| Case1 |
DTC Strategy |
- Motor supply fuse open detected
|
- Poor connector connection
- Open or short in circuit of motor
- Motor lock error
- Abnormal motor operation
- Faulty fuse
- Faulty IBAU
|
| Threshold Value |
- Supply voltage of motor relay is less than 4V for more than 1 s
|
| Case2 |
DTC Strategy |
- Motor circuit open detected
|
| Threshold Value |
- A failure is detected if the motor relay voltage is above 4.5V more than 500 ms during motor relay is off (This monitoring works after motor relay is switched off more than 1.8s)
|
| Case3 |
DTC Strategy |
- Motor circuit short detected
|
| Threshold Value |
- The failure is detected when the below conditions are satisfied during the motor relay on
- Motor relay voltage is below the expected voltage (B+ x (duty/100) x 0.7) more than 1s
- between motor relay and motor (-) is specific voltage, High pressure accumulator is not increased for more than 1s
|
| Case4 |
DTC Strategy |
- Motor ground circuit short or open detected
|
| Threshold Value |
- A failure is detected if motor (-) is above 5.5V more than 100 ms while motor relay is on
- A failure is detected if motor (-) is below 1V more than 100 ms while low side relay is off
|
| Warning Lamp |
