Installed a pioneer head unit and now Abs Brake and traction

I installed a new pioneer touchscreen head unit on my 2012 kk using the maestro rr interface module and ch1 chrysler wiring harness. After I installed my abs and brake light come on randomly. Only happens when I first start it up and only sometimes. When it does happen all I have to do is shut it off and start it back up and they go off. I even hooked my scan tool up to it when it came on and it said no faults and all the lights went off. Any help would be greatly appreciated. Everything on the radio and maestro works great including the backup camera I ran and maintained factory steering wheel controls. The head unit is the dmh-1500nex pioneer.

Sounds like an unhappy coincidence to me. The radio has no connection to the ABS module or to the wheel speed sensors which is where this problem usually starts.

It's so weird. The radio does have connection to the park brake and foot pedal though. But I went through and triple checked all of my connections to make sure they were all right with no exposed wires or anything.
