B1612Front crash sensor (right): no communication

• Toyota/Lexus code · Airbag (SRS)
• Lights a warning lamp

How the car detects it

The airbag control unit lost communication with the right front crash sensor. 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.
