CITROEN C5 X7: PROBLEME DE COMUNICARE

Mesajde Andrew299 » Vin 13-Aug-2021 13:28

Buna ziua! A intampinat cineva problema urmatoare si a reusit o rezolve?

La coborarea unei pante lungi in frana de motor, imi apar erorile de gearbox fault, engine fault, esp abs fault, auto parking break deactivated iar motorul se opreste. O lista lunga de DTC-uri cu multe erori de CAN communication si semnale neprimite.
Se intampla doar cand cobor mult in frana de motor. Daca sterg erorile totul merge ok. Masina in rest merge bine si are putere.

P0472
Codurile sunt de pe un tester multimarca (descrieri in rusa) dar aceleasi apar si in diagbox (nu am descrierile din pacate)

Am fost la un electronist dar nu a reusit nici el sa afle momentan despre erori. A verificat conectori, rezistenta CAN, conexiuni, sigurante dar nici o rezolvare.

Am nevoie de ajutor

Am primit niste informatii despre aceste coduri de eroare pe forumul strain:

U1213: Intersystem CAN network: One of the parameters present in a frame emitted by the ABS/ESP is invalid. Communication fault between ECUs detected for 3 secs
Symptoms: Engine hesitating, cutting out, Lack of power, Starting problem.
Suspects: Engine ECU, Intersystem network

P16A0: Engine: Detection of runaway caused by oil ingestion after stalling. Monitoring that the engine is not racing by burning its oil instead of fuel. The fault is recorded if, when there is no injection, the engine speed exceeds 6000 rpm for 2 seconds; The total turbocharging exceeds 8000 mbars; The mixture is below 1,1 for 0,5 seconds and the engine speed increases by 300 rpm.

Happens when accelerator pedal position is with foot lifted and not at idle.
Downgrade Modes: Deactivation of the traction control, Performance of ESP settings impossible, Deactivation of the pilot and post-injection injections, Deactivation of the request for regeneration of the particle filter from the diagnostic tool, Request for closing of the EGR valve, Deactivation of the EGR function, Prohibition of regenerations of the particle emission filter and stopping of those in progress, Request to switch off the engine immediately, Request for emergency closing of the turbo air cooler by-pass unit, Request for emergency closing of the throttle, Deactivation of taking account of the ESP torque settings, Irreversible deactivation of the vehicle speed limiter (Need to switch the ignition off and then on, in order to make the function available again), Irreversible deactivation of the vehicle cruise control (Need to switch the ignition off and then on, in order to make the function available again).
