Body Control Systems: Description and Operation
61 11 03 (018) Body electrical/electronic system E60/E61/E63/E64
Introduction
This document lists the functions of the body electrical/electronics system.
Overview of functions
The electrical/electronics system comprises the following functions:
Car Access System (SI Technology 610303019) Car Access System
The Car Access System (CAS) controls access to the vehicle.
The CAS control unit is the master control unit for the central locking system, power windows and sliding/tilt sunroof (remote control and convenience features).
Central locking system (SI Technology 610403020) Central Locking System
The front door central locking system is controlled by the driver's door modules (TMFA) or front passenger door modules (TMBF).
The central locking system for the rear doors, fuel filler flap and the boot-lid unlocking are controlled by the body basic module (KBM).
In the E61 the rear window is also monitored by the central locking system.
The automatic luggage compartment lid actuation (tailgate lift) has an automatic soft-close mechanism.
In the E63/E64 the storage compartment in the center console is also monitored by the central locking system.
Power windows (SI Technology 610503025) Description and Operation
The power windows in the front doors are controlled by the driver's door module (TMFA) and the front-passenger door module (TMBF).
The window lifters for the rear doors are actuated by the body basic module (KBM).
In the E63 there are no power windows for the rear doors.
In the E64 the rear power windows do not have an anti-trap circuit.
Sliding/tilting sunroof (SI Technology 610803030) Sliding/Tilt Sunroof E60
The sliding/tilt sunroof is controlled by the control unit for the sliding/tilt sunroof (SHD control unit). The SHD control unit is attached directly to the motor for the sliding/tilt sunroof.
The E61 can be fitted with a panorama glass sunroof.
The E63 can be fitted with a glass tilt sunroof.
Wash/wipe system (SBT610603026) Wash/Wipe System E60/E61/E63/E64
The wash/wipe system is controlled by the body basic module KBM. The rain-light sensor is standard equipment.
The E61 has a wash/wipe system for the rear window.
Door mirrors (SI Technology 611003032) Exterior Mirrors
The door mirrors are controlled by the driver's door module (TMFA) and the front-passenger door module (TMBF). The door modules communicate via Byteflight.
DWA anti-theft alarm system
The anti-theft alarm system detects and reports attempts at intrusion and tampering with the vehicle.
The E60/E61 is monitored by an ultrasound interior movement detector (SI Technology 610903031) Anti-Theft Alarm System E60/E61.
The E63/E64 are monitored by microwaves (SI Technology 650403061).
There are no significant new features in the interior lighting and the roller sunblind:
- Interior lighting
The interior lighting is controlled automatically by several input signals.
The driver's door modules (TMFA) and front passenger's door modules (TMBF) control:
- frontlighting for the handle recess and the storage compartment in the front doors
- door entry lighting, front
- courtesy lighting (light conductor in the door mirror)
The body basic module (KBM) controls:
- interior lights including reading lamps
(model-specific)
- lighting for the make-up mirror
- glove-compartment light
- footwell lamps, front
- door entry lighting, rear
(E60/E61 only)
- lighting for the handle recess and the storage compartment in the rear doors
(E60/E61 only)
- boot light
(model-specific)
- Roller sunblind
There is an electrically powered roller sunblind for the rear window (E60 only).
The control is integrated in the switch block in the driver's door.
The output stage for controlling the roller sunblind is located in the center console switching center (SZM).
