C5Z Track Car - ABS Issue
I have a problem with my ABS in my 01Z that is 90% track only. The code points specifically at the Left Rear Output Solenoid, and the ABS hasn't worked for half the year. I just tracked without it and figured I'd fix it over winter.
I'm not entirely sure where to begin. Anyone have any insight on how to troubleshoot that particular solenoid valve and fix the issue? Or does the ABS unit to be replaced? I've already checked for any loose connectors and serviced any grounds associated with it.

I had a similar issue happen last year on my track car. It had error code C1267, Right Rear Inlet Valve Solenoid Malfunction, and the brakes would lock up. I sent an e-mail to absfixer.com and asked if they could fix it. They said they could and said they see faulty solenoids on track cars. I sent the my ABS computer to them and they replaced several of the solenoids (the silver round cylinders on the non-connector side of the ABS computer). I haven't actually installed the repaired ABS computer back onto my car as I had already installed a new one due to an upcoming event (the new ABS computer fixed the problem). So my suggestion is contact absfixer.com or figure out which solenoid it is and replace it yourself if you are able to do so.

If anyone else has any suggestions, or has replaced one of these valves...I'm all ears.

I had one car that was really over-cooked it's brakes a couple times and ultimately it ended up damaging the seals in the ABS valve body - we ended up replacing the valve body.
If the code says a valve is sticking it may be in the valve body itself - I used to see complete units (both the valve body and the module) - but it doesn't look like there are any up at this time.
If you didn't get your brakes super hot hopefully it's similar to the situation above but if you know you've cooked your brakes this may help.
