Reset 2009 Gas Gauge

Trying to reset my gas gauge - which has really never been quite right. 2009 Prius, and I'm following these instructions (that were posted elsewhere on the forum) to reset:

Ok everybody,sorry this has taken to long. Been busy with a lot of things going on and I forgot. I had a new 2G Prius in for PDI and decided to give it a try. And guess what,I found out what we were doing wrong! Just one little step messes up everything. Here is the steps from the TSB and only applies to the 2G.​

​

1. Park the vehicle so as it is level,front to back and side to side.​

2. IgOn and make sure that "Trip A " is showing on the odo ( this is where we made a mistake).​

3. Power down.​

4. Keep your foot off the brake.​

5. Push in and hold down the Odo/Trip button.​

6. Push the Power button twice to IgOn ( not Ready mode ).​

7. Turn the Odo/Trip off then On 3 times in 5 seconds.​

8. Continue holding the Odo/Trip button until a 6 digit code appears.​

9. Release,then push again the Odo/Trip button for another 5 seconds. The 6 digit code will change to a 5 digit code.​

10. After the middle digit,of the 5 digit code,changes to "1" release the Odo/Trip button and the odometer will return to normal reading.​

​

​

Everything is fairly clear, except step 7. "Turn the Odo/Tripo off, then on 3 times in 5 seconds". There is no "off", then "on". There is simply a toggle between ODO/TripA/TripB. So, are we simply pressing the ODO/Trip button 3 times? Or cycling back to TripA 3 times, or ?????

Can someone be a bit clearer about what this means?​
