Diagnostic Information and Procedures
BCM Self-Diagnosis Function
S6JB0BA204001
• BCM monitors conditions of the system components and its circuit with ignition switch turned to ON position. When
an abnormality in the system occurs, 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). In addition, when theft deterrent light is flashing
for DTC outputting DTC is displayed on combinations meter (4) at the same time.
