
(a) Disconnect the connector from the door courtesy switch
and ground it.
(b) Turn the ignition switch ON, check that the warning light
lights.
If the warning light does not light, test the bulb.
2. INSPECT COURTESY SWITCH OPERATION
(a) Check that there is continuity between terminal and
switch body with the switch pin released.
(b) Check that there is no continuity between terminal and
switch body when the switch pin is pushed in.
If operation is not as specified, replace the switch. 3. INSPECT PARKING BRAKE SWITCH OPERATION
(a) Check that there is continuity between terminal and
switch set nut with the switch pin released.
(Parking brake lever pulled up)
(b) Check that there is no continuity between terminal
and switch set nut with the switch pin pushed in.
(Parking brake lever released)
If operation is not as specified, replace the switch.
