Nevermind my last post. I discovered that there were two bulbs that were blown. The PAD "off" indicator light and the Air bag warning light on the instrument cluster, the latter which was causing the incessant 5 beeps...for 5 cycles...EVERY 30 MINUTES!!!. I repaired the swapped the light on the cluster with the 4x4 light and it started displaying the 2 7 code. I then took out the module for the on/off switch for the passenger air bag and....felt really stupid! Put the new bulb in, purchased from Radio Shack, and everything works great. Thanks a bunch for a great forum. Now if I can just get rid of a misfire on my #6 cylinder everything would be great. But that's a battle for another time.
