What is the reason for the failure of Buick's auto start-stop system?
1 Answers
The failure of the auto start-stop system in the new Buick Excelle can be caused by various reasons, such as low battery charge, excessively high temperature, pressure in the brake system dropping below a certain point, or extreme outdoor temperatures. In these situations, the start-stop system will not activate. It is recommended to visit a 4S shop for a computer check. The relevant details are as follows: 1. Function: The engine auto start-stop system automatically shuts off the engine when the vehicle comes to a temporary stop (e.g., at a red light) during driving. When it's time to move forward again, the system automatically restarts the engine. Its English name is Start/Stop, abbreviated as Stt. The Stt intelligent fuel-saving system is a set of controls for engine start and stop. 2. Principle: The working principle of the start-stop system is that when the vehicle stops moving due to congestion or at an intersection, and the driver presses the brake pedal and shifts to neutral, the Start/Stop system automatically checks: the engine is idling and not in gear, the wheel speed sensor of the anti-lock system shows zero, and the electronic battery sensor indicates sufficient energy for the next start. Once these three conditions are met, the engine automatically stops.
