Description and Operation

Description

• The front impact sensor (FIS) is installed in the upper part of the side panel in the front end module (FEM). These are passive sensors that detect acceleration caused by collisions at their installation location.
• The main role of the front impact sensors (FIS) is to signal a collision by sending acceleration data to the SRSCM.
