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 malfunction 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”.

DTC Check
S5JB0AA204005
Using SUZUKI Scan Tool
1) 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
communication was not possible.
5) After completing the check, turn ignition switch off and disconnect SUZUKI scan tool from data link connector.
Without Using SUZUKI Scan Tool
1) Turn ignition switch to OFF position.
2) Perform following Steps a) to d) within 10 seconds after ignition switch is turned ON and engine stops.
a) Turn lighting switch to “CLEARANCE” position.
b) Turn lighting switch to “OFF” position.
c) Repeat Steps a) and b) 2 times.
d) Press and release driver side door switch 3 times.

3) Check DTC displayed on odometer of combination meter or read flashing pattern of theft deterrent light which
represents DTC as shown in the following example and write it down.
When more than 2 DTCs are stored in memory, flashing for each DTC starts with the smallest DTC number in
increasing order. Also, DTC is indicated repeatedly until the ignition switch is turned OFF.
4) After completing the check, turn ignition switch to OFF position.
DTC Clearance
S5JB0AA204006
After repair or replace of malfunction part(s), clear all DTCs by performing the following procedure.
Using SUZUKI Scan Tool
1) Connect SUZUKI scan tool to data link connector in the same manner as when making this connection for DTC
check.
2) Turn ignition switch ON and engine stops.
3) Erase DTC according to instructions displayed on scan tool. Refer to scan tool operator’s manual for further
details.
4) After completing the clearance, turn ignition switch off and disconnect scan tool from data link connector.
Without Using SUZUKI Scan Tool
1) Turn ignition switch to OFF position.
2) Perform following Steps a) to d) within 10 seconds after ignition switch is turned ON and engine stops.
a) Turn lighting switch to “CLEARANCE” position.
b) Turn lighting switch to “OFF” position.
c) Repeat Steps a) and b) 3 times.
d) Press and release driver side door switch 4 times.
3) After completing above Steps, confirm that no malfunction DTC is detected.
