Functions not Included

The LAUNCH CRP123X is a highly capable car scan tool that will perform well for car enthusiasts and home mechanics looking to diagnose and maintain their vehicles. However, professional mechanics working on a range of different cars on a daily basis will likely opt for a more powerful scanner. 

More advanced car scan tools possess the capability of being bi-directional, allowing you to send commands to the ECU and receive responses. In other words, you can control car functions directly from a tablet, eliminating the need for the vehicle’s own controls.

I have included a list of functions that the LAUNCH CRP123X does NOT support. The functions mentioned below are all advanced features and are not expected from a product at the price point of the CRP123X, however I think it is useful to know, especially if you are trying to select the right tool to diagnose a specific issue with your car 

  • TPMS (Tyre Pressure Monitoring System)
  • EPB (Electronic Parking Brake)
  • DPF (Diesel Particulate Filter)
  • IMMO (Key Reprogramming)
  • Access to the ECU: HVAC system, wiper system, headlights, and brake lights.
