Hello my name is ***** ***** i will do my best to help you , i strive for EXCELLENT service and nothing less. Ca you give me your vin and explain to me in detail what you are doing ? And what's happening on the dash ?
Customer: replied 1 year ago.
WDBTJ65J63F012071 - when I turn the key on, it says "Service A exceeded by 200 miles". When I scroll to the mileage or temp. screen and push the button 3x, no voltage screen. I pushed it 3x pretty fast, but nothing. I tried it with key in 1st position, 2nd position, and nothing worked. I also had all the doors, windows, hood & trunk shut. I tried pushing the reset button when the Service A indicator first appears, but it just goes away and nothing happens.

I also tried it with the instrument cluster totally asleep before I turned the key on, still nothing.
Customer: replied 1 year ago.
It's a simple 3-gauge cluster, clock, speedo, and tach.
Expert:  Lou P. master tech replied 1 year ago.
Ok so you are close !! You have to make sure the "home" screen is displayed. That is the basic odometer screen that will show the mileage and outside temp. So press the page button not the arrows , turn the key on and press the page button (the button with the 2 squares ) doesn't matter which one , just press it until the home screen appears. Then shut the car off. Turn to first click then press the dash button 3 times. Here are the factory instructions

The initial screen showing service due also shows mileage and temperature. Is that the correct screen?
