Alarm Malfunction Repaired
My problem has been fixed.......I replaced the PSE pump, problem fixed. The cost at the dealer was $770.00. If you can buy the pump for $300 some odd dollars, it's an easy job. Unplug and plug the hoses back in.

Alarm Malfunction
It's technical name is Pneumatic Systems Pump.......It's under the rear seat on the passenger side. It controls all of the vacuum operated equipment in the car.
Once my old one was taken out, my mechanic found the problem that caused it to be faulty. The contacts were somehow not making contact when activated. Once finding it, it took all of 20 secs. to fix. So now I have a spare.
