Sometimes the manufacturers code the vehicle's computer to come on to remind owners it is due for servicing. Disconnect the negative battery cable for about 15 minutes. This should reset the computer and cause it to initiate a diagnostic cycle. If the light comes back on, check the fuses. My car blew a 40 amp fuse each time I hit the brakes too hard, causing the light to come on. Although it is not recommended, I changed it to a 50 amp fuse and the light never came on again.
