My truck has 29337 miles on it and I put it to 24000. It went to 14900. I been trying to correct it it but can only get it close.
Is there a possibility that you're setting the mileage in a location that is looking for a value in kilometers?
24,000 km * .625 = 15,000 miles
In the above example;
29,337 miles * 1.6 = 46,939.2 km
I checked active codes and u1412 implausible vehicles speed signal keeps popping up.
This sounds like the tire circumference size is set incorrectly. This condition will also mess up the speedometer and the odometer readings.
Is the speedometer working properly?
I set custom tire sizes for winter and summer wheels and used an old standalone GPS to fine tune the setting.
I'll post the AlfaOBD location for tire size a bit later when I start my PC, using a phone ATM.
