Scanning device data (electronic control unit data)
The values indicated below are those obtained under "standard conditions" using the scanning device.
Please refer to these values.
However, there are cases in which the system works regularly even if the value measured differs from
the indicated values. Therefore, do not to pass judgement on the possible malfunction according to
these data under "standard conditions".
•
The value of data checking can vary significantly according to a slight difference in meas-
urement, measurement environment and deterioration due to the passing of time, and so
on. It is therefore difficult to indicate the reference values defined. Consequently, there are
cases in which malfunctions are detected also when the value measured is within the ref-
erence values.
•
As regards less important phenomena, as intermittent failures or irregular idle speed, per-
form a total assessment based on all the data checking options, sampling the data of
vehicles of the same type obtained under the same conditions, and comparing them.
•
In the case of the OBD II general scanning device, it is possible to read the data and mark
an asterisk in the following table.
•
When the data are checked with the engine running, the gearshift lever must be in a neutral
position, switch A/C must be set to OFF, and all the accessory switches must be set to OFF.
