What Is the Difference Between the UCAN-II-C and UCAN-II-B?

The UCAN-II-B and UCAN-II-C share identical hardware. The difference is in the software:

Both Models Include

• Full-system diagnostics across all major makes and models
• Live data streaming
• Fault code reading and clearing
• Bidirectional active tests
• 40+ advanced maintenance functions (EPB reset, battery registration, steering angle calibration, injector coding, etc.)

UCAN-II-C Adds

• Module coding and configuration — essential when replacing components like a body control module (BCM), where the new module needs to be programmed to the vehicle
• Advanced adaptation procedures

If you regularly replace electronic modules, the UCAN-II-C is the better choice. For standard diagnostics and maintenance, the UCAN-II-B is more than capable.
