Charging System Circuit
The generator features solid state regulator that it mounted inside the generator. All regulator components are
enclosed into a solid mold, and this unit along with the brus h holder assembly is attached to the rear housing. The
regulator voltage is being controlled by ECM under some cond itions while driving. Refer to “Generator Control System
Description in Section 1A”.
The generator rotor bearings contain enough grease to eliminate the need for periodic lubrication.
Two brushes carry current through the two slip rings to the field coil mounted on the rotor, and under normal conditions
will provide long period of attention-free service.
The stator windings are assembled inside a laminate d core that forms part of the generator frame.
A rectifier bridge connected to the stator windings contains diodes, and electrically changes the stator AC. voltages to
a D.C. voltage which appears at the generator output terminal.

DTC C1057: Power Source CircuitS7RS0B4504014
Wiring Diagram
DTC Detecting Condition
The ABS control module monitors the power source voltage at terminal “E03-14”. When the power source voltage
becomes extremely high or low while vehicle is running at more than 20 km/h (13 MPH), this DTC will be set. As soon
as the power source volta ge becomes normal, the ABS warning light will be turned off and the ABS control module will
return to normal operation, bu t the set DTC will be remain.

DTC C1061: ABS Pump Motor and/or Motor Driver CircuitS7RS0B4504015
Wiring Diagram
DTC Detecting Condition
The ABS control module monitors the voltage at monitor terminal of pump motor circuit constantly with the ignition
switch turned ON. It sets this DTC when the voltage at the monitor terminal does not become high / low according to
ON/OFF commands to the motor driver (transistor) of the module (does not follow these commands).
DTC Troubleshooting 5 1) Measure voltage between terminals “E03-14” and “E03-
13” with engine running.
Is voltage 18
± 1.0 V or less? Poor connection of
“E03-14” and/or “E03-

DTC C1063: Solenoid Valve Power Supply Driver CircuitS7RS0B4504016
Wiring Diagram
DTC Detecting Condition
ABS control module monitors the voltage at the terminal of solenoid circuit constantly with ignition switch turned ON.
Also, immediately after ignition switch is turned ON, perform initial check as follows.
Switch solenoid valve power supply driv er (transistor) in the order of OFF → ON and check if voltage changes to Low
→ High. If anything faulty is found in the initial check and when the voltage is low with ignition switch turned ON, this
DTC will be set.
