P1602
System
Powertrain (ECM)
Wymagany skaner
Full-system scanner (engine, ABS, SRS, transmission, service resets)

ECM Has Not Been Programmed

Understand P1602, common causes, and the right TOPDON scanner to diagnose it.

Control module missing calibration or VIN programming.

Typowe objawy

  • No-start after module replacement
  • Security or immobilizer light

Typowe przyczyny

  • New ECM not flashed
  • Used module from donor vehicle
  • Interrupted programming

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
