Default Ebcm?

I have been working on this for a week now. ABS light and active handling light comes on just after take off but resets each time the engine is shut off.

service ABS
service active handling
service traction system is displayed

codes set are
TCS 1232H 1233Hand C1248 HC
first two are both ft when sensors . Not sure the last one and if it is what sets the first two?

trying to avoid chasing rabbits. Brake fluid fine, checked all week sensor connectors and ran all the harnesses I could for breaks and bad connections. All seem fine.
both ft sensors check out for AC currant when unhooked and wheel spun.

any TS ideas from here? No code for EBCM but based on writing diagrams everything feeds through there?

One of those threads suggested new wiring harnesses for the front abs sensors. If those are still available it might be a relatively cheap fix.

Another thread said that absfixer couldn't fix this, that it's a vehicle wiring problem... But it wouldn't hurt to check with them to see if they still feel that way. Because another thread said that a new ebcm solved the problem.

If a new ebcm does fix it, and this one can't be saved, please send me a PN, as I'd like to buy a slightly defective one. I want to try to figure out how to modify the firmware to solve a problem that comes up with C5s in autocross and road racing, and I need one to experiment on.
