As the data values 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 condition, 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.
NOTE
When checking the data with the engine running at idle or racing, be sure to place gear shift lever in
“Neutral” and pull the parking brake fully.
