B1608Front crash sensor line (left) not initialised

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

How the car detects it

The airbag control unit could not finish setting up the left front crash sensor line at start-up. 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.
