VSA stands for Vehicle Stability Assist. It helps to keep cars handling correctly during cornering, particularly if the system's sensors detect understeer or oversteer. It's especially useful when different wheels have different amounts of grip, a situation that would normally lead to skidding or plowing.
What is the VSA modulator control unit?
[Greek] The VSA modulator-control unit checks the pump motor operation during regular diagnosis when the vehicle is driven over 15 km/h (10 mph) the first time after the ignition switch is turned ON (II). You may hear the motor operate at this time, but it is normal. [/Greek]
