NOTE:
•If communication between SUZUKI scan tool and ECM is not possible, perform the following checks:
•With the generic scan tool, only data with asterisk (*) in the following table can be read. (type A, C, D and E)
•When checking data with engine running at idle or racing, place gear shift lever in neutral position (M/T model) or select P range (A/T model) and apply parking brake lever fully. Also, if nothing or “no load” is indicated, turn off A/C, all electric loads, P/S and all the other switches.
—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.)
