DescriptionThe Trip Computer function is activated via the special switch located on the right lever of the steering column switch unit or directly on the instrument panel (depending on the version). To manage the calculation and display of Trip Computer information (General Trip and Trip B), the instrument panel acquires the following signals from the B-CAN network:odometer signal;vehicle speedinstantaneous fuel level, with the relevant sensor fault signal;The Trip Computer information displayed on the instrument panel is in the following order.General Trip:RangeJourney distanceAverage consumptionInstant consumptioinAverage speedJourney timeType B (partial):Journey distance BAverage consumption BAverage speed BJourney time BTo reset the trip recorder, press the 'reset' button on the steering column switch unit (or on the instrument panel, depending on the version).
Functional description All the information for the 'Trip computer' function is displayed on the LCD display contained in the instrument panel E050. The body computer node M001 provides the instrument panel with the ignition-dependent supply (pin 3 connector N) and direct battery supply (pin 1 connector N). All the useful information for managing the 'trip computer' function is transmitted via CAN from the body computer node M001 (pins 35, 36 connector I) to the instrument panel E050 (pins 7, 8 connector A).The signals transmitted from the body computer node are:fuel level, supplied by the electric pump N040 (pins 1, 2);vehicle speed signal, supplied by the ABS control unit M050;engine rpm signal, supplied by the engine control unit M010 via the CAN network to the body computer node See E5050 DIESEL ENGINES ELECTRONIC MANAGEMENT .The TRIP electronic module uses these signals to process instantaneous and average fuel consumption information, range, average speed, mileage, duration etc. Via the key located on the steering column switch unit H005, the negative signal is sent (referred to earth C020 connector B) for the change of menu in the display of the trip computer information.767Earth C020 is located on the passenger compartment floor and located near the right front wheel arch (footwell).
