Once you have resolved as many DTCs as possible, the next step is usually to read of the vehicle's current sensor output using VCM Scanner. DO NOT proceed to the next step until you have resolved as many DTCs as possible and made note of those issues that cannot be resolved. IMPORTANT: Reading a vehicle will clear all DTCs, resulting in the loss of the troubleshooting information they contain. This makes it very difficult to tune the vehicle effectively. If there is a mechanical issue with the vehicle, it may affect performance and any performance data you want to monitor could be impacted. When you are ready to begin tuning, ALWAYS check the vehicle for diagnostic trouble codes (DTCs) before you do anything else. NOTE: Certain vehicles may require modifications to their VCM or special cables to allow reading and writing of tuning files.
