Change the tire scale factor

This function is used to change the tire scale factor, so that the speed in relation to the current tire size is correct.
Note:
The speed and distance unit that you select in the function is the unit that the ECU, after completed function, will use from now on.
See the table below for the correct tire scale factor.
Equation for other tire sizes, which is not found in the table below: Tire scale factor = N x (T/100).
N = rev/km.
T = Number of teeth on the tooth wheel.
Test conditions:
Procedure:
  1. Start the function.
  2. Check test conditions.
  3. Check current status.
  4. Select unit.
  5. Enter the desired scale factor.
  6. Check the new current status.
  7. Function done.
