E88 Complete Vehicle
General Vehicle Electrical System
Because the vehicle systems network in the E88 is the same as that in the E93, only new
features and differences will be described here. For detailed information on the vehicles
systems network , refer to ST701 training material.
Central Locking System
In contrast to the E93, in the E88 the glove compartment and the storage compartment
in the center console are not locked/unlocked automatically.
Anti-theft Alarm System
The anti-theft alarm system in the E88 is similar to that in the E93 in terms of its basic
functions and operation. There are some differences when it comes to interior monitoring.
Three microwave sensors are used on the E88 for the purpose of monitoring the interior.
The microwave sensors are connected via the DWA bus to the SINE (siren with tilt alarm
sensor). The DWA bus is a sub-bus based on the K-bus. SINE is the master control
module and is connected directly to the K-CAN.
The microwave sensors facilitate monitoring of the vehicle interior also when the convert-
ible top is down. The microwave sensors have a semicircular radiation range characteris-
tic. By strategic placement in the vehicle, the entire interior can be monitored.
