DTC Code Question

I just picked up a Superchip Flashpaq 3875 and hooked it up to the JK. I ran the diagnostics program and got 2 error codes.

Just wondering if anyone knows what these code messages really mean?
U0121 Lost Communication with Anti-Lock Brake Module
U0100 Lost Communication with ECM/PCM

If it matters, I have a 2009 Rubicon with 2.5 teraflex coil lift.

Thanks.

Was a warning light on, or just checking codes for gp?
