I just put 2014 Q50 wheels on my G37. See pics here: https://www.myg37.com/forums/g37-sed...love-them.html

But now I get the dreaded TPMS light. I followed the procedure from the long 24 page thread on how to reset the system and re learn the sensors with no luck. I can get into the learn mode without problem, but after a few minutes I get a long 7-10 second beep and the light turns solid.

Does anyone know if the sensors from the Q are compatible with the computer on the G? I found the following sensor part #s:
- 2010 G37X - 40700-JK00C
- 2014 Q50 - 40700-1LA0B

If these are not compatible, does anyone know how I can get that damn light off? Do I really need to rip out the old sensors from the old rims and install them in the new rims? That seems like it would be a PITA.

Any help is appreciated. Thanks.

 

You need to have those sensors registered to the ECU. Go to any tire shop, and they'll come out to your car with a wireless device and an OBDC connector. Each wheel is wanded one at a time. They'll probably charge you $5/each corner.

 

Cool. Thanks, I'll try that. Do you happen to know if I'll still need to go through the learning process after that (inflating all the tires to different PSI, tapping the wire 5 times, etc, as is listed in the "resetting the TPMS" mammoth thread)? Or should I be good to go after they are registered at the tire shop. I'm just trying to manage my expectations at the tire shop.

 

AFAIK, that dance was last available in 2010, as a way for you to relearn the TPMS all by yourself, without shop support. From what I've read, it's a difficult dance to learn.

Just go to the tire shop. Ask them to relearn your TPMS. Better yet, make some phone calls and get the cheapest price.

 

This is getting more difficult. Went to my local mom and pop tire shop and they had the tool, but it wouldn't read my sensor. "Sensor not found" was the error code on the tool. But he had to type the year and make of the car in the tool, and after it didn't work for 2010 G37, we wanted to try 2014 Q50 (since those are what the wheels came off of). But the software on the tool only went up to 2013, and q50 wasn't even listed as an option.

It looks like I'll need to go to the dealership or a national chain tire shop and hopefully their equipement can "find" my sensors.

 

Might be easier to simply swap in your old TPMS sensors from the wheels you took off (assuming you still have them).

 

At the expense of mounting/balancing all four wheels.

Not all places are the same. One of my local tire shops failed to read my right/rear sensor, but a more high-end street/pro shop had no problem. Newer equipment? Newer software? IDK. For sure your local NISSAN dealership would be able to help, and at a cheaper rate than INFINITI.

 

Easier, yeah, but more expensive. Everywhere around me is $20/tire for mounting/balancing. That $160 for 8 tires (unless I cut upon the old tires and rip the sensors out myself).

Good idea about going to Nissan over infiniti. I'll try that. I just wish this light could be disabled. I don't have a problem with checking my own tire pressure periodically.

 

Which is something OP will have to pay anyway if it turns out the TPMS sensors in the Q50 wheels are incompatible with the G37.

 

Absolutely. They might even charge him for dismounting the tires off the INFINITI wheels just to get the sensors. That said, new sensors aren't cheap. And of course there's the PITA factor of lugging around 4 rims and tires.

All because of a little TPMS light on the dash. LOL

Been there...

 

That's exactly what the service dept at the Infinit dealership told me today. The q50 sensors are not compatible with the g37 ECU. So there you go.

To make matters worse, he said that I might not even be able to swap sensors. He wasn't sure becuse they haven't seen many q50s becasue they are so new. But he said the diameter of the hole for the sensor/stem in the q50 wheel MAY be a different size than the g37 wheel.

Awesome. So it looks like I may be living with the light for the forsseeable future.

 

Did you try Discount Tire? they reprogrammed my G37S coupe wheels to my G35 and it worked, for free too!
