If you do not care to find out what the code number is XXXXX set the light then all you need to do is remove the negative battery cable for a few minutes and this will clear the memory out of the computer. If the light comes back on immediately or within one or two key cycles then there is what is called a hard failure code. This means there is a malfunction still existing in the system. If you can get to an auto zone or other parts store they do free code reads and I can assist you further at that point with a particular code number.
