DTC C1201 HELP Please ABS ECU

[newfienorthca]

My scion frs is throwing C1201
Can anyone give me some direction as how to fix it?
Engine light is on. Track control light is on.
list of mods in my garage.
If its any help I recently had a C1333 rear left VSS code.
I replaced the VSS. cleared the code and it fixed the problem.
However now I have the C1201 ABS ECU code being thrown.

I've also got this DTC C1201, but I'm in the process of tuning and my evap solenoid + secondary O2 sensor aren't connected. My TPMSs aren't working right either, so tuning + inoperable TPMSs probably lead to C1201.

Have you hit you cruise control and the light is orange instead of green, then you can't get the light to go away after pressing it again?

Car is in storage. Can't work on the problem until June. Plan on checking the clamps on the evap solinoid and under the intake manifold not sure if that's the issue. I saw a thread on accessing the solinod by remoVing the AC. Hope I solve it this summer. Also throwing U0100 with C1201. Happens after driving a constant speed. Codes first showed up after dyno tune. Over 9 psi she can pop her hoses.
Yes yellow cruise control. Car goes into limp mode when code is thrown. I can clear the codes and car drives ok with cruise.

I have the same problem! Did you ever find out what was the problem? Vacuum leak?
