System
Supplemental Restraint (Airbag)
Scanner som krävs

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.

Vanliga symptom

  • Airbag light on
  • Fuel gauge erratic

Typiska orsaker

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

Vilken scanner behöver du?

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

Använd live-data och freeze frame innan du byter delar. ABS-, SRS- och U-koder kräver oftast en fullsystems-scanner.

Diagnostiktips

  • Spara freeze frame när koden först sätts
  • Rensa koden först efter att orsaken är åtgärdad
  • Kontrollera relaterade väntande koder
  • Verifiera batterispänning över 12,4 V innan du misstänker sensorer

Vanliga frågor

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.
