The engine starts by ISA or BSA. Different types of start (key start, start / stop system, coasting mode start, etc.) will not produce vibration, so the driver is almost no sense of the start. ISA or BSA can make xhorse vvdi prog the engine quickly into the idle state, or, if you press the accelerator pedal, the engine can quickly reach the appropriate target speed.
    The ISA also moves the crankshaft to a Xhorse PCF79XX Adapter chip favorable position that facilitates the start of the engine (which can be restarted many times). With this positioning, the torque compensation with dynamic control can be performed during start-up, at which the ISA will know the PCF79XX specific time of the next compression and adjust the torque required by the dynamic control function accordingly. Thereby compensating for the speed fluctuation due to the difficulty of the engine activity in the compression stage.

Through the above detection of the fault code analysis, are historical fault code, clear the system after the trouble code no longer x431 appears. Description of Launch X431 V multiple systems to record the history of the fault code is due to the previous technicians to repair the vehicle, in the case of non-standard operation, man-made fault code, and vehicle failure is not directly related.
    Static detection, read the transmission system data stream, and did not find the exception. Before the technician also replaced the transmission computer board, x431 v tablet gear actuators, clutch actuators, gear switch, gear bar TGS sensor, dashboard, junction box and check the relevant lines, etc., failed to rule out the failure. Indicating that the possibility of component damage is almost zero.

Adjust the rear trouble, order replacement headlamp control module. It is necessary to Launch X431 V 8 inch talet remind here, Mercedes-Benz LED headlamp control module, whether it is to upgrade or replace the new control module need to use special tools to scan the bumper on the two-dimensional code and bar code, headlamp control module is scanned bar code, The LED control module is scanning the two-dimensional code. In front of already said, LED headlamps are launch x431 controlled through the channel, different channels occupy the light function is not the same, you must scan the relevant two-dimensional code and bar code to distinguish between different channels, so as to the Secretary of the Job. But here you can tell us a little skill, 4S station with a CGDI Prog Mercedes Benz dedicated scanning tool is very expensive, we can use the phone under a special scanning software, the same can be swept inside the information, but sweep out A large number of CGDI Prog numbers, put it inside the box on the line.
    Fault Summary: In fact, this is a relatively simple fault cases, to figure out the functional principle is very simple, and each fault has the characteristics of each fault, but we must clarify the mystery, which solve the problem Only targeted. I think x431  through this failure we understand the new S-class full-LED headlamps and some of the diagnostic principles of diagnostic methods, this is the most important point.
