driving away fro hotel this morn and about 5 minutes into trip the theft alarm light in the center of the dash right up under the windshield started to falsh continuously. a few minutes later the alarm horn went off for about thirty seconds then stopped. Light continued to flash steadily. Horn went through its thirty second cycle again and I could hear a relay behind or beneath the dash chattering rather rapidly. It was not the four way flashers. this went on for about thirty seconds then quit. The theft alarm went out. All is well. No sign of the car having been tampered with. Same routine for locking and unlocking used I have used for the last eight years. Fuses are good.
any guesses as to what would cause that sequence of events?
