Technical Service Bulletin 04-006-20-3707 — 2017 MAZDA MAZDA2

Some customers may experience a TCS/DSC warning light and SCBS warning light (amber) illumination with DTC C0051:62 stored in PCM memory. DTC C0051:62 - EPS control module[when the vehicle is driven in a straight line, the difference between the steering angle (calculated by each sensor) and the steering angle (from the steering angle sensor) is greater than the specification]. This concern most likely occurs during the following situations: When the vehicle is turning in reverse, right after starting the engine. When the vehicle is going over a bump or a curb, right after starting the engine. This concern may be caused when the DSC HU/CM performs the steering center position calibration. During the learning process, if a shock is applied to the vehicle by a bump or curb etc., the steering center position may not be properly detected and creates a steering center position error. To eliminate this concern, the DSC HU/CM control software has been modified
