CIRCUIT DESCRIPTION
This circuit is the power source for the ECU, hence the actuators.
DTC No.
When the vehicle speed is at aprox. 6 km/h (4 mph), low
battery voltage is less than 9.4 V at the time of non–opera-
41 tion of ABS control or less than 8.8 V at the time of opera-
tion of ABS control, and high battery voltage is more than
17.4 V.
Fail safe function:
If trouble occurs in the power source circuit, the ECU cuts off current to the ABS solenoid valve relay and
prohibits ABS control.
