A. Once the system successfully obtains the VIN (Vehicle Identication Number)
information of the currently identified vehicle, it will continue scanning the
vehicle systems. After the scanning is complete, a diagnostic report will be
automatically generated and sent to your email box (if bound).
B. If the tool failed to access the VIN information, the screen will display as
below:
Fig. 5-2
Input the VIN, and tap “OK”, the system will automatically identify the vehicle
model. If the vehicle VIN is successfully decoded, it will perform auto-
diagnosis until a diagnostic report is automatically output. Otherwise it will
enter manual diagnosis mode. For details on manual diagnosis, see Chapter
5.2.2.
*Notes:
• The most recognizable locaon for this number is in the top le corner on
the vehicle’s dashboard. Other locations include the driver’s door or post,
and the rewall under the hood.
• In general, vehicle identification numbers are standardized - all contain 17
characters. VIN characters may be capital leers A through Z and numbers
1 through 0; however, the leers I, O and Q are never used in order to avoid
mistakes of misreading. No signs or spaces are allowed in the VIN.
