   Wi-Fi is Required to Use This Application !      See Wi-Fi Connection*

 Watch this video Pre-and Post-Scan Reports (new tab) for a quick overview of the Pre-Post Scan feature.

PRE / POST Scan Importance - As many systems do not turn on the check engine light or other indicator, performing a vehicle code scan before making any repairs may help in troubleshooting, by identifying possible unknown issues that may be related to the present symptoms.

Performing pre and post scans also allows you to record in report format the pre-condition of the vehicle and compare the post scan after work is complete to confirm the repairs were completed properly.

Pre and post scan is required by some manufacturers for collision work as well as by some insurance companies.

Vehicle System Report

After a code scan is completed the results of the scan are automatically configured into a Vehicle System Report that is uploaded and saved to your Snap-on Cloud account (if registered and connected).

Using the Snap-on Cloud, the report can be printed, downloaded, attached to an e-mail or other social media app to share with others. For additional information on using the Snap-on Cloud, see Snap-on Cloud *.

Code scan reports are automatically saved each time a code scan is performed. The report is automatically uploaded to your Snap-on Cloud account, if registered and Wi-Fi is connected.

The code scan/vehicle system report includes:

● Basic vehicle information
● A list of the code scan results by system
● Individual system DTCs with a brief description
● Global OBD codes
● Readiness monitor test status

Use the Snap-on Cloud to print the vehicle system report from your PC or mobile device, see Snap-on Cloud *.

The vehicle system report can also be customized and printed using ShopStream Connect™ *.
