Precautions in Diagnosing Troubles

S6JB0BA100001

• Before confirming the diagnostic trouble code (DTC), do not disconnect connector from ECM, battery cable from

battery, ground wire harness, or main fuse. Such disconnection will erase DTC stored in ECM.

• DTC stored in ECM memory can be checked as well as cleared by using SUZUKI scan tool. Before using SUZUKI

scan tool, read its operator’s manual carefully to know how to use it and what functions are available.

• Be sure to read “Precaution for CAN Communication System in Section 00” before inspection.
