BACKUP LIGHT SWITCH (M/T)
~ INSPECTION (FIG. 8-148}
[!) 1.
Fig. 8-148
With the switch
installed to the transmission,
check the continuity between the
terminals of
the switch connectors.
When the continuity is found between the
terminals only with the switch shifted to the
reverse position, the switch
is normal.
2. When the result of the above inspection is
found abnormal, remove the switch from
the transmission and conduct a test on the
switch
alone.
If
the continuity appears between the con­
nector
terminals when the ball of the switch is
released, the switch is normal. (When the ball
is pushed, the continuity disappears.)
3. If there is no continuity with the switch
installed to the transmission, even though
the switch is found to be normal, then adjust
the stroke
of the switch by changing the
thickness
of the switch gasket.

Preparation: Disconnect the battery ground cable.
1. Driver inflator module (Fig. 8-154)
• Disconnect the Supplemental Restraint Sys­
tem (SRS) -AIR BAG connector located at
lower of the instrument panel driver lower
cover.
• Remove four screws.
• Disconnect the inflator module connector.
CAUTION:
When carrying a live inflator module, make sure
the bag opening is pointed away from you. In
case of an accidental deployment, the bag will
then deploy with minimal chance of injury.
Never carry
the inflator module by the wires or
connector on the underside of the module.
When placing a live inflator module on a bench
or other surface, always face the bag and trim
cover up, away from the surface. This is
necessary so
that a free space is provided to
allow the air bag to expand in the unlikely event
of accedental deployment.
2. Horn switch (Fig. 8-155)
• Remove the screws.
• Disconnect the switch connector.
l·u·IINSTALLATION
To install, follow the removal steps in the reverse
order, noting the
following point.
1. When connect the double lock type of inflator
module connectors, insert the connector
completery and lock at outside. Imperfect locking
may cause malfunction of Supplemental
Restraint System (SRS)-AIR BAG circuit.

MEMO

8-128 CHASSIS ELECTRICAL
DOME LIGHT, LUGGAGE ROOM LIGHT, COURTESY LIGHT,
MAP LIGHT, SEAT BELT SWITCH AND WARNING BUZZER
GENERAL DESCRIPTION
This circuit consists of the starter switch, door switch, dome light, luggage room light, courtesy lig t, map
light, seat belt switch, key remind switch and warning buzzer.
The dome
light lights up when any one of doors except the tailgate is opened with the switch set at t e door
mode. (Vehicles with a built-in timer do not have door mode.) !
The courtesy lights for the front doors are controlled by a circuit different from the one which cont ols the
courtesy
lights for the rear doors. When a door is opened, the lights on both sides in either front or r ar seat
light up.
The
luggage room light illuminates by opening the tailgate when the switch is set at the door mode.
The
map light illuminates by turning the switch on.
All these lights light up by turning on respective switches regardless of the position of the starter swi ch key.
The
warning buzzer sounds to remind the driver of seat belt use, leaving the key in the starter sv.. tch, or
headlights were left on.
