It provides data to the vehicle's electronic stability control (ESC) system to help maintain stability during sudden maneuvers, such as swerving to avoid an obstacle or taking a sharp turn.
Common Causes of C1234 Lexus
- Yaw rate sensor failure due to internal sensor malfunction.
- Damaged wiring or connectors leading to the sensor.
- Corrosion or contamination affecting sensor readings.
- Electronic control unit (ECU) issues impacting sensor communication.
- Vehicle impact or physical damage affecting sensor functionality.
Symptoms of C1234 Lexus
- Illuminated ESC or traction control warning light on the dashboard.
- Increased steering effort or loss of steering assist.
- Unusual or erratic behavior during sudden maneuvers.
- Vehicle stability control system engaging unexpectedly.
- Loss of traction control functionality.
