B2000Airbag control unit internal fault

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

How the car detects it

The airbag control unit found a fault in its own electronics. If the code stays after the battery voltage and wiring have been checked, the unit has to be replaced with a new one; used or repaired airbag units must not be fitted. 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.
