The control module is integrated in the main instrument and has 2 connectors, one 12-pin (K12) and one 20 pin (K20).
The control module receives information from its own sensors and switches as well as from other systems. It processes the information and uses it to control instruments and lamps. Certain information is put on the bus.
When a fault occurs, the control module stores the diagnostic trouble codes. In case of replacement, the new control module must programmed (spare part and immobilizer). The odometer reading stored in the old control module and shown on the display must be programmed into the new control module.
The instrument unit contains gauges and meters controlled by its own control module on the basis of information received from other systems as well as its own sensors. Warning and indicator lamps which are controlled by their own sensors/switches as well as control modules from other systems. All the warning lamps, indicator lamps and light bulbs (not LEDs) are replaceable.
The odometer and tripmeter display has two number registers, one with six digits for showing the odometer reading and one with four digits for the tripmeter reading.
The control module stores the distance driven and displays it. There is a lamp in the display which is replaceable.
