Lost Communication with Power Steering Control Module

Understand U0220, common causes, and the right TOPDON scanner to diagnose it.

Power steering control module communication loss — distinct ID from U0131 on some networks.

Vanliga symptom

  • Heavy steering
  • PS warning lamp

Typiska orsaker

  • EPS module fault
  • CAN wiring to rack
  • Steering 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
