AIRBAG SENSOR ASSEMBLY

Never reuse the airbag sensor assembly involved in a collision when the SRS has deployed.

The connectors to the airbag sensor assembly should be connected or disconnected with the sensor
mounted on the floor. If the connectors are connected or disconnected while the airbag sensor as-
sembly is not mounted to the floor, it could cause undesired ignition of the supplemental restraint sys-
tem.

Work must be started after 90 seconds from the time the ignition switch is turned to the ºLOCKº posi-
tion and the negative (-) terminal cable is disconnected from the battery, even if only loosening the
set bolts of the airbag sensor assembly.
WIRE HARNESS AND CONNECTOR

The SRS wire harness is integrated with the cowl wire harness assembly and floor wire harness as-
sembly. The wires for the SRS wire harness are encased in a yellow corrugated tube. All the connec-
tors for the system are also a standard yellow color. If the SRS wire harness becomes disconnected
or the connector becomes broken due to an accident, etc., repair or replace it as shown on page.
2. BRAKE SYSTEM
The brake system is one of the most important safety components. Always follow the directions and
notes given in section BR of the repair manual for the relevant model year when handling brake sys-
tem parts.
NOTICE: When repairing the brake master cylinder or TRAC system, bleed the air out of the TRAC
system.
3. DRIVE TRAIN AND CHASSIS
The drive train and chassis are components that can have great effects on the running performance
and vibration resistance of the vehicle. After installing components in the sections listed in the table
below, perform alignments to ensure correct mounting angles and dimensions. Particularly accurate
repair of the body must also be done to ensure correct alignment.
HINT: Correct procedures and special tools are required for alignment. Always follow the directions
given in the repair manual for the relevant model during alignment and section Dl of this manual.
4. COMPONENTS ADJACENT TO THE BODY PANELS
Various types of component parts are mounted directly on or adjacently to the body panels. Strictly ob-
serve the following precautions to prevent damaging these components and the body panels during
handling.

Before repairing the body panels, remove their components or apply protective covers over the com-
ponents.

Before prying components off using a screwdriver or a scraper, etc., attach protective tape to the tool
tip or blade to prevent damaging the components and the body paint.

Before removing components from the outer surface of the body, attach protective tape to the body
to ensure no damage to painted areas.
HINT: Apply touch-up paint to any damaged paint surfaces.

Before drilling or cutting sections, make sure that there are no wires, etc. on the reverse side.

INSPECTION
1. MEASURE VEHICLE HEIGHT
Vehicle height:
FrontA - B: 71 mm (2.795 in.)
RearC - D: 51 mm (2.008 in.)
Measuring points:
A: Ground clearance of spindle center
B: Ground clearance of lower suspension arm front bolt center
C: Ground clearance of rear axle shaft center
D: Ground clearance of lower control arm front bolt center
NOTICE:
Before inspecting the wheel alignment, adjust the vehicle
height to the specified value.
If the vehicle height is not the specified value, try to adjust it by
pushing down on or lifting the body.
2. INSTALL CAMBER-CASTER-KINGPIN GAUGE OR
POSITION VEHICLE ON WHEEL ALIGNMENT TES-
TER
Follow the specific instructions of the equipment manufacturer.
3. INSPECT CAMBER, CASTER AND STEERING AXIS
INCLINATION
Camber, caster and steering axis inclination:
Camber
Right-left error0°05' ± 45' (0.08° ± 0.75°)
30' (0.5°) or less
Caster
Right-left error2°30' ± 45' (2.5° ± 0.75°)
30' (0.5°) or less
Steering axis inclination
Right-left error12°10' ± 45' (12.17° ± 0.75°)
30' (0.5°) or less
If the steering axis inclination is not within the specified value,
after the camber and caster have been correctly adjusted, re-
check the steering knuckle and front wheel for bearing or loose-
ness.
