INSTRUMENT PANEL - OPERATIONAL DESCRIPTION

The ignition-operated power supply (INT) for the instrument panel E050 reaches pin 1 of connector A via the line for fuse F37 of the junction unit under the dashboard B002; the direct power supply reaches pin 2 of connector A via the fuse line F53 of the junction unit under the dashboard B002; pin 7 of connector A is earthed (earth controlled by the Body Computer M001, pin 36 of connector G).

The instrument panel E050 is connected from pins 3 and 4 of connector A with the Body Computer M001 and via the latter to the entire CAN:

The signal for the electronic speedometer (from brake system control unit M051) arrives via the CAN network. The same signal is replicated by pin 16 of M051 at pin 7 of connector A of Body Computer M001.

The electronic rev counter receives the engine rpm signal received from the engine management control unit M010 via the CAN.

The fuel level gauge is controlled by means of signals coming from the level gauge located in the fuel pump assembly N040 - at pins 4 (positive) and 15 (negative) of connector D of the Body Computer M001 and from there via the CAN to the instrument panel E050.

The insufficient brake fluid level/handbrake warning light is lit up by a signal from the handbrake switch I040 that reaches pin 14 of connector D of the Body Computer M001 or from the signal from the brake fluid level sensor K025 that reaches pin 18 of connector A of M001.

All these signals are transferred via the CAN to the instrument panel E050.

Instrument panel E050 also contains electronic modules which control the adjustment of the brightness of the actual panel and the other controls
