02 avalanche evo one

0 votes
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?

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).
