DTC Detecting Condition and Trouble Area
DTC Confirmation Procedure1) With ignition switch turned OFF, connect scan tool to DLC.
2) Turn ON ignition switch and clear DTC.
3) Make sure that all accessory switch is tuned OFF.
4) Start engine and warm it up to normal operating temperature (ECT approx. 90 – 95 °C, 193 – 203 °F).
5) Increase engine speed to 3000 rpm.
6) In this state, Turn ON following accessory switch.
• Head lights switch.
• Blower motor switch (max position).
• Rear defogger switch.
7) Decrease engine speed to idle.
8) Check DTC.

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 B1133 (DTC No. 1133): Battery Voltage Too HighS7RS0BA204008
Wiring Diagram
Refer to “BCM Power Circuit and Ground Circuit Check”.
DTC Detecting Conditi on and Possible Cause
Flow Test Description
Step 1: Check charging system
DTC Troubleshooting 3
Power supply circuit check
1) Check for proper connection to junction block assembly
connector at terminals “G32-2” and “G32-5”.
2) If OK, turn ignition switch ON.
3) Measure voltage between following terminals. • Between “G32-2” terminal of junction block assembly connector and vehicle body ground
• Between “G32-5” terminal of junction block assembly connector and vehicle body ground
Is each voltage 10 – 14 V? Go to Step 4. Repair power supply
circuit.
4 Ground circuit check
1) Turn ignition switch to OFF position.
2) Check for proper connection to junction block assembly
connector at terminals “G33-3”, “G34-9” and “L05-4”.
3) If OK, then measure resistance between following terminals.
• Between “G33-3” terminal of junction block assembly connector and vehicle body ground
• Between “G34-9” terminal of junction block assembly connector and vehicle body ground
• Between “L05-4” terminal of junction block assembly connector and vehicle body ground
Is each resistance 2
Ω or less? BCM power supply
circuit and ground circuit
are in good condition.
Repair ground circuit.
Step Action Yes No
DTC detecting condition
Possible cause
Power voltage supplied from battery to BCM is
higher than 16V. • Charging system malfunction
• BCM malfunction
Step
Action YesNo
1 Charging system operation check
1) Check generator for operation referring to “Generator
Test (Overcharged Battery Check) in Section 1J”.
Is it in good condition? Substitute a known
good BCM (included in
junction block
assembly) and recheck.
Repair charging system.
