08 Scenic stalled while driving, then it wouldn't start. It will take a while to hit.

Sorry, recently busy, did not go on Baidu, it is estimated that at this time the vehicle has long been repaired, or sold;

One, replaced the cylinder gasket (suspected of flushing the cylinder leading to shaking)

Two, replace the computer (after excluding mechanical, suspected computer control, including fault codes also point to the computer)

Three, replace the wiring harness (after the replacement of the computer, the fault also suspected that the control) line problems, replace the relay line)

four, replace the idle motor (line replacement, found that it still does not work, because the air intake is idle motor control, stalling may be insufficient air supply, so cleaning throttle, replace the idle motor, the results are still not useful)

five, programming is always wrong, or even programming can not be or even dead! (Repair card here)

Enough to toss people, it seems not to find the fault point,

Looked at the whole repair process, the operation of nothing too abnormal place, but why this programming is always out of the question, the line is also changed and still out of the question a little bit unbelievable, the relay line is the implementation of the control line, I do not think it contains diagnostic line and computer communication line,

If you check the car again, or from the last point to start, the computer has been replaced twice, why such a situation, I think we should start in the communication line to repair;

Based on:

One, only the computer and the line is left, the line is divided into two pieces, the computer communication line (connected to the diagnostic computer and other computers **** to enjoy the data) and the other is to receive a signal, the computer to make a deal Then control the actuator work (such as high-pressure package ignition, injector work, idle motor work, etc.), the computer judged no problem, but after programming no problem, after driving for a period of time and then appeared, why is it like this? Failure is not always present, but the occasional occurrence, there is reason to suspect that the communication is faulty, there may be abnormal systems in the line affecting the engine computer, which is the basis for suspecting that the communication line (removing all the external add-on devices connected, and then querying the other system whether there is a fault code) to re-analyze the relationship between the fault, it is recommended to replace the communication harness test (the workload is relatively large, the cost is not low)

< p>three, the original computer design has a problem, the production batch of different computers may not match the model (special case, the maintenance angle can not be resolved, the need for manufacturers of technical support)

Suggestions: 1, another 4S store repair, need to be informed of the front of all the process and information.
