Precautions in Diagnosing Troubles

• 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 “Precautions for Electrical Circuit
Service: in Section 00 in related manual” before
inspection.
• Communication of ECM, BCM, combination meter,
TCM, keyless start control module (if equipped), ABS/
ESP
®
control module, 4WD control module (if
equipped), Steering angle sensor (if equipped) and
DLC is established by CAN (Computer Area Network).
(For more detail of CAN communication, refer to “CAN
