Citroen C2 from the instrument cluster fault lights lit simultaneously

A mileage of about 12 million km configuration 4L engine, handbook transmission Dongfeng Citroen C2 car.

The person reflects: the vehicle from the process of highway driving, the fault light-weight within the instrument cluster all lit at the same time, and there is no auto pace, motor speed and coolant temperature. Take away from warmth and in some cases not begin.

Fault analysis: diagnostic Vag diagnostic toolPROXIA3 first fault reading operation of all management programs of the car to offer the following faults: the clever management box using the engine handle unit, the airbag manage unit the communication make contact with failure with the anti-lock (Abdominal muscles), the character on the fault permanent failure (P fault). Diagnostic fault information deleted, though the fault details persists.

Thought it would be the mixture meter assembly itself contains a challenge, then swap it by using a new instrument cluster assembly, although the fault doesn't vanish. Next, mix of instruments in every do the job circuit voltage and resistance checks, in particular the ability ECU Chip tuning tool supply terminal Ground terminal and VAN community cable operate terminals (3 cable terminal: data A, B, VAN) concentration on evaluation, no abnormalities were located case.

On Smart Command Box technique parameter measuring procedure, and also the resulting anti-starting process, the mix instrument, the engine manage unit, the anti-lock handle device, established the parameter benefit to be in contrast within the airbag manage unit placing parameters involved with all the SBB key programmernormal state, there is certainly no irregular uncovered any parameter values, to make sure that dominated out the possibility of management within the unit and blend meter aspect set alternatives linked to complications brought on by the fault mild is lit.

The terminal voltage profile measurements that has a multimeter measuring the engine command device connector 48V NR Al (CAN H network cable), A2 (CAN the L network cable), L1, 12, M1 (Floor terminal), K3 (ability provide pin) the clever cartridge connector 40VNR of 2 (CAN H), and the (CAN L community cable) terminal connector 2VNR1 two terminal ignition (ignition swap to manage the facility source terminals), tech2connector 2VGR1, 2 terminal (regular energy supply terminals), change is closed, open, the engine idling voltage price in the 3 states of operation, the regular value comparison with the results having a normal condition. The effects showed that no fault lights lit about the instrument cluster issue of failure can result in intelligent control box as well as the engine manage unit circuit.
