Lost Communication with Cruise Control Front Distance Range Sensor

Understand U0235, common causes, and the right TOPDON scanner to diagnose it.

Adaptive cruise radar/lidar sensor not communicating.

Sintomi comuni

  • ACC unavailable
  • Forward collision warning off

Cause tipiche

  • Failed ACC sensor
  • Sensor misalignment after bumper repair
  • CAN wiring
  • Dirty sensor

Di quale scanner hai bisogno?

Full-system scanner (engine, ABS, SRS, transmission, service resets)

Usa dati live e freeze frame prima di sostituire componenti. I codici ABS, SRS e U richiedono di solito uno scanner full-system.

Consigli diagnostici

  • Registra il freeze frame quando compare il codice
  • Cancella il codice solo dopo aver risolto la causa
  • Controlla codici pending correlati
  • Verifica che la batteria sia sopra 12,4 V prima di sospettare i sensori
