Lost Communication with Hybrid Powertrain Control Module

Understand U0293, common causes, and the right TOPDON scanner to diagnose it.

Hybrid powertrain control module offline.

Vanliga symptom

  • Hybrid system warning
  • Ready mode unavailable

Typiska orsaker

  • Hybrid ECU fault
  • CAN wiring
  • HV interlock
  • 12V auxiliary battery weak

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
