full bulletin at NHTSA ↗DESCRIPTION Some customers may complain that the electric power steering warning light illuminates after engine start and DTC U2011:1C is stored. Zinc-plated whisker may form inside the EPS motor and trigger the DTC. However, since it is cleared when power is supplied during DTC detection, normal operation can be restored by turning the ignition OFF and then ON. Furthermore, there is no possibility of recurrence. This case may be resolved through a simple inspection or repair without the need for parts replacement, potentially avoiding unnecessary customer waiting time.
