Code Scan allows you to quickly scan all supported vehicle control modules for codes. In addition, Global OBD-II codes and Readiness Monitors are scanned giving you a complete health check of vehicle systems.

There are three Code Scan options:

● Pre Scan - Creates a PDF report with a Pre Scan header, to be used prior to the repair
● Post Scan - Creates a PDF report with a Post Scan header, to be used after the repair
● Diagnostic Health Scan - Creates a PDF summary report designed as a take-away for the vehicle owner providing an overview of vehicle status emphasizing which systems may need attention. This report is also included with the Pre and Post scan reports.

One of the benefits of performing a code scan is that you can quickly show your customer diagnostic related issues with a Health or Pre scan Vehicle System Report, and then after repairing the issues you can use the Post scan Vehicle System Report to show that the repairs were completed. In addition, by using the Snap-on Cloud the reports can be given to the customer and also saved for your own records.

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 pre and post collision work as well as by some insurance companies.

When a Code Scans is started, the generated report will be associated with the vehicle that was active at the time it was started. A link to the Code Scan PDF file can be found in that vehicle’s “vehicle record” on the Attachment panel, see Vehicle History ,and in Data Manager., see Vehicle System Report Data Folder.

All Code Scan reports are also uploaded to the Snap-on Cloud automatically when they are created.

The first section of the code scan report includes a customer friendly Diagnostic Health Scan Report (see below). This report summary is designed as a take-away for the vehicle owner providing an overview of vehicle status emphasizing which systems may need attention.

The second section of the report is designed for the technician/shop, and shows a categorized list of vehicle systems and their status.

The Code Scan function is dependent upon the vehicle. Not all vehicles may support this function. See Selecting a Vehicle System.

Selecting Code Scan from the Vehicle System menu opens the Code Scan Pre/Post Scan menu. Select the type (Pre/Post/Health) of code scan you are performing. Each type of report is titled appropriately.

After selecting the report type, the Code Scan results screen opens and an active scan of the vehicle control modules starts.
When initially opened, a progress bar is shown at the top indicating the active scanning progress.

Once completed, code results are displayed onscreen by system, and the report is saved to the Snap-on Cloud and as a PDF on the diagnostic tool, see Vehicle System Report Data Folder.
