The causes of transmission failure are: 1. The transmission gear slips, 2. The transmission temperature is too high, and 3. The transmission oil is lack. If the fault light caused by gearbox gear slip is on, go to the garage or automobile 4S store to find personnel for maintenance.
When the car passes through high-intensity driving, it is very easy to make the transmission temperature rise abnormally, resulting in the fault light on. In this case, just stop and wait for the temperature to drop naturally; When the vehicle is short of transmission oil, the transmission fault light will light up to prompt the driver to replenish it in time. Generally, the transmission oil must be replaced and increased when the vehicle travels 50000-80000km.
If the vehicle engine fault light is on, there is no abnormal sound in the engine compartment, there is no other abnormal prompt on the instrument panel, the vehicle power is not affected, and the upshift of the transmission is not affected, you can continue driving until the 4S store carries out further investigation. The engine fault light may come on due to intake and exhaust.
The specific problems are analyzed. This engine fault light is also called EFI system fault warning light. As long as the engine power and sound are not abnormal or can continue driving. There is a program in the ECU that can replace the error. If one of the sensors fails, in order to ensure the normal operation of the vehicle engine, the ECU will replace the parameters of the failed sensor according to the preset standby parameters to prevent the vehicle from failure.
