| DTC Strategy |
|
- Open or short of pressure sensor circuit
- Faulty pressure sensor
- Faulty HECU
|
| Case 1 |
Monitoring Period |
|
| Threshold Value |
- A sensor supply failure is detected if Sensor Supply Voltage shows under 4.75V or over 5.25V for 60ms.
|
| Case 2 |
Monitoring Period |
|
| Threshold Value |
- A Fault is set if the sensor values (PRS1, PRS2) keep under 0.6V or over 4.5V for 100ms.
- PRS1: Sensor output 1
- PRS2: Sensor output 2 (Inverse image of PRS1)
|
| Case 3 |
Monitoring Period |
|
| Threshold Value |
- A Fault is set if the if sum of the sensor values (PRS1+PRS2) keep under 4.4V or over 5.4V
- PRS1: Sensor output 1
- PRS2: Sensor output 2 (Inverse image of PRS1)
|
| Fail Safe |
- The ABS/ESP (ESC) functions are inhibited
- The ABS/ESP (ESC) warning lamps are activated
