What is the obd light on the dashboard?

The answer downstairs is too one-sided. Obd is an automatic diagnosis system. If the obd is on at this time, it means there is a fault code in the car. However, there are various components, such as sensors, throttle valves, cylinders and pistons. So we can only say that there is something wrong with an engine system. Third-party car networking devices can be used to scan faults, such as golo car escape and other products. And bluetooth elm327 devices.

Of course, you can also go to ssss for maintenance.
