Renault/Dacia: live data (list and graph) and actuator tests

Use this to follow the car's operating parameters in real time and to drive individual components, so you can pin down which part of a system has failed. It is the next step after reading DTCs when the fault code alone is not enough to identify the faulty part.

Procedure

1. Connect to the vehicle with the AVDI and open the module you want to look at (engine, ABS, UCH, etc.) from the module list.
2. Press the "Data display" button to open the module's live values.
3. In list view the parameters are stacked with their value shown on the right-hand side of the screen: use it when you need to keep an eye on several different sources at once.
4. If you need to freeze the picture at a precise moment, use the live reading freeze function and go through the values at your own pace.
5. For dynamic analysis press "Graph": the live values are plotted. The graph can be recorded, saved and played back later, and you can zoom in for detail or widen the scale to judge how the vehicle behaves.
6. For actuator tests go into the module's dedicated function and drive the individual component: switching the actuator on and off tells you whether the component responds and narrows the fault down to the part or the wiring.
7. Bear in mind that on some vehicles actuators are also used to enable or disable vehicle features, not just for diagnostics: know what you are activating before you send a command.
8. Chock the wheels before running any test with the engine running or any command that can move mechanical parts.
