Immobiliser function
This vehicle is fitted with an engine immobiliser controlled by a random rolling code key recognition system.
REPLACING AN INJECTION COMPUTER
The injection computers are supplied without a code but they must all be programmed with one.
When the computer is replaced, the vehicle code must be programmed in and then a check must be made to ensure
that the immobiliser system is operational.
To do this, simply switch on the ignition for a few seconds without starting the engine then switch it of f. When the
ignition is off, the engine immobiliser function will be activated after approximately 10 seconds (red engine
immobiliser warning light flashes).
IMPORTANT:
With this engine immobiliser, the computer keeps its immobiliser code for life.
In addition, this system does not have a security code.
Consequently, it is forbidden to perform tests with computers borrowed from the stores or from another
vehicle which must then be returned.
It will no longer be possible to decode them.
