bag sensor assembly.
OK:
Voltage: 10 − 14 V
NG Check SRS warning light bulb/repair SRS warn-
ing light circuit.
OK
4 Does SRS warning light come on?
PREPARATION:
(a) Disconnect negative ( −) terminal cable from the battery.
(b) Connect airbag sensor assembly connector.
(c) Connect negative ( −) terminal cable to battery, and wait
at least 2 seconds.
(d) Turn ignition switch to ACC or ON.
CHECK:

Periodic maintenance service must be performed according to whichever interval in\
the periodic main-
tenance schedule occurs first, the odometer reading (miles) or the time inter\
val (months).
Maintenance service after the last period should be performed at the same interval \
as before unless
otherwise noted.
Failure to do even one item can cause the engine to run poorly and incre\
ase exhaust emissions.
2. LIGHTS

and other lights are all working.
(b) Check the headlights aim.

(b) Check that the wipers do not streak.
7. WINDSHIELD DEFROSTER
Check that air comes out from the defroster outlet when operating the heater \
or air conditioner at defroster
mode.
8. REAR VIEW MIRROR
Check that it is mounted securely.
9. SUN VISORS
Check that they move freely and mounted securely.
10. STEELING WHEEL
Check that it has the specified freeplay. Be alert for changes in steering condition, such as hard steering,
excessive freeplay or strange noises.
11. SEATS
(a) Check that all front seat controls such as seat adjusters, seatback recl\
iner, etc. operate smoothly.
(b) Check that all latches lock securely in any position.
(c) Check that the head restraints move up and down smoothly and that the lo\
cks hold securely in any latch position.
