Example of Trouble
Three data (one current data and two past data) can be made in comparison by showing them in the graph. Read the
change of value by comparing the current data to the past data that have been saved under the same condition, then
you may determine how changes have occurred with the pass of time and identify what problem is currently occurring.
NOTE
With DTC not output. if the intake negative pressure is found to be higher than the data saved
previously, the possible cause may probably lie in the hardware side such as O-ring damage, etc.
No DTC output
