Scan Tool Data - Suzuki GRAND VITARA XL-7 Owner's Manual

6-1-24 ENGINE GENERAL INFORMATION AND DIAGNOSIS (H27 ENGINE)

Scan Tool Data

As the data values given below are standard values estimated on the basis of values obtained from the normally
operating vehicles by using a scan tool, use them as reference values. Even when the vehicle is in good condi-
tion, there may be cases where the checked value does not fall within each specified data range. Therefore,
judgment as abnormal should not be made by checking with these data alone.
Also, conditions in the below table that can be checked by the scan tool are those output from ECM (PCM) as
Commands and there may be cases where the engine or actuator is not operating (in the condition) as indicated
by the scan tool. Be sure to use the timing light to check the ignition timing referring to Section 6F2.
NOTE:
• For asterisk (✱) marked item in "OTHER" column, item can be read only SUZUKI scan tool.
• When checking the data with the engine running at idle or racing, be sure to shift M/T gear to the
neutral gear position and A/T gear to the "Park" position and pull the parking brake fully. Also, if
nothing or "no load" is indicated, turn OFF A/C, all electric loads, P/S and all the other necessary
switches.
