SERVICE ADJUSTMENT PROCEDURES
FRONT WHEEL ALIGNMENTM33FBAQ
NOTE
The front suspension assembly must be free of worn, loose or
damaged parts prior to measurement of front wheel align- ments. Measure wheel alignment by using the tool.
CAMBER AND CASTER
Standard value:

Camber22’ f 30’ 31’& 30
Caster2”f301”56’rtr30
Camber and caster are pre-set at the factory and cannot be
adjusted.
NOTE
If camber and caster are not within specifications, replace bent
or damaged parts.
TOE-IN
Standard value: Ok3 mm (Of .12 in.)
1. Adjust the toe-in by undoing the clips and turning the left and right tie rod turnbuckles
by the same amount (in
opposite directions).
2. The toe will move out as the left turnbuckle
is turned
toward the front of the vehicle and the right turnbuckle is
turned toward the rear of the vehicle.
3.For each half turn of the left and right tie rods, the toe-in will
be adjusted by 6 mm
(24 in.).
4.After making the adjustments, use a turning radius gauge to confirm that the steering wheel turning angle is within the
standard value range. (Refer to GROUP
37A-Service
Adjustment Procedures.)

ALARM LIGHT CHECK
MPFNAC
The bulb of the alarm light can be checked by whether or not it is illuminated for approximately 0.5 of a second by the
Electronic Control Suspension control unit when the ignition
key is turned ON, and, after the engine is started.
SYSTEM CHECKING BY USING ALARM LIGHT 1. After checking the alarm light bulb to be sure it has not failed, let the engine idle for approximately 4 minutes ormore to check to be sure that the alarm light does not
illuminate.
2.While the alarm light is on, connect the scan tool or a volt- meter to the data link connector of the wiring harness and
check the on-board diagnostic output code.
3. Use the output pattern for troubleshooting (Refer to
P.33B-11.)
NOTE*
Although the alarm light illuminates under the following
circumstances, there is no actual malfunction if, after the
following procedures have been followed and then the
alarm light does not illuminate after waiting about four
minutes or more.
1. When there is an overload Stop the engine, unload the cargo, and then restart the
engine.
2.When the vehicle is stopped (with the engine running)
on a steep hill or slope.Move the vehicle to a horizontal place and stop; then
stop the engine and restart it.
