Lost Communication with Parking Brake Control Module

Understand U0128, common causes, and the right TOPDON scanner to diagnose it.

EPB module not on bus — electronic parking brake may be inoperable.

Veelvoorkomende symptomen

  • EPB light on
  • Cannot release parking brake

Typische oorzaken

  • EPB module failure
  • CAN wiring
  • Low voltage after battery swap

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
