First, I am assuming 762mm meant C0265, not P0265. Secondly, I just wondering if these codes C0241,C0242, C0245, C0251, C0252 are symptons of a faulty EBCM? Is there anything I should look at, before I just go rebuilt my EBCM? Or worse yet replace it?

 

Before getting to wrapped up in electronics, check your vacuum lines.

I just did this one my 2000 Blazer. Brake and ABS lights were coming on
intermittently. A local "brake repair" shop read codes and decided I needed a
new computer. $1300 for that. But the problem was a crumbly piece of
vacuum hose. I'm sure they would have changed that piece of hose - after
wiping off the brake controller... It cost me $3.65 to repair the problem.

 

Check your vacuum lines.

Replace anything that looks dry or crumbles when you bend it.

 

OK, got my abs module back today and reinstalled it. Had it rebuilt from cheapabs.com, because they were close and seemed trustworthy. Took it out for a drive and no abs and brake light on. Since it was intermittent problem, one has to hold there breath first.
