IMMOBILIZER

IMMOBILIZER
The vehicle is equipped with an immobilizer that stops the
engine from being started if the correct code is not entered.
The code is stored in the transponder in each of the two keys
supplied with the vehicle. An antenna, mounted in the igni-
tion switch that is directly connected to the ECU, reads the
transponder data.
The immobilizer is completely independent of the CAN.
The immobilizer mode is indicated by a led on the
dashboard, as follows:
- immobilizer de-activated: led off
- immobilizer activated: led flashes every 3 seconds (war-
ning function)
- incorrect key: led flashes every second
The led stops flashing after 240 hours to save energy.
STORING NEW KEY CODES (VIRGIN MEMORY)
When the immobilizer ECU is first powered up, its memory is
virgin and the led stays on without flashing. To store the first
two key codes :
- run a key ON cycle with the first key: the led will switch
off for 0.5 sec and turn on again. When it turns on, turn
the key to OFF.
- turn the second key supplied to ON within 20 seconds.
The led will switch off and immediately flash 4 times.
Now turn the key to OFF. The two keys are now stored and
the immobilizer is activated (led flashes every 3 seconds as
a warning).
The two keys are now stored and the immobilizer is activated
whenever the key is turned to OFF (led flashes every 3 sec-
onds as a warning)
If power fails after the first key is stored, the system will reset
(first key data also cancelled). After the first key has been
stored, all vehicle and dashboard's functions are enabled.
The key is not stored definitively if the second key is not
stored within 20 seconds.
