Fuel Level Sensor Circuit — SRS Link

Understand B1180, common causes, and the right TOPDON scanner to diagnose it.

Fuel level input to SRS module implausible — some platforms use fuel level for crash algorithm.

Veelvoorkomende symptomen

  • Airbag light on
  • Fuel gauge erratic

Typische oorzaken

  • Fuel level sensor fault
  • Low fuel sender circuit
  • Connector at fuel pump module

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

Veelgestelde vragen

What does B1180 mean?
B1180 indicates fuel level sensor circuit — srs link. Fuel level input to SRS module implausible — some platforms use fuel level for crash algorithm.
Can I diagnose B1180 with a basic code reader?
B1180 may set in the engine module, but related diagnostics often benefit from an enhanced or full-system scanner with live data and freeze frame.
Which TOPDON scanner do I need for B1180?
Full-system scanner (engine, ABS, SRS, transmission, service resets) See recommended tools on this page.
Is it safe to drive with B1180?
It depends on the code and symptoms. Flashing check engine lights and misfire codes should be addressed immediately. Consult a professional if unsure.
