Code C1189 Nissan Description

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. The Diagnostic Trouble Code (DTC) will be set when the brake booster is defective or malfunctioning.
