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.

Vanliga symptom

  • ACC unavailable
  • Forward collision warning off

Typiska orsaker

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

Vilken scanner behöver du?

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

Använd live-data och freeze frame innan du byter delar. ABS-, SRS- och U-koder kräver oftast en fullsystems-scanner.

Diagnostiktips

  • Spara freeze frame när koden först sätts
  • Rensa koden först efter att orsaken är åtgärdad
  • Kontrollera relaterade väntande koder
  • Verifiera batterispänning över 12,4 V innan du misstänker sensorer
