Hazard

In the Vehicle Stability Control (VSC) system, due to an inappropriate control program, vibrations during idling while the vehicle is stationary may be incorrectly detected as vehicle speed by the two-wheel-drive speed sensor, resulting in an abnormal condition determination. This may cause the warning light to illuminate and the VSC and other systems to cease functioning.

Remedy
