System Components

The SIA IV system consists of the instrument cluster, the engine control module and the stability control system (ASC/DSC). The instrument cluster contains all of processing electronics and the SIA display in the odometer area.

The stability control system supplies the road speed signal and the engine control module supplies the injector on time ("ti") signal via the CAN-Bus.
