TRANSPONDER IMMOBILISER

Additional information

Before carrying out any work on the transponder immobiliser, have the machine master key and black key to
hand.
If the engine will not start, a first diagnostic may be carried out using the LED before checking the other parts
of the ignition system.
Note: Do not remove the diagnostic plug loop
In case of a fault, do not use an immobiliser module or ECU from another machine to carry out tests. The
keys, immobiliser module and ECU programmed on another machine form an assembly, are linked by a code
and must under no circumstances be separated.
Important: If an ECU is changed without memorising the keys, do not turn on the ignition more than 16
times if the diagnostic loop is disconnected as beyond this number, the ECU immobiliser function is erased.
