Function
After inserting the transmitter key into the ignition/starter switch (S2/1) the ID code of the transmitter key is received inductively by the transponder coil when circuit 15 is ON. It directly relays the ID code to the SAM control unit for checking. If the ID code is valid, the SAM control unit relays this information via CAN to the ME-SFI control unit which enables the engine control. Moreover, the transmitter key is supplied inductively with power via the transponder coil, so that the vehicle can also be started when the battery in the vehicle transmitter key is discharged.
Up to 6 transmitter keys can be used. The key data is managed by the SAM control unit.
Status messages from the drive authorization systems are transmitted to the instrument cluster by the SAM control unit. The instrument cluster sends the status message via the multifunction display.
