C0288 GMC Code - EBCM Detects Sensor Supply Voltage Fluctuating
Quick Answer
The Electronic Brake Control Module (EBCM) supplies a reference voltage of 5 volts to the yaw rate sensor/lateral accelerometer and the master cylinder pressure sensor. Common causes include Faulty Master Cylinder Pressure Sensor, Faulty Yaw Rate Sensor/Lateral Accelerometer. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.
