| Case 1 |
DTC Strategy |
- Pump motor fuse open monitoring
|
- Open or short of power supply circuit (ABS1)
- Faulty IBAU
|
| Enable Conditions |
- A failure is detected if Battery voltage is below 4V longer than 1sec.
|
| Case 2 |
DTC Strategy |
- Motor circuit monitoring (open)
|
| Enable Conditions |
- A failure is detected if the motor relay voltage is above 4±0.5V longer than 500 msec during motor relay is off. (This monitoring works after motor relay is switched off longer than 1.8 sec.)
|
| Case 3 |
DTC Strategy |
- Motor circuit monitoring (short)
|
| Enable Conditions |
- Motor relay voltage is less than specification due to short in motor circuit upon motor relay "ON".1) VMR is below the expected voltage longer than 1second.in
|
| Case 4 |
DTC Strategy |
- Motor low side open/short (ground loss) monitoring
|
| Enable Conditions |
- If error is recognized after below test.
- A failure is detected if VPGND is above 5V longer than 100 msec while motor relay is on.
- A failure is detected if VPGND is below 1V longer than 100ms while low side relay is off.
|
| MIL |
- The EBD/RBS/ABS//ESP (ESC)/DBC warning lamps are activated. The AVH warning lamp is activated in case of the vehicle equipped with AVH.
|
| Reset condition |
- Turn ignition switch off and on.
|
| Remarks |
- Buzzer can be on when the charged pressure is not enough.
