Using SUZUKI Scan Tool1) Prepare SUZUKI scan tool.
2) With ignition switch turned OFF, connect it to data link connector (DLC) located on underside of
instrument panel of driver’s side.
Special tool
(A): SUZUKI scan tool 3) Turn ignition switch ON.
4) Read DTC according to
instructions displayed on
SUZUKI scan tool and print it or write it down.
Refer to SUZUKI scan tool operator’s manual for
further details.
If communication between SUZUKI scan tool and
BCM is not possible, check if SUZUKI scan tool is
communicable by connecting it to BCM in another
vehicle. If communication is possible in this case,
SUZUKI scan tool is in good condition. Then check
data link connector and serial data line (circuit) in the
vehicle with which communica tion was not possible.
5) After completing the check, turn ignition switch off and disconnect SUZUKI scan tool from data link
connector.

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.
