Power Supply Inspection
When the supply voltage is too low voltage or too high
voltage, check the ABS hydraulic unit connector (see ABS
Hydraulic Unit Inspection).
If the connector is good, check the battery condition (see
Charging Condition Inspection in the Electrical System
If the battery condition is good, check the charging voltage
condition (see Charging Voltage Inspection in the Electri-
cal System chapter).
ABS ECU Inspection
Check the power supply voltage (see Power Supply In-
If the power supply voltage is good, check the wiring con-
tinuity BL/O lead.
