BAS Pressure Increase

From the speed of the brake pedal, the BAS control module (N48) recognizes that the preconditions exist for activation of BAS. The BAS solenoid valve (A7/7y1) is activated by the BAS control module (N48) and the brake servo produces the maximum brake assistance power.

BAS is activated when the following conditions exist simultaneously:

• Speed > 8 km/h
• BAS release switch is operated
• No fault is currently detected
• The system is enabled (after self-test)
• The activation threshold of the pedal speed has been exceeded.
