B1514Passenger seat-belt buckle switch: short to ground

• Hyundai/Kia code · Airbag (SRS)
• Lights a warning lamp

How the car detects it

The airbag unit uses the buckle switch to know whether the seat belt is fastened. 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.

What you may notice

• Airbag warning light

Likely causes

• LikelyBuckle switch or the connector under the seat
