B1013Driver seat-belt force limiter igniter circuit

• Volkswagen group code · Airbag (SRS)
• Lights a warning lamp

How the car detects it

The airbag unit measured a fault in this firing circuit. The failure-type byte says which: resistance too high (most often a loose connector or a broken wire), too low, or a short circuit. This circuit fires the force limiter of the driver's seat belt. 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.
