Just participated in my first SCCA solo event in my 04 z06 in SSP

first two runs where good then BOOM ABS message, Service traction control, stability management all pop up and the traction control button stopped working. Car felt like I was driving on ICE around the corners very skittery everywhere.

I pulled the codes and noticed stop lamp control circuit checked the brake lights and sure enough they don't work. turn signals running lights and so forth do but no lite change on brake application. I checked my wiring for the trailer lite hookup and the green wire had melted and shorted to the exhaust, cut it out cleared the codes and they came back, car had the same issues.

Note : while starting the car after the codes were clear the ABS pulsates very very noticeably if you hold the brake while starting almost as if its doing a test and failing miserably.

Codes are :

P1574 stop lamp control circuit
1227 LR excessive wheel speed variation
1291 open brake lamp sw contacs during deccel
c1277 requested torque signal ckt malfunction
p1689 traction control delivered torque output cir

i'm thinking the electronic brake control module is fried or i need to investigate my wheel speed sensors more thoroughly.

Any thoughts ?
