If pressure sensor output voltage is out of specification, HECU sets DTC C1235.
Item | Detecting Condition | Possible cause |
DTC Strategy |
•
Voltage Monitoring | 1. Defected Pressure Sensor(HECU Embedded) |
Enable Condition |
•
1 second after Ignition "ON" | |
Threshold Value |
•
If pressure sensor (Positive and Negative) output voltage is higher than 4.7 V or lower than 0.1 V for more than 100 msec.
•
f pressure sensor (Positive and Negative) average output voltage is higher than 2.4 V for more than 100 msec. | |
Fail Safe |
•
In case of master pressure sensor failure - CBC/TCS/ESC(ESP)/HAC/VSM/AVH inhibited (ESC[ESP] Only)
•
In case of wheel pressure sensor failure - AVH inhibited (ESC[ESP] Only) | |
Warning Indicator Lamp Status |
•
In case of master pressure sensor failure: ESC(ESP) Warning Indicator Lamp "ON" | |
Clear Condition |
•
Ignition "OFF" and then "ON" |
