I Recently installed an Avital 4105L on a 2001 Silverado LS everything works fine but I noticed if I don't drive the truck for 2 to 3 days it won't start
When I check for a parasitic draw I'm getting .110Ma when using the multimeter. I've read that it should be no higher than .050. When I pull the 10A TBC fuse it drops to .030 The BCM is on this circuit. Further testing shows that when I disconnect the brown plug from the BCM I get the same .030. I feel it may be the 451m module that's causing the draw. Can anyone help.

If you pull the fuse on the 451M does the draw go away? That'll tell you if it's the offender.

When i pull the fuse on the 451 there's no change. I disconnected all power to the R/S and there was no change. Its only when I pull the brown plug on the bcm which contains the lock/unlock relays. I may be dealing with a bad bcm as the guage cluster goes haywire randomly while driving.
