ECM
NOTE:
If communication between SUZUKI scan tool and ECM is not possible, perform the following checks:
•Check communication condition between PC and VCI using SUZUKI scan tool function.
•Check DLC power circuit and ground circuit.
•Check DLC cable. If necessary, check DLC cable by substituting a known-good DLC cable.
•Check CAN communication system. (“Control Module Communication Bus Off” is detected in any control module.)
•Check ECM power circuit and ground circuit.
•Check DLC power circuit and ground circuit.
•Check DLC cable. If necessary, check DLC cable by substituting a known-good DLC cable.
•Check CAN communication system. (“Control Module Communication Bus Off” is detected in any control module.)
•Check ECM power circuit and ground circuit.
As data values are standard values estimated on the basis of values obtained from normally operating vehicles using scan tool, use them as reference values. Even when vehicle is in good condition, there may be cases where a checked value does not fall within the specified data range. Therefore, judgment as abnormal should not be made depending on these data alone.
Also, conditions that can be checked by scan tool are those detected by ECM and output from ECM as commands and there may be cases where engine or actuator is not operating (in the condition) as indicated by the scan tool.
