I guess this is where I should ask this. Straightline tuned my car on their dyno and now I've got the ABS INOP and ASR OFF lights on in my car. I assume it's from the wheels slipping on the dyno because they came on when I've done some pulls before. However, last time they turned off after like a quarter mile of driving of the dyno. This time they've been on for 300 miles and numerous drive cycles. Any thoughts as to why it's taking so long, or could something be screwed up with the sensors themselves?

 

Check the wire harness and plug above the axle on the drivers side and also the connectors on the backing plates. Sometimes they get pulled loose by the dyno straps.

 

The traction control module was unplugged above the axle. We plugged that back in and reset the codes and after driving it they immediately went away.
