Hey sir, just got the BCM in and no voltage again. Is it possible there is a short that is stopping this voltage? Is there a wiring layout to where the power is coming in to give power to that particular wire?

The wiring was attached to your questions a while back.

Did you have it flashed to the VIN number after installation?

So, there is a light blue wire that from what it looks like should have voltage, but it does not.

It was a dark green wire that feeds the relay, not blue.

Got you. Well, no voltage coming from it. Does this indicate bad BCM possibly?

Hi, on that little fuse 175, should I have continuity going through the test leads from one side to the other? If I test it I do not, but if I test voltage from one side to the other I see voltage but no continuity.

HI, sorry to retract above, but I am seeing continuity from ends when its off, but the middle test points show no continuity. Does this matter?

So, those ends I get continuity but leads in center I don’t, but when hooked up I get voltage touching leads but no continuity.

When it is hooked up. Do you have voltage on both sides of the fuse?

Honestly, I don't know, I"m just checking for voltage out from anywhere that leads to a possible issue.

You need to go to the wire I have identified for you at least 2 times at the body control module.

That's where you test, nowhere else.

It's just crazy, I'm getting no warning about liftgate being open or window. I'm guessing that wire from BCM also provides power to signal warnings as well to my dash alerts?

No, that wire only controls voltage to the relay in the fuse block.

Did you use a new or used BCM?
