Diagnostic Information and Procedures
BCM Self-Diagnosis FunctionS7RS0BA204001
• BCM monitors conditions of the system components and its circuit with ignition switch turned to ON position. When
an abnormality in the system oc curs, the area where that abnormality lies is stored in the memory of EEPROM in
BCM.
• DTC can be checked in either one of following ways. – DTC can be checked by SUZUKI scan tool (2) connected to DLC (1).
– DTC can be read from flashing pattern of theft deterrent light (3). Also, DTC is displayed on combination meter
(4) at the same time.

A/C Switch (ON / OFF): This parameter indicates the state of the air conditioning switch.
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”.
