Blindly disassembling the battery causes the loss of ECU information.best golf cart batteries

　　The ECU of the electrical control vehicle is the central nervous system of the control system. It not only has the control function, but also the memory function. When the automotive electrical control system fails, the computer ECU will remember the corresponding fault information. The maintenance personnel can read the fault information from the car's failure system (through the diagnostic socket), which is output in the form of a fault code. People find the corresponding causes and parts corresponding to the fault code according to the fault code.

　　If you remove the battery or battery connection cable (or unplug the power supply fuse) before reading the fault code, it is equivalent to interrupting the power supply of the computer ECU, and the failure code in it will automatically disappear. If you want to obtain the working conditions and environmental conditions when the fault information and the failure of the failure (such as: the engine speed and load of the engine under specific conditions, the water temperature of the engine, a certain air intake temperature, and some kind of working conditions related to the sensor, etc.). Obviously, this is very troublesome and time -consuming, so you must not remove the battery connection cable at will. You should read the fault code of the information before repairing the electric control vehicle before the battery disassembly and other maintenance operations.
