I repaired my EBCM about 3 years ago. Pretty much right before the pandemic started. I took plenty pics and I was going to do a write up, but my phone crashed shortly afterwards and I lost ALL the pics. I suspect it had something to do with my wife repeatedly dousing it with Lysol. Regardless, I did remove it with a T27 I believe, T25 had a bit of wiggle and I was scared I would strip them out. Thankfully I didn't strip any screws. I did however strip one of the T5 (or was it T7) screws that you unscrew to actually open up the EBCM to repair it. After removing all the screws, you slowly cut the seam/rubber sealant all around it with a very sharp razor blade all while SLOWLY prying it open. After I got it open, I reflowed the solder on each of the relays and every solenoid. Then I sealed it back together with RTV, put the screws back in, and re-installed it in my truck. Not one single ABS light or code ever since.
I feel bad because I took a LOT of pics, from everything to removing it, to the fastener size, to cutting it open, reflowing the solder, then putting all together again. I felt it was pointless to do a write up with no pictures. Also, I do have an "L" shaped module, but which version, I'd be lying if I told you.
