C1603
C1603
DTC C1603, sometimes indicated as C160300 is an OBD diagnostic trouble code indicating a manufacturer-specific fault with the vehicle chassis.
2011 HYUNDAI SONATA with 5087.0 miles
My wife was driving approximately 20-30mph, the electric power steering catastrophically failed, and did not fail over to manual steering. The steering wheel and column gyrated to an extreme level and my wife was just barely able to get the car to the median, getting a blister on her hand in the process of trying to control the wheel where she had it towed home and eventually to the dealership. The dealership pulled dtcs C1259, C1616, C1603, steering angle sensor - electrical malfunction, can bus off and derating (eps thermal protection). The mdps (electric power steering module) was replaced, but i am still very leery that this could happen again, and at interstate speeds, where the vehicle might not be controllable, as it was barely brought to the median at lower speeds.
