obd2 diagnostics will give you the fault code.with the same tool erase the error cose and would turn off the warning lights.if it doesn't then it could either be an accident repaired car with sone parts missing.hope its just a code error as usually when a system develops a fault and its repaired you need to erase the error worh this OBD tool.if after removig the code the light comes on again then u have a system fault
