Re: EBCM won't separate from pump - Finally an answer and success!
At long last I can finalize this thread. I was finally successful in removing the EBCM from the pump today (not like I have been trying non-stop 24/7, but this is the third extended try). I did it by using a small pocket knife in the top left corner and wedging it between the two pieces and then, while there was a crack there, inserting a stub screwdriver in the opening thus giving me a little leverage. It did not "pop" off but required more pulling and wedging, but finally came out. Hallelujah! Now I can send it in to get repaired.
I hope this might help a couple of others that have had the same problem.

I am posting this in hopes it will help someone who hasn't done it before. I know it would have helped me (along with all the other great help I got from this forum :thumbsup:)
A flexible extension for your small socket wrench is helpful. Also, you'll need a Torx bit for the screws. Be careful removing and replacing the screws as they are a bit "tender" if corroded. See my other threads in this forum on this subject if you have trouble removing the unit (like I did).
Here's the ABS Pump #1 and the EBCM #2 diagram.
Here's the EBCM (from inside the wheel well - wheel and splashguard removed) with the large plug, retainer, swing down retainer removed. The larger circle is where the plastic retainer goes. The smaller circles are the 6 torx screws to remove the unit. Do not take out the 4 front screws.
The front pipe in this picture is for the air pump and was removed from the hole (arrow) and pulled aside for easier access to the EBCM. The larger circle (top) is the plastic position retainer for the large plug (see picture #2.) It pulls out to the left and is on a plastic string connected to the plug.

The swing down plug retainer. Swings down and clicks in place to make sure the plug stays put. You can remove this easily when you send it in to get repaired.
