Failure phenomenon digiprog 3: a 7160ET Chery car or truck initially intermittent flameout phenomenon, then turn off fully can not be started by the on-site inspection located no high-pressure fire, but normal ignition coil and low voltage lines. Maintenance personnel suspected harm to the crankshaft position sensor, as a result of a rescue vehicle for the autos of your same model, to resolve the problem quickly, get rid of the the rescue car crankshaft position sensor replacement, but still there's no high-pressure fire.
Troubleshooting: with Kinder detector K81 study fault codes, engine laptop or computer crankshaft position sensor open, the intake air temperature / pressure sensor cathode quick circuit, open circuit and idle speed handle limit is reached "fault memory. To prevent the interference in the historical fault codes, clear fault codes re-read, this time because the crankshaft position sensor open and intake air temperature / pressure sensor cathode brief circuit, open circuit. Use a multimeter to check the crankshaft position sensor and intake air temperature / stress sensor and the line involving the engine ECU, line neither quick circuit phenomenon, so the mechanic replaced at the same time the crankshaft position sensor and intake air temperature / stress sensor, the result is loaded The retest vehicle or can not be started.
Since the sensor as well as the line is no trouble, then it may be terrible engine ECU. This vehicle ECU fitted towards the normal commence the car, the outcomes can not be started, it seems ECU undoubtedly terrible, then replace the ECU. New ECU fitted on to launch the auto, full of this vehicle challenge has been satisfactorily resolved, didn't think the vehicle is idling less than 10min will automatically turn off, and then they will not start off the auto.
Was the very first reaction Launch x-431 is often a new ECU was burned out. A precautionary measure, decided to take away the engine wiring harness cut open the verify When completed checking engine wiring harness, engine wiring harness is completely normal, without the need of any indicators of frayed, there is no short-circuit and open circuit repair an impasse, automobile turn towards the hands of your author. Winter automobile seat which
ECU within the finish is how terrible it? I cautiously deemed. ECU harm are typically flooding, heat, powerful magnetic field interference or expertise uncommon high voltage will harm this vehicle new ECU neither flooding nor heat, power lines some time ago just for the new line, about there was no magnetic frequently only the unusually high voltage may well trigger the ECU burned out. High-voltage source and exactly where?
In general, the only moment of the induced electromotive force or generator it might generate a high voltage in the engine idling procedure, nobody any electrical plug, then only the creating capacity of your generator abnormal! So the magnetic field lines and removed the generator armature line, and place on the new ECU commence, started the auto, but the engine doesn't idle. Quickly towards the generator field terminal voltage measurement from the generator armature voltage as higher as 23V! It appears the magnetic field or coil efficiency is unstable, resulting within the output voltage is as well high. Such a higher voltage, have to lead to the ECU or other harm to electronic elements, it seems that the evaluation is right. Jinde detector K81 study the fault code for the intake air temperature / pressure sensor cathode short circuit, open circuit, replace the intake air temperature / stress sensors and generators, the engine runs completely regular, the fault is fully ruled out.
In the case of galletto v53 higher voltage for Chery cars, General ECU will retailer energy or 30 voltage signal abnormalities or untrusted like fault code Chery 7160ET there won't be a similar fault guidelines, but the car or truck ABS technique will retailer energy or 30 voltage signal abnormal or untrusted like fault codes, this automobile ABS handle unit has lengthy been negative, since the owners Xiangui not replaced, so there will not be connected for the alarm signal, resulting in troubleshoot this charge so much twists and turns.
