After much BS from several dealers I have concluded that this does require a trip to the local dealership to have their little black box attached to the on board computer so that the lamps can be turned off. They call their black box a DRB "Diagnostic Reader Box". Before 1996 this is a DRBI which I believe was the precursor to the OBD systems that are currently used. The only dealer I talked with that knew what was causing the lamp to be on (talked with 3) wanted $45 to reset it (plus undisclosed sums for other things that they may find with their black box once they hook it up). I have personally elected to remove the bulb since it doesn't impact the operation of the engine.
(A different remedy is take it to an auto parts store. Most can diagnose the problem and reset the light. Those lights are there for a reason. By removing the bulb or ignoring it larger problems can occur. Machineryman)
