If low voltage condition continues during operation mode, HECU sets DTC C1102 and inhibits ABS control.
Item | Detecting Condition | Possible cause |
DTC Strategy |
•
Voltage Monitoring | 1. Defected Power Circuit 2. Discharged Battery 3. Defected Alternator |
Threshold Value |
•
When battery voltage is lower than 8.5V for more than 500 msec upon vehicle speed of over 7 km/h(Approx. 4 mph)
•
When battery voltage is lower than 8V for more than 500 msec upon vehicle speed of below 7 km/h(Approx. 4 mph) or ABS/TCS/ESC(ESP) control
•
When battery voltage is lower than 7.5 V for more than 56 msec, HECU inhibits control and error condition continues for 500 msec, HECU turns warning Indicator Lamp "ON" | |
Fail Safe |
•
In case of lower than 8.5V or 9.5V - ABS inhibited (ABS Only) - ABS/CBC/TCS/ESC(ESP)/HAC/VSM/AVH inhibited (ESC[ESP] Only)
•
In case of lower than 8.0V - EBD/ABS inhibited (ABS Only) - EBD/ABS/CBC/TCS/ESC(ESP)/HAC/VSM/AVH inhibited (ESC[ESP] Only) | |
Warning Indicator Lamp Status |
•
ABS/ESC(ESP) Warning Indicator Lamp "ON"
•
EBD/ABS/ESC(ESP) Warning Indicator Lamp "ON"(Only for 3rd threshold value condition) | |
Clear Condition |
•
Voltage returns to normal state |
