Just remove the negative battery cable and turn on the switch to drain any leftover power stored in any compacitors. Replace the cable and you are good to go. If you still have a service light then you have a legitimate problem.
When you disconnct the battery, you are going to have to reset a number of functions that have been stored by your computer. The better way to go is to purchase or borrow an OBD II Scanner or reader. This allows you to see what the trouble code is at the same time being able to reset the service light. By the way, these scanners are relatively inexpensive and it's an excellent tool to own. The scanner has a simple one-plug attachment and it fits into the scan port under the left-hand side of your dash. It walks you through each of the steps required. I had the same problem on my 2005 Explorer and by using the scanner, I was able to shut my light off in a matter of two minutes.
