Service bulletin MT-002-20

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

04-003-19-3589a2019-07-01. Service bulletin. Some vehicles may experience the TCS/DSC indicator light and the TPMS warning light both ON with DTC C0051:62 stored in memory. DTC C0051:62 - The difference between the initial learned value of the steering angle (as calculated by each sensor) and the steering angle (as calculated by the steering angle sensor) while driving in a straight line, has exceeded its allowable tolerance (or threshold). NOTE: For vehicles equipped with the Smart City Brake System (SCBS), the master warning light also comes ON with the message "SCBS Inspection Required" in the display. The symptoms may occur when the following conditions are met: After starting the engine, the vehicle is driven backwards while the steering wheel is turned to the left or to the right or going forward over a bump while turning the steering wheel. The vehicle is then driven forward and begins accelerating while the steering wheel is still turned. To eliminate this concern, the DSC HU/CM software has been changed.
