Discuss Tire Registration function of Battery App

Fri Aug 16, 2013 12:12 pm

Please use this topic to discuss the Tire Registration function in the Leaf Battery App.

The Tire Registration function is currently in beta test.

Since the Battery App displays the four tire pressures it is important that the tires' positions on the car be correctly registered so a low pressure tire can be correctly located without needing an external guage.

Each time the tires are rotated their position changes and a registration should be performed. This has required a visit to the dealer and so is not normally done. Also the Leaf does not display the actual tire having the low pressure so position was not important. The Battery App has changed all that and so it makes sense that the app include a function to correctly register the tires.

Three things are required to perform a tire registration.

1. Source of air
2. Skill of adding/releasing air from the tires
3. Pressure guage

The steps are:

1. Adjust each tire pressure as follows (position relative to sitting in the car).
* Front Left 35 PSI
* Front Right 32 PSI
* Rear Right 29 PSI
* Rear Left 26 PSI

2. Start App and go to Setting/Debug panel and check the "Service" checkbox. Exit Settings menu and Service panel will be displayed.

3. Drive Leaf unit PSI values are updated. If the order is highest to lowest PSI then the tires are correctly registered skip to step 6.

4. If the pressures are not in high to low order then press the "Start Tire Reg" button. Confirm that pressures have been adjusted to the four required values. Confirm that you are ready to drive at or above 25 MPH for 3 or more minutes. Start driving.

5. In about 3 minutes the button should change from Yellow back to Green. During this time the dash tire pressure icon will be blinking. When registration is complete it will go away but after a few minutes will come back because the rear left tire has low pressure.

6. Adjust all tires back to spec (36 PSI) or whatever value you use.


Post here your results and which model year you have.

Tried it this morning on my 2011 and it worked as designed.

I'm probably going to take a less labor intensive route in the future though by simply marking each tire with RR, RF, etc. somewhere where it is normally not visible so I can keep track of what is where after each rotation and relate that to the display...

For those interested, the part number for the TPMS is currently
40700-1LA0D

It was preceded by 40700-1LA0C, but might have also been 40700-1LA0A and/or 40700-1LA0B, but no guarantees.

I found one after market one for 65$ea at http://www.carid.com/nissan-leaf-tpms-sensors/" onclick="window.open(this.href);return false;
the part number for this one is OPA-LA0A, more info on other compatibility is listed here http://www.orotekusa.com/TPMSSensors.aspx" onclick="window.open(this.href);return false;

Has anyone had luck with non-oem sensors?
might be too early to ask this question.

Thanks for the info, jclemens. I didn't bother getting another set of TPMS for my winter wheels, but now that I can re-register them myself, I might do so.

Worked perfectly this morning on my 2012 SV.
Here are the results after re-registering my TPMS sensors:

It's Turbo3's LEAF Battery App for Android only so you won't find it at any of the 'stores'. There's a long thread about it plus Stoaty did a Wiki on it. He has a link with his sig.

Is there any other reason to do this than the display in the app? I am close enough to tire rotation/change and I will rather wait until after that.

The app is now called LEAF Spy, and is on the Google "Play Store"
for Android devices. The Lite version is free, to test that it works
on your Android phone/device and with your OBD dongle.

No real need to reset the tire sensor locations, but you can
whenever you feel like fussing with the Tire pressures.

Registering new sensors is nice to make the reading of
tire pressures work correctly, both for the car's warning
light, and for the app's displayed pressure values.

Thank you for the info. I already got it, the Pro version. I did not want to start a new tread about the tire registration function.

No, doing it just keeps the apps tire pressure numbers in sync with where the tires actually are on the Leaf. So if a pressure is low you know which tire needs air. Or if slowly decreasing, which one might have a nail in it.
