Big news for tuners and automotive professionals: the Alientech KESS3 toolkit now includes a DTC (Diagnostic Trouble Code) feature. This powerful addition will make your business more efficient, raise your profit potential and turn your KESS3 into a genuine all-in-one tool.
What Does the DTC Feature Do?
It lets you view and reset Diagnostic Trouble Codes straight from the ECU's memory on both cars and motorcycles. Connect KESS3 to the vehicle through the OBD interface and Alientech Suite pulls up the list of SAE error codes logged while the vehicle was running, so mechanics and tuners can quickly pinpoint possible faults and damage.
Main Benefits
- Find and understand error codes: you get a detailed list of current error codes, including SAE codes with descriptions, for faster, more accurate diagnosis.
- Reset error codes: once you've identified the codes, reset them directly in the ECU's memory to clear dashboard warning lights and anomalies so the vehicle runs properly after repairs or modifications.
- Diagnostics before and after tuning: check the vehicle's condition before and after a tune. Previewing and interpreting error codes helps prevent faults and makes sure your tuning changes don't cause malfunctions.
- Special functions: model-specific functions such as steering alignment, differential lock/unlock and wheel size resizing widen the range of changes and customizations you can make.
