B0126Driver Monitoring Camera
- Generic OBD-II code · Body
- How the car detects it
- B0126 belongs to the driver monitoring camera, an infrared camera aimed at the driver that tracks gaze and head position for hands-free and attention functions. GM uses the code: preliminary information PIC6556 (versions B to H, 2024–2025) for Super Cruise models from Cadillac Lyriq to Silverado EV lists B0126 symptom 82, stored by the module that processes camera images and often paired with B1DD0; the steps are a 30-minute disconnect, a check of the LVDS cable and finally a new camera. PIT6229 reports Super Cruise dropping out because software wrongly judged the driver's gaze to be off the road. In the EU, Delegated Regulation 2023/2590 requires distraction warnings above 20 km/h and a failure warning when the sensor is faulty or blocked. Hands-free driving is unavailable while the fault is active.
