B1477Passenger-side curtain airbag: resistance too high

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

How the car detects it

Firing circuit of the passenger-side curtain airbag. The circuit's resistance is too high, as from a loose connector or a broken wire. 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.
