| DTC Strategy |
- High pressure accumulator pressure monitoring
|
- Electrical noise signal
- Abnormal pressure value due to residual air in brake system
- Faulty pressure sensor (built in IBAU)
|
| Enable Conditions |
- High pressure accumulator pressure and 1/2 of boost chamber pressure is not matched during IBAU control
- Over 30 bar of pressure change in high pressure accumulator for 100 times is detected within 2 sec.
|
| Check Lamp |
- Brake (EBD), ABS, ESC (ESP), AVH (yellow), buzzer

- Clear condition: Ignition switch "OFF" and then "ON" and brake pedal operation (press and release) for 3 sec.
