7. INSPECT SEAT BELT WARNING LIGHT & BUZZER
(a) Check the operation.
(1) Turn the ignition switch to ON and check that the warning light comes on.\
(2) Fasten the outer belt to the inner belt and check that the warning light\
goes out.
(3) Disconnect the connector from the buckle switch and ground the terminal \
on the wire harness
side connector.
(4) Turn the ignition switch to ON and check that the warning light comes on.\
8. INSPECT LOW OIL PRESSURE WARNING LIGHT
(a) Inspect the circuit. (1) Disconnect the connector from the low oil pressure switch.
(2) Turn the ignition switch to ON.
(3) Ground the terminal of the wire harness side connector, then check the low oil pressure warninglight.
Low oil pressure warning light: Come on
9. INSPECT BRAKE WARNING LIGHT
(a) Inspect the parking brake warning light.
(1) Disconnect the connector from the parking brake switch and ground the terminal on the wire har-ness side connector.
(2) Turn the ignition switch to ON and check that the warning light comes on.\
(b) Inspect the brake fluid level warning light.
(1) Disconnect the connector from the brake fluid level warning switch and c\
onnect the terminalson the wire harness side connector.
(2) Turn the ignition switch to ON and check that the warning light comes on.\
10. INSPECT BRAKE FLUID LEVEL WARNING SWITCH
(a) Inspect the continuity.
(1) Remove the reservoir tank cap and strainer.
(2) Disconnect the connector.

B HOW TO USE THIS MANUAL
Current is applied at all times through the STOP fuse to TERMINAL 2 of the stop light SW.
When the ignition SW is turned on, current flows from the GAUGE fuse to TERM\
INAL 8 of the light failure sensor, and also flows
through the rear lights warning light to TERMINAL 4 of the light failure sensor\
.
Stop Light Disconnection Warning
When the ignition SW is turned on and the brake pedal is pressed (Stop ligh\
t SW on), if the stop light circuit is open, the cur
rent
flowing from TERMINAL 7 of the light failure sensor to TERMINALS 1, 2 changes, \
so the light failure sensor detects the
disconnection and the warning circuit of the light failure sensor is activated.
As a result, the current flows from TERMINAL 4 of the light failure sens\
or to TERMINAL 11 to GROUND and turns the rear lights
warning light on. By pressing the brake pedal, the current flowing to TERMINAL \
8 of the light failure sensor keeps the warning
circuit on and holds the warning light on until the ignition SW is turne\
d off.

B HOW TO USE THIS MANUAL
The ground points circuit diagram shows the connections from all major p\
arts to the respective ground points. When
troubleshooting a faulty ground point, checking the system circuits which use a common \
ground may help you identify
the problem ground quickly. The relationship between ground points (
EA, IB and IC shown below) can also be
checked this way.
