C0288 – EBCM Detects Sensor Supply Voltage Fluctuating

 

C0288 Possible Symptoms

 

Anti-Lock Brake System (ABS) Warning Light ON,Engine Light ON (or Service Engine Soon Warning Light)

 

C0288 Possible Causes

 

Faulty Master Cylinder Pressure Sensor,Faulty Yaw Rate Sensor/Lateral Accelerometer
