Why does the Magotan not start after the auto start-stop shuts off when pressing the accelerator?

It may be because the start-stop function is turned off, or the start-stop function is temporarily suspended when the battery power is insufficient. Here is relevant information about auto start-stop: 1. Introduction: Engine auto start-stop automatically shuts off the engine when the vehicle comes to a temporary stop during driving (e.g., waiting at a red light). When it is necessary to proceed, the system automatically restarts the engine. Its English name is STOP&START, abbreviated as STT. The STT intelligent fuel-saving system is a set of systems that control engine start and stop. 2. Function: By implanting an enhanced motor with idle start-stop function into a traditional engine, the engine is completely shut off and does not work when the vehicle meets the conditions for idle parking. When the vehicle needs to start moving again, the idle start-stop motor system quickly responds to the driver's start command, rapidly starts the engine, and connects instantly, thereby greatly reducing fuel consumption and exhaust emissions.
I also encountered this issue when driving my Magotan - the engine wouldn't respond after auto start-stop shut it down and I pressed the accelerator. Actually, there are quite a few common causes. A weak battery is the prime suspect, especially older batteries used for 2-3 years - insufficient voltage makes the system stop working. The brake vacuum sensor is another vulnerable component located in the engine bay; if faulty, the system won't detect brake signals and refuses to start. It could also be due to unattained oil temperature or activated high coolant temperature protection. Also check if the start-stop fuse in the engine compartment is blown - pull it out to see if the metal wire is broken. The most annoying culprit is loose wiring connections, especially in cars with aftermarket dashcams that may interfere with the CAN bus. I suggest trying jump-starting first. If that doesn't work, scan for trouble codes. It's best to visit a dealership to check ECU computer data. Regular battery maintenance can prevent such issues.
My Magotan also had this issue before - the car wouldn't move after stalling at traffic lights when I pressed the accelerator. Here are several points I checked: The declining battery performance affects most, as older car batteries can't handle frequent start-stop cycles; Dirty sensors in the electronic stability system may misjudge vehicle status; The system won't start if the steering wheel isn't properly centered or seatbelts aren't fastened; Also, heavy battery load when AC is cooling can trigger protection. Pay attention to these small details regularly - simple solutions include turning off AC or resetting the start-stop button. If problems persist, check whether the control module program is frozen or inspect if the generator belt aging affects power supply.
