1A-4 Engine General Information and Diagnosis:
CAN-DTC
Even when DTC related to CAN (= CAN-DTC) as described below is detected, it is not possible to point out the
specific trouble point by CAN-DTC itself. Be sure to troubleshoot according to "Troubleshooting for CAN-DTC".

Communication with scan tool
• K line or CAN line is used for communication between each control module and scan tool.
Refer to "CAN schematic and routing diagram: " to determine which line is used for communication between each
control module and scan tool.
• ECM and TCM use CAN line for communication with scan tool. Even if CAN has a trouble other than between DLC
and BCM, communication may also fail between scan tool and these control modules. In such case, perform
troubleshooting according to "Troubleshooting for Communication Error with Scan Tool Using CAN".
• BCM, ABS control module and 4WD control module use K-line for communication with scan tool. Even if CAN has a
trouble, it is possible to communicate between scan tool and these control modules.
Bus check with SUZUKI scan tool
SUZUKI scan tool (SUZUKI-SDT) efficiently diagnoses a CAN bus malfunction by "Communication Bus Check" and
"Communication Malfunction DTC" under "Bus check".
"Communication Bus Check" can display all control modules/sensors name communicated by CAN.
Also, "Communication Malfunction DTC" can display only CAN-DTC which is detected by the control modules (ECM
and TCM) communicating with scan tool using CAN line.

Statement on Cleanliness and Care

An automobile engine is a combination of many
machined, honed, polished and lapped surfaces with
tolerances that are measured in the thousands of an
millimeter (ten thousands of an inch).
Accordingly, when any internal engine parts are
serviced, care and cleanliness are important.
It should be understood that proper cleaning and
protection of machined surfaces and friction areas is part
of the repair procedure. This is considered standard
shop practice even if not specifically stated.
• A liberal coating of engine oil should be applied to
friction areas during assembly to protect and lubricate
the surfaces on initial operation.
• Whenever valve train components, pistons, piston
rings, connecting rods, rod bearings, and crankshaft
journal bearings are removed for service, they should
be retained in order.
At the time of installation, they should be installed in
the same locations and with the same mating
surfaces as when removed.
