2. CHECKING CABLES AND WIRES
Check for loose connection or rust.
Check terminals and wires for corrosion due to electrolyte leakage.
Check terminals and wires for open circuit.
Check the wire insulation and coat for damage, cracks or deterioration.
Check if the conductive parts of the terminals do not contact with vehicle body or other metal
parts.
Check that the grounding part has continuity with mounting bolts and vehicle body.
Check that wires are properly routed.
Make sure that wires are securely fixed to avoid contact with sharp body parts and hightemperature
parts, such as the exhaust manifold and exhaust pipes.
The rotating parts, such as fan pulley and fan belt, perturbative parts and wiring should be
secured tightly at regular intervals.
Secure the wiring between the fixed parts, such as the vehicle body, and vibrating parts, such
as the engine, after slackening it slightly to prevent it from being damaged. -

2. CAUTIONS
The vehicle owner must observe the service works when deleting the transponder codes or
registering additional keys.
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.
Do not drop or shock to the transponder in the ignition key as it may be damaged.
With a damaged transponder, the engine cannot be started.
For the vehicle with the immobilizer, there can be a problem in starting the vehicle or the system

2. OVERVIEW
The Immobilizer System provides an additional theft deterrent to the vehicle in which it is installed and
prevents it from being started by unauthorized persons. The transponder integrated in the key and the
engine control unit have the same code. When the ignition key with the integrated transponder is
turned to the ON position, the ECU (Engine Control Unit) checks the crypto code of the key and, if
correct, allows the vehicle to start the engine. If the verification has been failed, the engine cannot be
started and the immobilizer warning lamp blinks.

3. VERIFICATION OF KEY
1) Verification
The immobilizer system prevents the vehicle theft by allowing only the authorized key to start the
engine. The transponder inside the key communicates with the immobilizer installed in the key box,
and the system permits the engine to start after confirming the encrypted coding from the engine ECU.
In the following cases, a driver may be unable to start the vehicle with the immobilizer.The immobilizer unit transmits
the encrypted code to the
transponder. (2)
The transponder sends an encrypted signal to the unit as a response.
The transmitted code is changed to an encrypted signal in the unit.
The system compares the signal from transponder and the encrypted signal in immobilizer unit. (3)
(4)
(5)
When two or more immobilizer keys come into contact with (each) other(s).
When the key is close to any device sending or receiving electromagnetic fields or waves.
When the key is close to any electronic or electric devices such as lightening equipment,
security keys or security cards.
When the key is close to a magnetic or metal object or a battery. -

ECU
Immobilizer Indicator 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 ON position, the
ECU transmits the challenge message to the
immobilizer unit to verify whether the key is valid. (1)
Only when the two signals are identical, it
recognizes the key as the authorized one and
transmits the positive message to the ECU.
The ECU allows the engine to be started. (6)
(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, let the owner attend on the site.
In any case, the immobilizer system cannot 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 on the vehicle equipped with the immobilizer
system. -
