ARAMIS restraint system control unit

The ARAMIS control unit is used in the W204. ARAMIS is a new development that can also allow for future safety-related developments. Depending on the severity of the accident, among other things, it controls the triggering of driver and front passenger airbag, sidebags and windowbags, emergency tensioning retractors and NECK-PRO.

One belt buckle switch each acquires the belt buckled/not buckled status. A visual/acoustic seat belt reminder warning is integrated for the front seats for this purpose (Euro-NCAP countries only).

ARAMIS supports the following functions after an accident, depending on the severity of the accident:

Activation of the pyrofuse (via ignition circuit)
Door unlocking (in the event of a CAN interruption via front SAM crash sensor)
Window lowering by 50 mm
Activation of the crash-active head restraints in the event of a rear end collision
Digital crash output via chassis CAN
Activation of TeleAid (USA)
Activates hazard warning system
Engine shutoff via analog crash signal
Switches on crash-active emergency lighting

Information for Service

The supplemental restraint system control unit (N2/10) has integrated sensors. It must not be removed if the power supply is still active - airbags and emergency tensioning retractors will deploy.

Working on or with the control unit is only permitted while the battery is disconnected and after a waiting time of at least t = 3 s.
