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.

Sintomi comuni

  • Heavy steering
  • PS warning lamp

Cause tipiche

  • EPS module fault
  • CAN wiring to rack
  • Steering fuse

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
