/\ appreciate the input. I've verified proper working yaw rate, steering angle and all 4 wheel speed sensors already via INPA. But at this point who knows I could have an intermittent failure of the yaw rate or ignition switch and not realize it

Too many acronyms being thrown in my head recently. What is SLS and EHC?

Reason I do not believe it to be a steering angle and/or wheel speed sensors is because the lights will turn in with out even moving the steering wheel or even driving forward 1 foot.
