Why did Jiangling Yusheng s350 stop when the brake was released automatically?

Automatic gear braking will automatically shut down the engine. This is not a fault, but the automatic start-stop function of the engine. If there is no automatic start-stop function, it may be because the brakes are too urgent. Although stepping on the brake gearbox will automatically downshift, it will cause the car to stall because the reaction speed of the overspeed gearbox is too fast.

1. First, check whether the brake vacuum booster system leaks air (air inlet, vacuum tube, check valve, vacuum booster) and replace defective parts.

2. Check whether the engine works without cylinder. Check the cause and replace the defective parts.

3. The computer detects that the throttle opening (idling, air conditioning off, throttle opening should be less than 8 degrees) is greater than 8 degrees. Clean the throttle and make basic settings.

4. Check whether the brake light switch is normal. Replace defective parts.

5. If it is not good, check the automatic gearbox.
