So the symptoms are that my ABS and TC/DSC lights will pop on randomly, they stay on till the car is turned off but are off when you turn the car back on, even if the car has been running and you turn off the engine and start it right back up, the lights are gone.
Here is the weird part.. It doesn't always come on, I can drive aggressively and it will stay off or I can drive like a grandma and it can come on.
Sometimes it comes on under breaking and other times it is during turning, other times it comes on just cruising. It has no effect on power or driveabillity it's just plain annoying.

I read the code with my cobb and it said "cruise controll/break swithch 'A' circuit malfunction"

I'm out of ideas, I've checked the sensors at the brakes and they seem fine, I don't really know what else to do?

 

Also this started happening about 3,000 miles after installing my rims and 2,000 miles after my BBK.. I don't think they are the issue.

 

My traction light flashed a few days ago going around a turn as well. Never while braking though.

 

Bump for some ideas

 

Thanks Charles, I guess I'll start checking what I can, any quick tips?

 

Check the connectors by the front wheel wall. I had this problem once. Reconnect them tightly, never came back

Or u could broke one of the señor wire when u did ur bbk. My friend broke his Lexus sensor like that, wire seems fine but it has a open circuit. Replaced, good as new.

 

Inside the wheel well?
I'll try that, I think it's something loose because it can go a week without happening.
