REPLACING THE ECM
This vehicle is fitted with an engine immobilizer system which is controlled by a key recognition system.
The ECM is supplied without a code but they must all be programmed with one.
If an ECM is replaced, it must be programmed with the code of the vehicle and the correct operation of the
engine immobilizer function must be checked.
WARNING:
These vehicles have a special ECM which does not function unless it is coded.
Consequently, it is strongly recommended that you do not carry out tests using ECMs borrowed from
the warehouse or on another vehicle to prevent coding and uncoding malfunctions which may leave
the ECM useless.
UNCODING PROCEDURE
If the ECM has learnt a code and must be returned to the workshop, it is imperative that you uncode it before
removing it.
