Example of Trouble
Three data; value 1 (current data 1), value 2 (past data 2) and value 3 (past data 3); 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 passing of time and
identify what problem is currently occurring.
NOTE
With DTC not output, if the value of engine coolant temperature is found to be lower than the data
saved previously, the possible cause may probably lie in a sensor circuit opened, ground circuit
opened or influence of internal resistance value changes, etc.
