1. |
The ECM(PCM) (A) carries out a check of the ignition key using
a special encryption algorithm, which is programmed into the transponder
as well as the ECM simultaneously. Only if the results are equal, the
engine can be started. The data of all transponders, which are valid
for the vehicle, are stored in the ECM.
ERN (Encrypted Randorn Number) value between EMS and encrypted
Immobilizer unit is checked and the validity of coded key is decided
by EMS.
