If you unhook the battery for a few minutes it will clear, BUT if the problem still exists that caused the code in the first place, the light will come back on. Some auto parts stores like Autozone will scan the system free of charge and get you an idea of what component has failed. If you can get the code, we can help trace down the problem. But turning the light off will only help if the cause is also addressed, or it will just come back on as soon as the computer detects the fault again. If you unhook the battery, be sure the radio is turned off first so it don't go into the lock mode.
