Immobilizer and Warning Lamp ▶
This indicator comes on when the ignition key
is communicating with the engine control unit
(during engine starting) and goes out after
starting the engine.
When turning the ignition key to the "ON"
position, the ECU (engine control unit)
transmits the challenge message to the
immobilizer & rechargeable unit.
(This is to verify whether the key is valid. If the
verification fails, it transmits re-verification
signals 3 times for 2 seconds. If three re-
verifications fail, it stops verification and starts
re-verification after 10 seconds.) (1)
ECUOnly when the two signals are identical, it recognizes the
key as the authorized one and transmits the positive
message to the ECU. (6)
The ECU enable the engine to be started. (7)
Do not drop or shock to the transponder in the key as it may be damaged.
With a damaged transponder, the engine cannot be started.
When you erase the code or register an extra key, please attend on the site.
In any cases, the immobilizer system can not be removed from the vehicle. If you attempt to
remove it and damage the system, starting will be impossible, so never attempt to remove,
damage or modify it.
The remote engine starter cannot be installed to the vehicle equipped with the immobilizer
system. ·

2. CONFIGURATION
1) RPM Gauge
The tachometer indicates engine speed in revolutions per minute. Multiply 1,000 to the current
number, then it will be the current number of engine revolutions.
Under the normal engine operating temperature, the proper idling speed is 700 ~ 800 rpm. The
red zone (danger rpm range) starts from 4,500 rpm.
Connect the tachometer for tune-up test and start the engine.
Eliminate the hysteresis by tapping the tachometer.
Compare the values on the tester and tachometer and replace the tachometer if the tolerance
is excessive. 1.
2.
3.
If the tachometer (engine rpm gauge) pointer vibrates or stops moving at a certain range, or
abnormal noises are heard from the tachometer, the tachometer may have a malfunction. If
you have reason to suspect that the reading from the tachometer differs from the actual engine
speed (rpm), connect a diagnostic device and compare the value on tachometer with the
reading from the diagnostic device.

2) Function of N Switch
(1) Aids a smooth start of the vehicle by raising the RPM during the gear
shifting when the engine is cold.
When the vehicle is trying to start from the stopped state (vehicle speed below 3 km/h), the N
switch determines the shifting timing by using the clutch switch and the N switch. It raises the
engine RPM (100 ~ 200 rpm). Operation conditions are as follows.
The vehicle speed is at the stopped state (Vehicle speed below 3km/h detection).
While depressing the clutch (Clutch switch detection).
The gear lever is at a position other than neutral (N switch detection).
Start the vehicle while depressing the clutch pedal (Clutch switch detection).
The RPM increases in accordance with the temperature of the engine coolant
(Engine coolant temperature sensor detection). -

When the gear has been smoothly shifted and the vehicle speed exceeds 3km/h, it returns to
the previous operation interval of the engine RPM. -
In case of Actyon, the N switch signal is transmitted to the instrument panel, and then the
instrument panel transmits it to the engine ECU through the CAN communication.

CBS: Conventional Brake System
ABS: Anti-Lock Brake System
EBD: Electronic brake-Force Distribution

Brake pad: Brake pad is a component of disk brakes used in automotive and other
applications. Brake pad is steel backing plates with friction material bound to the surface that
faces the brake disc.
Brake disc: The brake disc is a device for slowing or stopping the rotation of a wheel while it is
in motion.
Brake caliper: To stop the wheel, friction material in the form of brake pads (mounted on a
device called a brake caliper) is forced hydraulically against both sides of the disc. Friction
causes the disc and attached wheel to slow or stop.
Brake master cylinder: The brake master cylinder is a control device that converts non-
hydraulic pressure (commonly from a driver's foot) into hydraulic pressure, in order to move
other device(s) which are located at the other end of the hydraulic system, such as one or
more slave cylinders. As piston(s) move along the bore of the master cylinder, this movement
is transferred through the hydraulic fluid, to result in a movement of the slave cylinder(s). The
hydraulic pressure created by moving a piston (inside the bore of the master cylinder) toward
the slave cylinder(s) compresses the fluid evenly, but by varying the comparative surface-area
of the master cylinder and/or each slave cylinder, one will vary the amount of force and
displacement applied to each slave cylinder (relative to the amount of force and displacement
that was applied to the master cylinder). -

Let the engine run for 1 to 2 minutes and
stop it. If the brake pedal stroke is
shortened as pumping the brake pedal,
the system is normal. If not, the system is
defective.
Depress the brake pedal several times
with engine off. If the brake goes down
when starting engine with pedal
depressed, the system is normal. If not,
the system is defective.
Depress the brake pedal when the engine
is running. If the pedal height is not
changed for 30 seconds after stopping
the engine, the system is normal. If not,
the system is defective. 1.

2) Basic Theory of ABS Function
To give you a better understanding of the tasks and functions of ABS, we will first look at the
physics principles.
(1) Stopping distance
(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 winter
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
formula:
Maximum brake force ▶
FBmax = wheel load FR x coefficient of
frictionMh
The braking process cannot be described
sufficiently accurately with the brake forces
calculated. The values calculated only apply if
the wheel is not locked. In the case of a
locking wheel, the static friction turns into
lower sliding friction, with the result that the
stopping distance is increased. This loss of
friction is termed "slip" in specialist literature.
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.
