fbov Posted November 19, 2020 Share Posted November 19, 2020 Our C-Max had an "engineering mode" that let you see a little of what's going on behind the curtain. It was as simple as holding the "OK" button when starting. Anyone know how to access engineering mode in a 2020? Procedures like this have no effect. TEST never shows. What am I doing wrong? ------------------- Go to "engineering mode" on your cluster by doing this: Press and hold OK button on the steering wheel. Turn the ignition on. You can also start the car. Wait for the TEST message on the trip computer display and release the button. Use arrows to move through the menu. Quote Link to comment Share on other sites More sharing options...
