2003 avalanche, viper 791xv

I am not familiar with DEI bypass modules at all. BUT when this problem pops up using Astrostart products, here is their solution.

On the ground while running between the bypass and the remote start you will need to install a relay. Tagg off of the ground while running for pins 87 and 86. 30 goes to ground 85 will get 12 volts from the pink ign. wire at the column. You MUST install a diode in line with the connection to the ignition wire. Cathode towards the relay.

Try this.

Sorry i can't quite understand what you are saying on how to wire up the relay...(it's been a long couple of days) any way you can just list it 85- 86 like that man it would save me a headache..thanks in advance

pins 86 and 87 get connected to the ground while running. between the R/S, and the bypass. (in DEI lingo it's called status output)

Pin 30 goes to a good solid ground. pin 85 goes to the pink ign wire in the harness of the truck. on the wire that connects to the pink wire and pin 85, you need a diode "in line" with the line facing the relay.

Hows that? Now remote start and do a key takeover and see if the security light is on?

Can you get your hands on a 457gw? Use this all the time on the avalanche's and gm's and never had this problem? Is the method with the inline relay supplying a true ground between the bypass and module? That what it seems like to me.....?
