Great Wall ss light on indicates that the vehicle's auto start-stop function is activated. Here is some relevant information about the auto start-stop system: 1. Definition of auto start-stop: A system that can automatically control engine shutdown and ignition, known as STOP&START in English, abbreviated as STT. 2. Function of auto start-stop: Vehicles equipped with the engine auto start-stop technology will automatically shut down the engine when temporarily stopping during driving. When it's time to move forward again, the system will automatically restart the engine. 3. Advantages of auto start-stop: Whether waiting at a red light or stuck in traffic, the engine auto start-stop technology can automatically turn off the engine when the vehicle is stopped, saving fuel consumption for the car.
When the S/S light comes on in my Great Wall car, it means there's an issue with the engine start-stop system. The light may illuminate because the battery charge is too low, and the system automatically disables the fuel-saving function to protect the battery. Or it could be that the engine temperature isn't high enough right after starting, or the weather is too cold or too hot, which can also easily trigger the light. Sometimes false sensor readings or software malfunctions can also cause it. I've found that battery aging is the most common cause, and the light goes off after replacing it. The start-stop system saves fuel when waiting at traffic lights, but when the light is on, it's deactivated. The car can still be driven normally without affecting safe driving. I recommend checking the battery condition. You can use a multimeter to measure the voltage, which should normally be above 12 volts. If the test is normal, go to a 4S shop to check the fault codes to avoid letting the problem worsen. Remember, regular battery maintenance can prevent issues, and generally, it should be replaced every 3-5 years.
Last time the S/S light came on in my Great Wall H6, it felt like the system was throwing a tantrum. It could be that the battery was about to fail and the start-stop function couldn't be used, or the engine couldn't shut down and restart due to low temperatures. One morning at minus five degrees Celsius, the light stayed on after startup, indicating the system was temporarily disabled. I drove for a month without addressing it, and the fuel consumption did increase a bit. Later, replacing the battery solved the issue. When this light comes on, it means the fuel-saving function is paused, but the overall operation of the car is normal and doesn't affect starting or braking. The start-stop malfunction is more noticeable during long trips—it can save some fuel but isn't a major issue. I recommend not ignoring it and getting it checked soon. If the battery's lifespan is short, just replace it; the cost is a few hundred yuan. Temperature-related issues usually resolve once the engine warms up. Driving safety comes first—if there's a problem, fix it promptly and don't delay.
