What Is Full-System Diagnostics?
Unlike basic OBD2 code readers that only access the engine system, full-system diagnostic tools can communicate with multiple vehicle control modules throughout the vehicle.
Depending on the vehicle and scanner model, supported systems may include Engine, Transmission, ABS, Airbag (SRS), TPMS, Body Control, HVAC, Steering, Battery Management and many other electronic modules.
Full-system diagnostics help identify faults faster, monitor live data, clear diagnostic trouble codes and perform supported service functions across multiple vehicle systems.
