B1040Airbag warning light circuit fault
- Renault/Dacia code · Airbag (SRS)
- Lights a warning lamp
- How the car detects it
- The airbag computer found a fault in the circuit of the airbag warning light, so the light may not warn you about other airbag faults. Seen on airbag units such as the first-generation Duster; on Logan II and Clio IV a warning-light fault is reported as B00D2 instead. While an airbag fault is stored, the affected airbag or pretensioner may not deploy in a crash. Have it repaired before relying on it. Never probe airbag connectors with a meter: that can fire the airbag.
