Lost Communication with Throttle Actuator Control Module

Understand U0107, common causes, and the right TOPDON scanner to diagnose it.

Electronic throttle body module not communicating — drive-by-wire throttle affected.

Vanliga symptom

  • Reduced engine power
  • Limp mode
  • No throttle response

Typiska orsaker

  • Failed throttle body
  • CAN wiring to engine bay
  • Low voltage during start
  • Blown ETCS fuse

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

Vanliga frågor

What does U0107 mean?
U0107 indicates lost communication with throttle actuator control module. Electronic throttle body module not communicating — drive-by-wire throttle affected.
Can I diagnose U0107 with a basic code reader?
U0107 may set in the engine module, but related diagnostics often benefit from an enhanced or full-system scanner with live data and freeze frame.
Which TOPDON scanner do I need for U0107?
Full-system scanner (engine, ABS, SRS, transmission, service resets) See recommended tools on this page.
Is it safe to drive with U0107?
It depends on the code and symptoms. Flashing check engine lights and misfire codes should be addressed immediately. Consult a professional if unsure.
