2011 115k. After 1 hard brake event abs and brake dash lights always on. Odd braking ever since like rolling forward seconds after a full stop. Techstream shows c1246 dtc 204, and yellow highlight on stroke sensor readings. New to techstream so looking for confirmation I am understanding the screenshot. The yellow measurement shows v1.72 and I assume the non-yellow measurement v1.70 is the prior normal at rest reading. Does this mean the sensor is bad or shifted and needs recalibrate?
