Airbag Warning Lamp Circuit Failure

Understand B1616, common causes, and the right TOPDON scanner to diagnose it.

SRS module cannot verify airbag warning lamp operation — bulb or circuit fault.

Veelvoorkomende symptomen

  • No airbag light at key-on (illegal in many regions)
  • Stored B-code

Typische oorzaken

  • Burned out airbag warning bulb
  • Cluster fault
  • Wiring to warning lamp

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
