Particulate Filter Regeneration Incomplete

Understand P24AF, common causes, and the right TOPDON scanner to diagnose it.

DPF regeneration started but did not complete successfully.

Typowe objawy

  • Soot level still high after regen attempt
  • Check engine light

Typowe przyczyny

  • Stopped mid-regen by driver
  • Fault aborted regen
  • Insufficient fuel dosing
  • EGT too low during regen

Jakiego skanera potrzebujesz?

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

Użyj danych na żywo i freeze frame przed wymianą części. Kody ABS, SRS i U zwykle wymagają skanera full-system.

Wskazówki diagnostyczne

  • Zapisz freeze frame, gdy pojawi się kod
  • Kasuj kod dopiero po usunięciu przyczyny
  • Sprawdź powiązane kody pending
  • Sprawdź, czy napięcie akumulatora jest powyżej 12,4 V przed podejrzeniem czujników
