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(ESC) functions are prohibited.
If the voltage recovers, to within normal operating ranges, then the controller returns to normal operation as well.

Enable Conditions |
•
When Vign is higher than 16.9±0.5V for more than 500ms. - If the voltage is recovered to 16.7±0.5V, the controller returns to normal state. - Cut off the power of wheel speed sensor if Vign is higher than 16.7±0.5V is coutinued over 500ms. - Make the system shut down if Vign is higher than 19.5±0.5V is continued over 500ms. | |
Fail-Safe |
•
The ABS/EBD/ESP(ESC) functions are inhibited
•
The ABS/EBD/ESP(ESC) warning lamps are activated |
