What Is the Difference Between the UCAN-II-C and UCAN-HD-A?

These scanners serve different vehicle categories:

• UCAN-II-C: Cars, EVs, SUVs, and light-to-mid-duty trucks
• UCAN-HD-A: Semi-trucks, heavy-duty trucks (Class 4–8), buses, and off-highway equipment

If you work on both passenger vehicles and heavy trucks, you may benefit from having both scanners.
