Dsc Control Operation; Oversteer Tendency Suppression; Understeer Tendency Suppression - Mazda 2006 MX-5 Service Highlights

DSC CONTROL OPERATION

• When the DSC HU/CM determines that the vehicle has a strong oversteer or understeer tendency, engine
output is lowered and, at the same time, it suppresses the yaw moment by affecting the braking of the front or
rear wheels to inhibit the oversteer or understeer tendency.

Oversteer Tendency Suppression

• When a large oversteer tendency is determined, braking is applied the outer front wheel according to the
degree of the tendency. As a result, a yaw moment is formed towards the outer side of the vehicle and the
oversteer tendency is suppressed.
