U026CLost Communication With Image Processing Sensor H
- Generic OBD-II code · Network
- How the car detects it
- U026C rounds off the GM object detection group reported by the Escalade's active safety module; GM leaves open which sensor letter H stands for. The PIT5487 series, revised from 2016 up to version F in 2020 for model years 2015–2020, shows how the code turns up next to lighting faults. Apart from camera, park assist, adaptive cruise and driver assist messages, the turn signals may flash fast and lamp body codes such as B2575 or B2605 can join, because one chafed bumper harness feeds both lamps and sensors. Such a mix of lighting and sensor faults at the front corner is the cue to inspect that harness before replacing any module. Assistance that uses sensor H stays unavailable until communication returns; no MIL.
