U0235 on Cadillac
Lost Communication With Cruise Control Front Distance Range Sensor
U0235 on Cadillac vehicles indicates lost communication with cruise control front distance range sensor. Au7o has documented this code across 1 Cadillac model — most commonly on Escalade ESV. 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. Typical repair costs on Cadillac range from $250 to $2,500, depending on the specific model and root cause.
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
