TRIP COMPUTER - 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) also 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 TRIP electronic module uses these signals to process information on instantaneous and average fuel consumption, range, average speed, Km travelled, duration etc.

The Trip Computer SET button, located in the steering column switch unit H005, sends an earth signal to pin 8 of connector A of E050.
