Even you reset its going to come out again until you didn't fix the problem. To reset, you need the OBDII, or you can do it in the battery by removibg the negative terminal and turn the key ON don't start the car, then just make a spark on the battery by touching fast the negative cable to the negative of the battery, now turn OFF the key, then, spark it again until no more spark, then put it back the cable to the battery. This is not adviceable according to the dealer.
