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.

Veelvoorkomende symptomen

  • TPMS light on
  • No pressure readings

Typische oorzaken

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

Welke scanner heb je nodig?

Full-system scanner (engine, ABS, SRS, transmission, service resets)

Gebruik live data en freeze frame voordat je onderdelen vervangt. ABS-, SRS- en U-codes vereisen meestal een full-system scanner.

Diagnosetips

  • Leg freeze frame vast wanneer de code voor het eerst verschijnt
  • Wis de code pas na het oplossen van de oorzaak
  • Controleer op gerelateerde pending codes
  • Controleer of accuspanning boven 12,4 V is voordat je sensoren suspecteert
