It goes off if I use the fob or the key. It engages about 10-15 seconds after locking and goes off for about 15 seconds, then stops. I can't figure out how to stop it. It happened after I disconnected my battery to reset my ECU because I had throttle problems.
It's not the main Honda alarm where the hazard lights start blinking furiously and the horn starts beeping, I think it's some aftermarket alarm I didn't install. It seems like the siren speaker is coming from the rear near the tailgate, but in a grill type vent I can't seem to get off or access behind.
Can anyone help me?
