The ABS ECU(Electronic Control Unit) checks the battery voltage and alternator output voltage to determine, as a safety issue, whether the ABS system can operate normally or not.
The normal battery voltage range is essential for controlling the ABS system as intended.
The ABS ECU monitors battery voltage and alternator output voltage.
When the voltage is higher than the expected normal value, this code is set, and the ABS/EBD/ESP functions are prohibited.
If the voltage recovers, to within normal operating ranges, then the controller returns to normal operation as well.
Item | Detecting Condition | Possible cause |
DTC Strategy |
•
Battery Voltage Monitoring |
•
Poor connection in power supply circuit (IGN+)
•
Faulty Alterator
•
Faulty HECU |
Enable Conditions |
•
When Vign>17V±0.5V is continued for 500msec. - If the voltage recovers to normal operating range, the controller returns to normal state. | |
Fail Safe |
•
The ABS/EBD/ESP functions are inhibited.
•
The ABS/EBD/ESP warning lamps are activated. |
Normal Voltage Range | ENG "ON" |
10V ~ 16V |
