Control module





General
The DICE control module is located above the main relay board (LHD) and adjacent to the main relay board (RHD). It is connected to the system components with a 70 pin connector.
As the central unit in the DICE system, the control module checks and controls the system components and functions as follows:
^ DICE - controls the power supply to the various system functions. Power is supplied directly via the control module and via external relays that are grounded through the control module.
^ DICE - is connected to the instrument bus (I-BUS) and consequently receives, processes and sends information (communicates) over the bus with other systems (control modules) in the car that are connected to the bus.
^ DICE - has an internal diagnostic function and diagnostic trouble codes are generated in case of faults.
^ DICE - is programmable. Certain functions can be programmed to meet with legal requirements, market demands, customer requirements and the car's equipment. Bus Communication
