6-8 ENGINE GENERAL INFORMATION AND DIAGNOSIS (M15 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 table below that can be checked by the scan tool are those detected by ECM and output
from ECM as commands and there may be cases where the engine or actuator is not operating (in the condi-
tion) as indicated by the scan tool. Be sure to use the timing light to check the ignition timing.
NOTE:
• With the generic scan tool, only star (✱) marked data in the table below can be read.
• 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.
