How to Solve Engine Brake Start-Stop Malfunction?

[SanSophia]

Engine automatic start-stop system troubleshooting methods: 1. It might be accidentally turning off the switch, causing it to suddenly stop working. You need to check if the system is in the on state. 2. The automatic start-stop function requires certain conditions to work, such as stepping on the brake, stepping on the clutch, or pulling the handbrake. Some more specific conditions include wearing a seatbelt and closing the car door. If these conditions are not met, the function won't work, so sometimes it's not a malfunction. 3. Insufficient car battery power, excessive steering wheel angle when parking, emergency braking, reversing, low engine coolant temperature, or throttle valve malfunction can all prevent the automatic start-stop function from working. 4. If the issue is with the internal wiring of the automatic start-stop system or some sensor malfunction, you need to go to a 4S shop for inspection and repair. 5. If the automatic start-stop suddenly starts the car while parked, it might be because the air conditioning is on inside the car, as the start-stop function will start the engine within 10 seconds when the air conditioning is on.
