Need advice on code: TCS C1267
Can anyone help with troubleshooting error code: TCS C1267 (RR Inlet Valve Solenoid Malfunction).
As soon as I start the car, I get a "Service ABS and Active Handling" message and error code C1267.
Not sure what the Inlet valve solenoid refers to. The ABS wiring to the rear right hub looks intact.
Any help will be most appreciated.

I think the first thing to check is if the fluid is blocked in any way. So, I would bleed the brakes to verify everything is good before replacing items.
Does the car pull at all in either direction when braking?
If that looks good, I presume it is the BPMV. My understanding is that one thing that could possible fix this (this trick worked on other cars for me, but I've never tried it on the Vette) is to take the car out get it up to speed and slam the brakes to get the ABS to activate. Sometimes this gets the system to "unstick" and then start working again. You would do this at least 4 times. If the DTC error comes up again, then you need to turn off the car, clear the codes, and do it again.
I forget where I read this but I was told to do this anyway at least once a year to make the ABS go through it's paces.
Otherwise BPMV replacement can be a little expensive, and you then have to bleed the brakes again. And, I've been told you need a Tech-II to reset the EBTCM as well if you replace the BPMV.
