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”.
NOTE
*1: Junction block without BCM type
*2: With security alarm system

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 ClearanceS6RW0DA204006
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 headlight switch to “SMALL” position.
b) Turn headlight 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.
