(b) Turn the ignition switch ON, and check that the warning light lights up.
If the warning light does not light up, test the bulb.
20. INSPECT DOOR COURTESY SWITCH
(a) Check that there is continuity between terminal and the
switch body with the switch ON (switch pin re-
leased:opened door).
(b) Check that there is no continuity between terminal and
the switch body with the switch OFF (switch pin pushed
in:closed door).
If operation is not as specified, replace the switch.
21. INSPECT SEAT BELT WARNING LIGHT
(a) Disconnect the connector from the seat belt warning relay.
(b) Ground terminal 9 on the wire harness side connector.
(c) Turn the ignition switch ON, and check that the warning
light lights up.
If the warning light does not light up, test the bulb.
22. INSPECT SEAT BELT BUCKLE SWITCH CONTINUITY
(a) Check that there is continuity between terminals with the switch ON (belt unfastened).

BRAKE FLUID
BLEEDING
HINT:
If any work is done on the brake system or if air is suspected in
the brake lines, bleed the system of air.
NOTICE:
Do not let brake fluid remain on a painted surface. Wash it
off immediately.
1. FILL BRAKE RESERVOIR WITH BRAKE FLUID
Check the fluid level in the reservoir after bleeding each wheel.
Add fluid, if necessary. Fluid: SAE J1703 or FMVSS No.116 DOT3
2. BLEED MASTER CYLINDER
HINT:
If the master cylinder has been disassembled or if the reservoir
becomes empty, bleed the air from the master cylinder.
(a) Disconnect the brake lines from the master cylinder.
(b) Slowly depress the brake pedal and hold it.
(c) Block off the outlet plugs with your fingers, and release the brake pedal.
(d) Repeat (b) and (c) 3 or 4 times.
3. CONNECT VINYL TUBE TO BRA KE CALIPER BLEED-
ER PLUG
Insert other end of the tube in a half −full container of brake fluid.
