When the restraint systems trigger, certain data are written to a read only memory in the crash safety module.
The data are used for accident research purposes (no access for service purposes).
Message to other control units
The crash safety module sends a message to other control units when the restraint systems are triggered. The
following functions are performed by the relevant control units depending on the severity of the accident:
•
Switching off the electric fuel pump:
-
via the EKP control unit
(on vehicles with electronic fuel pump control)
-
via the DME control unit
(on vehicles with no electronic fuel pump control)
•
Switching off the alternator (via DME control unit)
•
Opening central locking:
> E60, E61, E63, E64
-
at the front via the body-gateway module (KGM)
-
at the rear via the basic body module (KBM)
> E85
via the general module (GM)
> E70, E93
via the junction box electronics (JBE)
•
Switching on interior lights
> E60, E61, E63, E64
via the body basic module
> E85
via the general module
> E70, E93
via the footwell module (FRM)
•
Switching on the hazard warning lights
> E60, E61, E63, E64
via the light module
> E85
via the light switch cluster
> E70, E93
via the footwell module (FRM)
•

Visual and audible seat belt warning
For the seat belt warning, the signals of the 2 seat belt buckle switches (driver's belt/front-passenger belt) are
monitored separately.
If the seat occupancy detector detects that the passenger seat is occupied, the front passenger's belt must be
inserted into the seat belt buckle. This switches off the seat belt warning.
The following situations are taken into account in respect of the issuing of a seat belt warning:
•
Front seat belt not fastened and distance driven less than 200 m
