Hi all,


I recently bought a second FR-S, a 2015 Canadian example purchased from a dealer in NY who imported it. As a courtesy before delivering it to me, they had the Canadian instrument cluster reprogrammed to display the odometer in miles rather than km's.

They did not notice, however, that the odometer stopped working. It's stuck at the mileage it was programmed to display. I noticed this on my first test drive after the car was shipped to me. The trip odometers tick up by a few tenths of a mile but then reset themselves. They do this repeatedly.

The dealer was very apologetic and agreed to pay for what's necessary to fix this. I got in touch with a local speedometer shop, who suggested that the easiest thing to do would be to get a US cluster and program it with the correct mileage.

So I had them do that and installed the US cluster. Unfortunately, it behaves just like the reprogrammed Canadian cluster did: the odometer is stuck, and the trip odometers repeatedly tick up by a few tenths and then reset themselves. And like the reprogrammed Canadian cluster, the non-odometer-related functions work: the speedometer, thermometer, fuel and coolant gauges, in-gear indicator, and rev alarm all work. Remote locking/unlocking work as well.

The next thing I did was take it to a Toyota dealer to see if they could find out what the issue is. They kept the car for much of a day, and determined that it's not a hardware issue. The ABS sensors, from which both the speedometer and odometer get their signal, are fine, and the entire CAN BUS network is sending signals just fine. There are no DTC codes.

There was a Techstream initialization procedure that's supposed to be done when a new instrument cluster is installed, to pair it to the key transponder, so they did that. But the remote locking/unlocking worked before the initialization in any case, and this initialization procedure did not get the odometer to work.

After discussing with the dealer's master tech, who worked on the car, we decided that the next steps to try are:

1) Get a US ECU and see if that gets the US odometer to work;
2) If that doesn't work, get an un-modified Canadian instrument cluster and pair that with the Canadian ECU.

The tech was not optimistic about 1) working. He said he's seen other instances of Canadian Toyota models (not FR-S's though) whose installed US odometers were never able to be made to work, even after installing a US ECU.

I have a US ECU on the way and will try that first, since I'd prefer to have an odometer that displays in miles.

Has anyone here had experience with getting a US instrument cluster to work in a Canadian car, or vice versa, or know whether this is even possible? And if it is possible, what steps are needed?

Thanks for reading this long post and for any suggestions!
