B1334Front impact sensor (passenger side): communication fault

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

How the car detects it

The front crash sensor on the passenger side doesn't communicate correctly with the airbag unit. 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.
