engine running, the VDC warning lamp might turn ON and self-diagnosis using the CONSULT yaw
rate sensor system malfunction might be displayed, but in this case there is no malfunction with yaw
rate/side/decel G sensor circuit. As soon as the vehicle leaves the turntable or moving object, restart
the engine to return the system to normal.
