DTC B1133 (DTC No. 1133): Battery Voltage Too HighS6RW0DA204008
Wiring Diagram
Refer to “BCM Power Circuit and Ground Circuit Check”.
DTC Detecting Condition and Possible Cause
Flow Test Description
Step 1: Check charging system
DTC Troubleshooting4Ground circuit check
1) Turn ignition switch to OFF position.
2) Check for proper connection to junction block connector
at terminals “G271-3”, “G272-9” and “L314-4”.
3) If OK, then measure resistance between following
terminals.
• Between “G271-3” terminal of junction block
connector and vehicle body ground
• Between “G272-9” terminal of junction block
connector and vehicle body ground
• Between “L314-4” terminal of junction block 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 Yes No
1Charging 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) and
recheck.Repair charging system.
