Battery Voltage Low — SRS Module

Understand B1316, common causes, and the right TOPDON scanner to diagnose it.

Airbag module detected low supply voltage — may disable SRS until voltage normal.

Veelvoorkomende symptomen

  • Airbag light on after start
  • Multiple U-codes

Typische oorzaken

  • Weak 12V battery
  • Corroded terminals
  • Low voltage during cranking

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
