Control Module



Control Module







General
The control module in the TWICE system is placed under the left-hand front seat. It is connected to system components via a 70-pole connector.

The task of the control module, as a central unit, is to monitor and control the components and functions in the system, as follows:

^ TWICE: controls the power supply to the various functions in the system. Power is supplied direct via the module and via external relays which are grounded through the module.

^ TWICE: is connected to the instrument bus (I-bus) and thus receives, processes, and sends out information (communicates) via the bus with other car systems (control modules) connected to the bus.

^ TWICE: in the event of a fault, stores the diagnostic trouble codes (DTC) which can be read using the diagnostic instrument (Tech 2).

^ TWICE: is programmable. Certain functions can be programmed to meet legal requirements, market demands, customer preferences, and car equipment.
