Why did the Mazda auto start-stop suddenly stop working?

[VonLondon]

Mazda's engine auto start-stop function's normal operation is related to battery charge, air conditioning set temperature, engine water temperature, and whether the seat belt is fastened. When the battery charge is too low, the engine computer will automatically prohibit the start-stop function from activating. Below is relevant information about auto start-stop: 1. The auto start-stop device allows the engine to temporarily shut off when the vehicle comes to a temporary stop or stops at a traffic light. When starting to drive again, there's no need to operate the ignition switch key as the engine will restart automatically. 2. For the auto start-stop to function normally, certain conditions must be met, such as the driver fastening the seat belt, the driver's door being closed, the gear lever of manual transmission vehicles being in neutral position, and the clutch being operated. If these conditions are met, the start-stop device automatically engages the engine. Therefore, a malfunction in the start-stop system isn't necessarily due to the system itself but could be because the conditions aren't met or there's a fault in another system.
