Double Beep/Alarm System Codes

[SC-986]

I'm hoping someone has had some experience with these series of alarm system trouble codes. I just purchased an '04 S. Using an Autel scanner I found the following trouble codes:
60 - central locking limit position lock not reached
34 - passenger compartment monitoring sensor
54- radio receiver faulty

20 seconds after locking vehicle with the remote I get the double beep. I've verified that all doors and compartments are secure. With the window down and the alarm activated, when I reach in through the window and unlock the car door the alarm sounds.
When I reach in as if to grab something out of the car the motion sensor is inop. and the alarm does not sound.

The red flashing light at the center of the dash does flash when the alarm is activated.

The Autel scanner gives me a part# for the defective part, that being the Immobilizer, however, I'm not sure of the accuracy of that feature of the scanner.

Any ideas?
