U05B6Invalid Data Received From Front Radar Module B
- Generic OBD-II code · Network
- How the car detects it
- Letter B on a front radar points to different hardware depending on the brand. At Mercedes-Benz, U05B655 on the 2026 CLA electric marks implausible data from the front radar on the outer right, again with sub-code 55 for a sensor that was never configured, and it shares the remedy of the left unit: calibrating control unit N62/5 per LI54.71-P-080345. Stellantis gives B to the long-range radar behind the front bumper: on the Grand Wagoneer, lost communication U02B5 in the central ADAS module came from connector D1082A not being latched (STAR S2208000105). U05B6 itself means that module B keeps talking while its object or status data are rejected. Adaptive cruise, collision warning and lane centring then go offline; the engine lamp stays dark.
