Enhanced Traction System (ETS)
The ETS limits wheel slip during acceleration when one or more of the drive wheels are accelerating too rapidly and the brake switch is off. T...

To inspect for this condition, measure the disc at 12 points with a micrometer at a radius approximately one inch from edge of disc. If thickness measurements vary by more than ...
