02 avalanche evo one

Question

I have an 02 avalanche with evo one installed. Locks are hardwired with relays in line, when I lock the truck, I get 3 flashes from parking lights and 3 chirps from siren. I'm guessing it is something with that system not recognizing the lock pulse. Is this correct or could it be something else?

Answer 1

When using the alarm features, the sytem will warn of any open "zone" upon lock.

The 3 chirps/flashes on Lock(Arm) is to indicate the module is seeing a Door open through CAN. It may also flash 3 times if ground is present o nthe PINK/BLACK upon lock (which is a dual purpose analog hood and door status input).
