Body Electronics - Overview: Overview BMW 5 series E60/E61

Model: E60, E61, E63 and E64

Production: All

Emergency Operation

In Emergency Mode, the sunroof only moves for 750 ms at a time. The emergency function is only available when the CAS has signaled the SHD control module, "Emergency Mode Enable", via the K-CAN.

Emergency operation is active under the following conditions

1. Coding Invalid
2. Defective Hall-sensor
3. Initialization incomplete

If initialization is incomplete operation is permitted based on scaling or characteristic curves.

With no scaling, movement is allowed only in the direction of the scaling position.

With no characteristic curve learned, movement is only is the closing direction.

Toll Operation

All control functions are also available as toll functions (comfort functions). They are activated by pressing beyond the switch notch.

1. Open sunroof visor only
2. Open sunroof visor and roof panel (up to comfort setting)
3. Roof panel tilt position and visor vent position
4. Close roof panel only
5. Close roof panel and sunroof visor
6. Close sunroof visor only with roof panels already closed

Principle of Operation

The anti-theft alarm system incorporates the following functions

1. Priming/disarming
2. DWA alarm triggering (alarm-trigger signal)
3. Automatic adaptation of sensitivity of ultrasonic interior motion sensor
4. Deactivating interior motion sensor and tilt alarm sensor
5. Emergency function for acoustic DWA alarm
6. Combined operation with lock cylinder and remote control

Combined Operation With Lock Cylinder And Remote Control

The alarm system can be primed and disarmed by either the door lock or the remote control (= combined operation). In some countries, insurance requirements prohibit such combined operation.

In the event of the combined operation failing, the alarm system can still be primed at the door lock, but cannot be disarmed at the door lock. Disarming is only possible with the remote control. The function of the combined operation can be encoded in the CAS control unit.

The anti-theft alarm system incorporates the following functions

1. Activating and deactivating
2. DWA alarm triggering (alarm-trigger signal)
3. Undervoltage recognition, overvoltage recognition, car battery monitoring (positive and negative cables)
4. Monitoring of sub-bus
5. Deactivating interior motion sensor and tilt monitoring
6. Emergency function for acoustic DWA alarm
7. Combined operation with lock cylinder and remote control

Sensor Operation

The microwave sensor is a movement detector. The microwave sensor detects movement and the direction of movement (changes in distance) in the entire vehicle interior. The range/sensitivity of the microwave sensors is pre-set (depending on vehicle model and equipment).

3 seconds after the last door or hatch is closed, the microwave sensor starts its reference run.

During the reference run, the vehicle interior is "scanned". This allows any changes in the vehicle interior (e.g. objects left on the rear seat) to be recognized. A self-test monitors the correct functioning of the microwave sensors. The microwave sensors are operational 20 seconds after the start of the reference run.

Scheme 444

The 4 microwave sensors monitor the vehicle interior in zones. For this, the vehicle interior is divided into in 4 quadrants.

The microwaves disperse in the shape of a sphere.

The DWA control unit actuates the microwave sensors in the following order

The microwave sensors work in a frequency range of approximately. 2.5 GHz. The microwave sensor uses the Doppler effect to create the alarm trigger signal.

The DWA control unit in the emergency power siren evaluates the signals from the microwave sensor and triggers the alarm.

The emergency power siren for the acoustic alarm is actuated. The signal for the visual alarm is fed to the light module through the K-CAN.

The alarm system can be activated and deactivated by either the door lock or the remote control (= combined operation). In some countries, insurance requirements prohibit such combined operation.

In the event of the combined operation failing, the alarm system can still be activated at the door lock, but cannot be deactivated at the door lock. Deactivation is only possible with the remote control. The combined operation function can be encoded in the Car Access System (CAS).

Operation

The visual and acoustic confirmation for activation and deactivation is not a function of the Car and Key Memory.

The customer is able to set the type of confirmation using the Central Information Display and the controller (menu "Settings" under "Vehicle settings").

PDC incorporates the following functions

1. Acoustic warnings
2. Visual warnings
3. Check Control

The visual warning (display) is switched on in the Central Information Display (CID) as follows

1. "Settings" menu
2. "Vehicle settings" menu
3. "PDC" menu
4. Activate "Display on"

The adaptive headlights system adjusts the horizontal aim of the headlights (i.e. from side to side) in order to illuminate the inside of a bend when cornering.

The following functions of the adaptive headlights system are described below

1. System activation and calibration sequence
2. Activation of stepper motor controllers (SMC)
3. Speed-dependent analysis of input signals
4. Horizontal swivelling of the headlights by the stepper motor controller
5. Deactivation of adaptive headlight movements under extreme driving conditions
6. Deactivation of adaptive headlight movements in response to system faults
7. Setting headlights to parked position
8. Activation of automatic headlight-range adjustment by the AHL control unit
9. Adaptive headlights for automatic driving lights control

The system functions of the electrically operated seats include

1. Seat adjustment
2. Rear easy-entry facility
3. Seat heating

The fully electric steering-column adjustment comprises the following functions

1. Manual steering-column adjustment
2. Steering-column memory
3. Overheating protection for steering-column adjustment motors
