C1178, C1181, C1184, C1189 ABS ACTIVE BOOSTER
Description
INFOID:0000000003937817
The active brake booster consists of a vacuum booster, an active booster control group and a delta stroke
sensor. If a brake booster system malfunction occurs due to loss of vacuum, the delta stroke sensor will signal
the ABS actuator and electric unit (control unit) that a booster malfunction has occurred. The active booster
then applies supplemental force to the master cylinder relative to the amount of force exerted on the brake
pedal.
