U0235 on Lexus
Lost Communication With Cruise Control Front Distance Range Sensor
U0235 on Lexus vehicles indicates lost communication with cruise control front distance range sensor. Au7o has documented this code across 1 Lexus model — most commonly on LX. This network (U) code means a module has stopped receiving the expected messages from the cruise control front distance range sensor (the forward radar/sensor used by adaptive cruise control). This sensor, typically mounted behind the grille or bumper, measures the distance to vehicles ahead to maintain following distance. When communication is lost, adaptive cruise control and related features stop working and a warning is displayed. The fault is usually in power, ground, wiring, or the sensor itself.
Common Causes of U0235
- •Loss of power or ground to the distance sensor
- •Wiring or connector fault on the bus circuit
- •Faulty cruise control front distance/radar sensor
- •Corroded or damaged connector
- •Blown fuse feeding the sensor
- •Sensor blocked or knocked out of alignment with internal fault

- 12.3-inch Infotainment / Lexus Interface Screen Freezing, Rebooting, or Going Blank2022-2025
Owners of the current-generation LX have reported the center infotainment display freezing, rebooting, losing audio functions, or going black temporarily. Complaints and forum posts describe navigation, camera, and climate-related interface interruptions, sometimes resolved only by an ignition cycle or software update. The problem appears tied to head-unit software instability rather than a single hardware defect in many cases.
