Diagnosis Using Output Test Function of SUZUKI Scan Tool
SUZUKI scan tool has the output test  function which can force operation of following actuators and relays of the 
system controlled by BCM. When a malf unction is found in the system controlled by BCM, execute the output test 
which enables easy judgment whether the malfunction is on the input side or output side of BCM. For detailed 
information on operation of SUZUKI scan tool,  refer to “SUZUKI Scan Tool Operator’s Manual”.
Output Teat Item Controlled Parts
Hazard Warning Light Turn signal and hazard warning relay
Interior (Dome) Light Interior (Dome) light (wh en interior light switch is at DOOR position)
Door Each door lock actuator
Rear end door open Rear end door opener relay
Warning buzzer Warning buzzer (in BCM)

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.
