trailblazer dlpkgm problems

I installed a Viper 571XV and a DLPKGM in a 2006 Trailblazer this last weekend.  I have installed remote starts in about 4 trailblazers, so it wasn't my first, but it was the first time I used the DLPKGM.  The issues that my friend is complaining about is as follows.

1.  He claims to here a relay sound coming from behind the dash.  From what he explains, it is not a fast click, such as the panic being on, where the light flash relay would be going.

2.  He has also seen the Stabilitrak Off light come on for a split second and also the airbag light, they come on at seperate times, but both for a very split second and then back off.

My question is this, has anyone had any issues witht he DLPKGM?  Considering it uses the databus wire to do everything, I thought there is possibly something acting up with the module causing it to spit garbage into the databus triggering these lights and relays to go off.

Any thoughts?  I am hopefully getting the trailblazer back tonight to take a look at it again. 

Thanks

Got the trailblazer back to work on.  Checked all the wiring, everything seemed in place.

I reflashed the DPLKGM with my loader, and re-programmed to the vehicle.

I also hooked up the 2nd accessory wire, which shouldn't be related but now it does the couple second accessory on before it starts, instead of popping off right away.

I couldn't recreate the relay sounds or the lights on the dash to come on, but I will be driving it for a couple days so we will see.
