nectors still connected.
(c) Turn the ignition switch ON and check that the warning
light lights up.
If the warning light does not light up, inspect the bulb or wire har-
ness.
21. w/o Power seat:
INSPECT BUCKLE SWITCH CONTINUITY
(a) Check that continuity exists between the terminals on the
switch side connector with the switch ON (belt fastened).
(b) Check that no continuity exists between the terminals on
the switch side connector with the switch OFF (belt unfas-
tened).
If operation is not as specified, replace the seat belt inner belt.
22. w/ Power seat:
INSPECT BUCKLE SWITCH CONTINUITY
(a) Check that continuity exists between terminals 1 and 2 on
the switch side connector with the switch ON (belt fas-
tened).
(b) Check that no continuity exists between terminals 1 and
2 on the switch side connector with the switch OFF (belt

WARNING SYSTEM OPERATION
(a) Connect the positive (+) lead from the battery to terminals
1 and 7.
(b) Connect the terminal 7 to terminal 9 through the 3.4±W
test bulb.
(c) Connect the negative (±) lead from the battery to terminal
10.
(d) Check that the bulb lights and the buzzer sounds for 4 ±
8 seconds.
(e) Return to step (a) and operate the chime again.
(f) Connect the negative (±) lead from the battery to terminal
8.
(g) Check that the buzzer stops sounding.
