U059CInvalid Data Received From Drive Motor Control Module C
- Generic OBD-II code · Network
- Can trigger limp mode
- How the car detects it
- A third drive motor controller exists only on tri-motor or quad-motor vehicles, where one axle carries two motors for torque vectoring. Examples are GMC's Hummer EV in tri-motor form and Rivian's quad-motor R1T with a motor at each wheel. U059C is stored when module C still talks but sends torque, speed or status values the vehicle controller cannot accept. Which wheel or axle module C serves is left to the maker, and none documents U059C publicly. The sibling logic is the same as for module B, which Audi treats as the rear drive unit on the e-tron and GM monitors with counter and authentication checks; for C the vehicle usually disables the motor and continues with reduced power and without torque vectoring on that axle.
