Hello,
I'm new to Forscan and have a question regarding adjusting the tire size to calibrate the speedometer. I have a 24 350 Platinum with 37" tires. I followed the spreadsheet supplied here and adjusted the tires size to 2781mm, which puts the spedo spot on. I think stock it was set to 2650ish. This is literally the only thing that I adjusted. Upon writing the new tire size value I found that now the 'check engine' light is on and also the 'service engine soon' light as well as a service engine soon and check 4x4 warning at start up.
Is there a way to bypass the warning lights in order to maintain the correct tire size? I'm assuming that the new value is out of Ford's spec, thus triggering the lights.
Any ideas or advise would be greatly appreciated!
