looks like you have had water intrusion in the past from the orange rust located on the body paint in that area of your pic.

 

That could cause a problem if there were bcm codes.
Look @ tapped wires, AM alarm blocked oem rke.

 

Why do you need videos? This scanner has the same capabilities of the Tech2. Just plug and play, navigate. scan all modules, look at live data..etc...

 

Ok… another solid reason to purchase this scanner if your a true DIY’r like most of us..
Went to replace front brakes on the Ole’ 06’r H3 today.
What was supposed to be a quick pad slap and caliper service turned into and entire front brake replacement…. Pads, 2 Calipers and 2 rotors.
As life would have it, it appears the front calipers were not working at all and I am suspecting that 50% of the pistons were seized.

 

Turns out, you cannot bleed the brakes on the H3 without a scanner to perform the auto brake bleed for the ABS module which by chance is part of your Master cyl… another genius idea by GM…
thankfully this scanner proved its worth again!

Thanx HummerZ !!!!

Anyway, I'm waiting for a question to be answered on my BCM before I tackle that one.......


I took mine out today for the first time to check. Simple to remove, 2 bulk connectors and the antenna connector + you need to remove the push pin clip from the lower connector and 1 push pin clip holding the bcm to the interior panel. Slide out after that. Take the board out of the housing, I only used my thumb to remove 1 retainer clip at a time to release all. BCM case opens like a book, then the board comes out. Then shower the board and contacts with CRC® QD® Electronic Cleaner and let it dry. 1 thing I did notice on a few connector contacts on the bcm was oxidation, I gave them a resurface.
Funny thing, after install, I walked away and went on to other things, then noticed my emergency flashers were on. I checked the switch off/on still flashing. Started it up, and passlock was on along with flashing emergency lights, then all went off.
Note to self, after disconnecting/reconnecting BCM:> start up.

 

You do not need a scanner to bleed the brakes.

 

Actually, you do if you remove lines from the ABS module to replace them thus losing all the fluid or if the reservoir runs dry.
A scanner with ABS bleed came in quite handy when I needed it. Didn't even know my scanner had that feature until I investigated in the owners manual.
