1999 Toyota Camry Repair Question
Mileage: No information provided.
Alarm system
IS THERE ANY WAY TO DISCONNECT THE ALARM SYSTEM! IT GOES OFF ALL BY ITSELF DAY OR NIGHT!!!!!!!!!!!
Answer
Is it factory or aftermarket alarm? If factory, I may be able to check the manual. For the mean time, use the switch on the door to lock the vehicle, not the remote until we can figure something.
What model Camry you have, LE, XLE, SE, etc. and what motor, 4 cylinder or V6.
IT IS FACTORY INSTALLED, MODEL IS ( LE ) AND IT IS A 4 CYL. CAN THE ALARM SYSTEM BE PERMENTALY UNINSTALLED?
DENISE
After reading the wiring diagrams for the anti-theft, power door lock, power windows, and keyless entry system, it is inadvisable that you unplug the anti-theft ECU. I believe all operations I have mentioned go through the ECU to work.
The diagnostic in the TSB suggests that you check the anti-theft horn (#4l) and its fuse (#1) in the picture. Here is the caveat. Do this at your own risk. We won't be responsible if any of your systems doesn't work. You may either pull the fuse or unplug the horn wiring harness. That will be safer than unplugging the ECU.

The alarm ECU and its wiring harnesses.
