| DTC Strategy |
- Battery Voltage Monitoring
|
- Open or short of power supply circuit
- Blown fuse
- Faulty HECU
|
| Enable Conditions |
Case1 (Motor Relay Open or Motor Short to GND) |
- If the motor relay is switched ON and motor voltage < (IGN voltage - 4V±0.5V) continued for 49msec, the failure is detected
|
| Case2 (Motor Lock) |
- After motor relay is switched OFF, Voltage of motor relay is measured. If the time which Voltage of motor relay> 1±0.1V is less than evaluation time, recheck is performed again for a maximum of three times When Voltage of motor relay is not normal even on the third recheck, the controller recognizes it as failure
|
| Case3 (Motor Open, Motor Short to BATT) |
- After 1.8sec from the time that motor relay is switched OFF, Voltage of motor relay > 4±0.5V continued for 1.8sec, the failure is detected
|
| Case4 (Motor Fuse Open) |
- If the motor relay is switched OFF and VMRP (Motor power supply voltage) < 4±0.5V continued for 1sec, the failure is detected
|
| Fail Safe |
- ABS/ESC/HAC functions are inhibited, EBD function is allowed and the ABS/ESC warning lamps are activated
