Just The Basic Facts
Are you taking appointments?I installed mine yesterday. Here is a video (at bottom) running through my color. You can go about this in a few ways. The easiest is to do what PJs son did, just re-flash the BCM-B. Or you can go a more cautious route like I did, buy a second BCM-B and have it programmed, keeping the original intact. This is more work intensive but I think the safest. Also, I have the new workshop manuals from Helm. It has pretty much everything you need to know about the car and wiring in it. It does not have to be done at a dealer, anyone who has a VCM-II can program it. I'm not sure if the snap or other programmers can do it. It takes about an hour my way as you have to dis-assemble some things to get to the BCM-B. Here are the steps I took.
Buy a new BCM-B (part #13C788) $52 on line or at a certain dealer who advertises on this site.
Find a dealer or friend who has a Coupe with the same options as you and lighted sills (I doubt you need anything but the lighted sills on a premium model, the only controls in the BCM-B are for ambient, turn signal and brake lights) I chose a model that did not have adaptive cruise as it sends signals to the brake lights and may cause some conflict if you load a config from a car with adaptive cruise.
- Once you have the donor car and scan tool, simply upload the BCM-B configuration to the scan tool. (Do not mess with the BCM config)
- On your car, install the sill plates if you already haven't, they plug right in. Do not splice anything like the directions tell you to.
- Remove your BCM-B
-- Pull the weather stripping back on the right side of the trunk. (careful, it leaves black gunk on your hands.
-- Remove the spare tire cover (floor piece, you should see your air pump now)
-- Remove the Right side luggage trim panel two plastic pins. (If you don't have a trim removal tool, STOP! and get one. They are only a few bucks.
one pin is at the far back towards the bottom, and the other is near the top where you pulled the weather strip back from.
-- Remove the lower Sub Woofer trim) There are three torx screws in the bottom of the subwoofer trim panel front middle back (near the floor)
-- Remove the subwoofer and amp (one unit) by taking out the two bolts on the floor and torx screw at the two oclock position
-- the Amp will be able to be tilted forward so you can reach behind it and disconnect the connector under the amp back bottom(there is a release in the back middle of the connector, pushes in easily) now set the unit aside.
-- Pull the grey trim out of the way (you don't need to remove it) you will see the BCM-B, Pull off the two plugs (release is in the back middle)
- Plug the connectors into your new BCM-B
- Go through the steps to program a new BCM-B from the scan tool.
- Check your sill plates to make sure they are working in my color. check you turn signals and brake lights.
- If all works well, swap out BCM-Bs
-- loosen the two nuts, slide it up and out. Now you can remove the nuts without dropping them into the rear quarter.
-- Put your new BCM-B in
- Put everything back in reverse order.
If you don't want the extra BCM-B, just do the programming part, no need to tear up your trunk. Again, I would get the donor config from a car without adaptive cruise.
any lighting errors are from the camera, the lights work flawlessly.
