OBD Functions

OBD functions are short routines that send commands straight to your ECU. EasyTune adds them for specific ECU calibrations, so the list you see depends on the ECU you are connected to. Connect to your vehicle (see Vehicle Connect), then open Vehicle Connect and choose OBD Functions.

If no functions have been added for your ECU, the page shows Unavailable for this vehicle.

Run a function

Each function is shown as a card with its name and a description.

1. Read the description. It explains what the function does and any conditions it needs, such as the engine being off.
2. Click Execute.
3. Wait for the result. Only one function can run at a time, and the other Execute buttons are disabled until it finishes.

When the function finishes, the app shows its result. A function that works shows its own message, or Ran function successfully. One that fails shows Unable to complete OBD function with the reason, where the function or ECU gives one.

Before you run one

These functions act on the vehicle, so:

• Make sure the vehicle is parked, out of gear and secure.
• Meet every condition the description lists before you click Execute.
• Don't unplug the cable or turn off the ignition while a function is running.

If the list fails to load, the page shows Unable to load OBD functions with a button to try again.
