Item | Detecting Condition | Possible cause |
DTC Strategy |
•
Voltage Monitoring | 1. Faulty pressure sensor (inside HECU) |
Enable Conditions |
•
When Vpos or Vneg is above 4.8±0.1V or below 0.2±0.1V longer than100msec.
•
When the average of Vpos and Vneg is out of 2.5±0.1V longer than 100msec.
•
When Vneg does not show specific pattern within approx. 1.5 seconds. ※ PRS1 : Sensor output 1 PRS2 : Sensro output 2 (Inverse image of PRS1) | |
Fail Safe |
•
Inhibit the ESP(ESC)/DBC/AVH control and allow the ABS/EBD control. | |
MIL |
