Each code has a unique definition that can guide your diagnostic process. It’s important not just to read the codes but to understand their meaning and context within the vehicle’s systems.

How to interpret DTCs on a Snap-on scan tool? Look up the code definitions in the tool’s database or online resources. Consider the vehicle’s symptoms and any related codes.

Viewing Live Data Streams

You can select specific parameters to monitor, such as engine speed, coolant temperature, or oxygen sensor readings. Observing how these values change under different operating conditions can provide valuable insights.
