Emergency-Running Characteristics
WARNING: This page does not describe the selected car, but rather 46 other vehicles, including the 2008 BMW M5, 2008 BMW 650i, 2007 BMW Z4, 2007 BMW M6, and 2007 BMW M5. However, it is still accessible from the selected car via links, so may be relevant.
The footwell module has the following emergency-running characteristics:
- Power Supply Failure:
The footwell module has two terminal 30 power supplies.
If a terminal 30 fails, the following lights will be actuated:
- Front lighting: Dipped headlights and parking lights (one side of vehicle each)
- Rear lighting: The side lights and outer brake lights are actuated on one side (parking lights). The inner rear lights are actuated on the other side of the vehicle. The vehicle thus remains lit on both sides. It is thus impossible to confuse the vehicle with a single-track vehicle (motorbike).
- Brake lights: The brake lights are actuated with normal brightness on one side of the vehicle (encoding-relevant "European version"). This allows "single-track braking", as if, for example, a single brake light had failed.
- Processor Failure:
If the processor fails, the system will switch to emergency operating mode. Emergency operating mode is a hardware feature and thus completely independent of the footwell module.
Emergency-Running Characteristics If The Processor Fails:
- Vehicle lighting: The following are switched on when terminal 15 is switched ON: At the front the dipped headlights, and at the rear the position lights and the left and right outer brake lights (side lights).
The position lights and the left and right outer brake lights are not dimmed to 10% brightness, as is usually the case, but rather operated at full power.
Vehicle lighting is thus assured, regardless of the position of the light switch.
- Brake lights: When terminal 15 is ON, the brake lights (left and right) are switched on when the brake pedal is depressed. A direct wire connects the brake light switch to the footwell module.
Malfunctions In The Event Of Processor Failure:
- No turn signal, no hazard warning lights
- No main beam, no headlight flasher
- No front foglights, no rear foglights
- No additional centre brake light
- No communication via the K-CAN
- No communication with the trailer module
- Vehicle lighting: The following are switched on when terminal 15 is switched ON: At the front the dipped headlights, and at the rear the position lights and the left and right outer brake lights (side lights).
