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.
