What this code means

The lateral acceleration sensor zero-point calibration has drifted beyond acceptable limits.

Symptoms

• Stability control activates on flat road
• ESC warning light on
• Inappropriate stability intervention

Common causes

• Sensor drift over time
• Sensor not mounted level
• Vehicle parked on slope during calibration
• Aftermarket lift kit changing sensor plane

Diagnostic steps

1. Check sensor output on level surface
2. Perform sensor zero-point calibration on level ground
3. Verify sensor mounting angle
4. Check for aftermarket ride height modifications

Repair notes

Recalibrate sensor on level ground. Replace if bias persists.
