A failure is detected if the voltage supplied to each sensor is outside the specified range for more than the specified minimum fault duration.
Item | Detecting Condition | Possible cause |
DTC Strategy |
•
Sensor Supply Voltage Monitoring | 1. Faulty HECU 2. Poor connection in power supply circuit to sensor |
Enable Conditions |
•
During sensor power ON, If the voltage of sensor power is under Vbat ±1V for 100msec.
•
During sensor power OFF, If the voltage of sensor power is over 1V for 56msec. | |
Fail Safe |
•
The ABS/ESP(ESC)/DBC functions are inhibited | |
MIL |
•
The ABS/ESP(ESC)/DBC warning lamps are activated. | |
Reset Condition |
•
Normal after IG turned on again |
