box, and the system permits the engine to start after confirming the encrypted coding from the
engine ECU.

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.
