Alarm light won’t stop blinking

I’m having an issue with my 03 tundra hoping someone else has already resolved it. My security alarm won’t stop blinking rapidly, whether the truck in on or off it blinks the same. I e also noticed that the alarm won’t go off if I suddenly hit the truck or jump on it when it’s locked. Any suggestions on what the issue might be?

 

You need to identify what alarm sensor you're talking about. Some dealers installed add-on security systems which can get flaky 8-10 years after install. They often did a hackish job installing. Are you saying the glass break sensor circled here is flashing? Or something else?

For AC/RC trucks (not DC) this is what the TVIPS (factory) system looks like installed. On mine, IIRC, that light flashes periodically, but not rapidly. And I'm pretty sure that is just the glass break sensor for the TVIPs system, nothing more.

Yes it’s the glass break sensor that I’m talking about thanks!

 

Alarm deactivated... I know the 2nd gen way how to make it stop, but am unsure if it will work with the FGTs. If you haven't done any mods, I would assume inserting key in the ignition and turning it to ON, without turning the engine over, and turning it back to off. Try this 3 times in 5 seconds, maybe this can solve the issue

 

One of the many helpful things in the 1st gen owner info megathread is links to the manual for your security system. For your system, the RS3200, that manual is here.

But there's no info on how frequently it should blink. But before we start digging on that @Icecoldex, how frequently is the light blinking? Maybe someone can give you a sanity check by comparing to theirs.

And it also blinks while driving?

Do you have a code reader to verify if there are any codes?

 

I'm also attaching this more-robust (but genericized) copy of RS3200 manual which, on page 14, shows how to test if the glass break sensor unit itself is potentially bad. I'd recommend that as a next-step.

It may just be that that unit is bad, and you need to replace the glass break sensor + LED model because it's faulty. It shouldn't be too hard to find a used one from a 2003-2006 Tundra at a junkyard.
