Remote System Coding

Remote System Coding
As with previous keyless entry Systems, the E38 remote system uses coded signals for security purposes. The code signal sent by the transmitter is changed every time the vehicle is locked/unlocked with the transmitter. A separate code word group is used for each transmitter that is initialized to the system. This allows for each transmitter to operate independently of the others.

Due to the changing of the code each time the buttons are pressed, the system allows for a lack of synchronization between the transmitter and receiver. This would occur if the buttons on the transmitter are pressed inadvertently.

Up to 100 erroneous actuations of the transmitter are automatically corrected for by the control module. If more than 100 actuations are present, the operator need only to press the button a second time to restore the system operation.

If more than 1000 erroneous actuations exist, the complete transmitter group must be reinitialized.
