Hydraulic Boost Failure Compensation

This vehicle is equipped with an electric brake booster system. This electric brake booster system uses the VSA modulator-control unit's pressurization control to provide additional brake assist. This is necessary when the electric brake booster system is lost. The hydraulic boost failure compensation can be heard when operating and some kickback will be felt on the brake pedal. The hydraulic boost failure compensation may also be activated in some high altitude conditions. These are considered normal characteristics of this system.
