The Great Wall c30 small wrench flashes and doesn't catch fire. What happened?

Pacific Auto Network saw the yellow wrench indicator light flashing on the dashboard, reminding users that the vehicle should be maintained. It doesn't matter if the car doesn't catch fire. The reasons why the car can't catch fire are battery dead, lack of oil, damage of spark plug or ignition coil, failure of electronic throttle or idle motor.

Wrench is the most commonly used tool, so it is also used as the icon of indicator light. Generally, in the program of on-board computer, when is the next maintenance time, which is automatically calculated according to the specified mileage or service time. Once the mileage or time reaches the set value, the yellow wrench will light up. As long as the vehicle is driven for maintenance, the service provider will eliminate the yellow wrench icon after completing the maintenance operation.

The battery of a car is low in charge or oil, which is the easiest item to check and the most likely reason why the car will not catch fire. The way to judge the low battery power is to turn the ignition key to the on position, press the start button twice without stepping on the brake, turn on the headlights, and then press the horn. The sound of the horn is obviously weaker than usual, or it doesn't sound, so you can judge that the battery power is low. (Photo/Text/Photo: Pacific Auto Network Wu Jiahong)
