The SES (service engine soon) light generally requires a Workhorse tech to clear it throughtheir diagnostic computers. That said however, some chassies SES lights are cleared by simply disconnecting battery cables from the battery for a short time.
If it's a "Change Oil" notice, turn the key on and press down on the gas pedal all the way 3 times in 5 seconds. Turn the key off and then turn the key back on. The message should disappear.

Just turn the key to ON but don't start the engine. We've got enough blown engines
in this group.
Olley, I know you knew this but just in case there's another guy like me out there - let's hope not.
