2) Speedometer
The speedometer indicates the vehicle speed by calculating the signals from the rear right
wheel speed sensor through ABS or ESP unit.
If the speedometer pointer vibrates, stands at a certain range or sounds abnormal noise, there
could be defectives in speedometer. However, these symptoms also could be appeared when
the tire has uneven wear, different tire inflation pressures or different tire specifications.
Perform the speedometer test regarding the tolerance as described. However, it is not simila
r
simple work in field due to lack of measuring conditions such as test equipment and
preciseness.
Check the allowable tolerance of the speedometer and operations of the trip odometer by
using a tester.
Check if the speedometer pointer is shaking and the abnormal noise sounds.
Eliminate the hysteresis by tapping the speedometer. 1.

The allowable tolerance increases when the tires are worn or the tire pressure is out of

3. EXTERIOR LAMP OPERATION
1) AIMING AND ADJUSTMENT OF FRONT LAMP
(1) Headlamp Aiming
An approved beam setting device should be used
for a correct headlamp aiming.
Make sure to follow the operating instructions
provided by the manufacturer.
If not available to use the beam setting device,
adjust the headlamp aiming with a screen. Headlamp aiming requirements:
- parking on a flat surface
- specified tire pressure
- one passenger (driver, 65 kg),
- spare tire and OVM tools loaded
(unlade all other loads)
Adjustment of low beam

ABS SYSTEM
2. GENERAL INFORMATION
The aim of the ABS is to mmaintain steerability and driving stability and to take the burden off
the driver. If the stopping distance is shorter on some road surfaces (carriageway conditions),
this is a gift of physics and not a development aim.
ABS is a device which senses that one or more of the wheels are locking up during braking. It
monitors the rotational speeds of the wheels and reduces hydraulic pressure to any wheel it
senses locking up. It is controlled by both mechanical and electronic components. When you
apply the brakes, the ABS will regulate the flow of brake fluid being delivered to the brake
calipers. By the use of electronic computers, the brakes rapidly alternate (at a rate of 30 times
per second) from full pressure to full release.
1) DRIVING PHYSICS
To give you a better understanding of the tasks and functions of ABS, we will first look at the
physics principles.
(1) The Stopping Distance
The stopping distance depends on the vehicle weight and initial speed when braking starts.
This also applies for vehicle with ABS, where ABS always tries to set an optimum brake force
on each wheel. As great forces are exerted between the tires and the carriageway when
braking, even with ABS the wheels may scream and rubber is left on the road. With an
ABS
skid mark one may be able to clearly recognize the tire profile. The skid mark of an ABS vehicle
does not however leave any hint of the speed of the vehicle in the case of an accident, as it can
only be clearly drawn at the start of braking.
(2) Brake Force on a Wheel
The maximum possible brake force on a wheel depends on the wheel load and the adhesion
coefficient between tire and carriageway. With a low adhesion coefficient the brake force, which
can be obtained is very low. You are bound to know the result already from driving on winte
r
roads. With a high adhesion coefficient on a dry road, the brake force, which can be obtained,
is considerably higher. The brake force, which can be obtained, can be calculated from below

2. TIRE’S ABNORMAL PHENOMENA
1) Standing Wave
2) Hydroplaning
During running the rotating tire repeats
deformation and restoring movement
generated in tread. But when the wheel
rotating speed reaches high, the next
deformation applied to tire before restoring
last deformation so the trembling wave
appears in the tread portion. The lower the
tire pressure the severe the trembling wave
appears during the high speed.
The condition of driving a vehicle fast on the
road surface covered with water can cause
tires to fail to rotate with a good contact on
the surface, so results in remaining them a
float. This is so-called hydroplaning. It
causes brake failure, lower tractive force
and losing the steering performance so it is
very vulnerable condition.
