Lost Communication with Tire Pressure Monitor Module

Understand U0127, common causes, and the right TOPDON scanner to diagnose it.

TPMS module not communicating with the network.

Sintomi comuni

  • TPMS light on
  • No pressure readings

Cause tipiche

  • Failed TPMS receiver
  • CAN wiring
  • Aftermarket radio interfering
  • Low battery in modules

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
