Alarm LED flashing?


Recommended Posts

This started happening a few days ago: Lock the car with the remote. LED alarm doesn't flash for about 10 seconds, then flashes 21 times. After that it flashes normally (if I recall correctly). Today it's doing the double-flash, so there is something unlocked or broken (the alarm control was replaced when I bought the car).

Is it flashing a diagnostic code?

Looks like I'll have to get the diagnostic readout for the other problem, but I'd like to check the main connector first. Is the alarm control under the drivers' seat?

Thanks.

Many of the flashing are normal responses to key presses on the remote.

I would start with a new remote battery - if you had an open zone you would hear the horn beep when locking.

The remotes are new, replaced when the new alarm control was replaced, so I assume the batteries are new too.

But I'll try new ones anyway.

I'm now getting double flashes, that I thought meant there was something open, but no horn beep.

The range of the remotes has always been really short. Ten feet at best. Might have to try the range

mod.

You might want to test that your alarm horn works. They frequently fail...
