Driveaway Protection System (DWA): Components: Notes

The new DWA system of the E65 consists of the following components:

• Interior protection sensor with integrated DWA logic (DWA control unit).
• Emergency siren with integrated tilt sensor (SINE).
• DWA LED under the rear view mirror.
• Integration with vehicle electronics (e.g. hood or door contacts).

The interior sensor with integrated DWA logic and the emergency siren with integrated tilt sensor are new developments combining the functions of the previous systems.

Both components now have diagnostic capability. The interior sensor is connected directly to the K-CAN system. The tilt sensor (with emergency siren) is connected to the interior sensor via a sub-bus line (local data bus).
