I had a couple of cases where the camera picked up 40mph access road signs and slammed on the brakes, so I just disabled it entirely.

Fairly certain the camera has nothing to do with it. Traffic Recognition is a mis-advertised marketing gimmick (unless if the software works different for American customers).

In Canada, road speed data is fed by whatever is in the Nav unit.
Consider it more like budget-traffic-recognition.

For example: if I drive in a construction site or area where the physical posted limit has recently been changed, the truck's IPC will continue to display old false information of whatever is in the APIM NAV.

The camera in my truck for sure doesn't read road signs in my region.

Mine reads the speed limit in my company’s parking lot. Not regulation size or height. It goes from 45 to 15. Does it read all signs or read them correctly? No. But it does recognize white speed limit signs with black lettering.

Is there one to allow the front camera at speed?

Your guess is as good as mine. I think @antho did it at one point.

Looking for this as well. Was really hoping to enable front camera at speeds above 2mph...

Interesting, I figured it would work just the same in the great north and would read the speed signs with the camera all the same right when you pass them, but maybe not for some reason. So if it just relies purley off nav speed changes, ya, that gets rather interesting.

The front camera at speeds only works on mine in Baja mode and maybe rock crawl? That was from factory though.

Has anyone else who has adjusted the tire size had to go quite a bit smaller on the circumference hex value in order to achieve the proper speedo readings? My winter tires circumference is 2520mm and I had to input the hex value into the low 2400's to even get close at highway speeds.

Thanks in advance.

The multiplier is .967

I believe the multiplier is .967 or .976, you can search for it. You can find it by backwards calculating stock tire size v stock number in the truck.

Ah ok, I never caught that multiplier. I cross referenced the original tire circumference to the original hex value and that was off also, so that makes sense now.

Thanks!!

No wonder my speedo is off by 1-2 mph after I recalibrated when I swapped out my wheels/tires. Good to know.

Mine is way off too since I got my new tires. I’m not completely understanding this but now I need to try to figure it out

Use a decimal to hexadecimal converter to get the circumference (mm) in hex after first multiplying the mm by the .967 or whatever it is. Then input that hex value into the 2 lines on the BCM. I just had to trial and error until it read ok.

So I have this same issue but my handheld tuner can adjust speedo by entering in the tire revolutions per mile. Mine is 602 revolutions per mile for my 35x12.5x20 bf Goodrich’s KO2’s.
so dividing 602/.967 I should use 622 as my value instead of 602 to get a more accurate Speedo? I’m off by under 2mph as well using the documented 602 number from bf Goodrich in my case.

Give it a shot and see what happens v. GPS. The factory speedo is typically conservative by 1 mph indicated to mitigate claims of "my speedo is wrong and I got a ticket". Just about every vehicle I've owned indicates ever-so-slightly faster speed. Confirm it's recording mileage properly by driving a calculated route via mapping software.

The multiplier is .967

Thank you!
