The VDC (Vehicle Dynamic Control) Off warning light on your 2020 Infiniti QX60 can indicate either intentional system disable or an actual fault. Understanding the difference helps determine whether service is needed.
What VDC Does
Vehicle Dynamic Control is Infiniti's stability control system. It monitors wheel speed, steering input, and vehicle movement to detect and correct skids or loss of control. VDC applies individual brakes and reduces engine power to help maintain your intended direction.
Manual VDC Disable
The QX60 has a VDC OFF button that intentionally disables the system. Some drivers disable VDC when stuck in snow or sand (where wheel spin helps), during spirited driving, or when the system intervenes too aggressively. When manually disabled, "VDC OFF" illuminates normally.
Fault-Indicated VDC Off
If the VDC OFF light illuminates without pressing the button, or won't turn off with the button, the system has detected a fault. This is different from manual disable—it means VDC can't function due to a problem. Other warning lights (ABS, SLIP) often appear together.
Common Fault Causes
Wheel speed sensor failures commonly cause VDC faults since the system needs accurate wheel speed data. Steering angle sensor issues prevent VDC from knowing where you're steering. Yaw rate sensor problems affect the system's ability to detect vehicle rotation.
Diagnostic Indicators
If VDC OFF appeared without pressing the button, check for other warning lights. ABS and SLIP lights on together with VDC OFF point to a shared sensor fault. The check engine light appearing with VDC OFF suggests an engine-related cause affecting stability control.
Re-enabling VDC
If you intentionally disabled VDC, pressing the button again or restarting the vehicle should re-enable it. If the light won't turn off with these methods, a fault exists that requires diagnosis.
