The display now shows the counter 1 (odometer in this example) data. The number on the top
line represents the initial programmed whole odometer. The bottom left shows the ratio, and
the bottom right shows the current VM odometer. If the true ratio was not known at the time
the VM was installed, the current VM odometer probably does not match the dashboard
odometer.

The longer a vehicle is driven, the more accurate the calibration calculation becomes. For a
very accurate calibration, run the calibration, then drive the vehicle for the duration of your
normal scheduled vehicle maintenance. Then check calibration for accuracy. Change ratio if
needed according to the criteria in Step 7.

At this point you need to determine if you will make any changes to the odometer and/or ratio,
based on the criteria that follows:
• If the current VM odometer matches the dashboard odometer, you do not need to make
any changes. If this is a Single VM (only 1 counter field), you can turn the Programmer off
and end this session. If it is a dual VM and counter 2 is used for odometer, press ENTER
twice to advance to counter field 2. Perform these same three criteria checks on counter
field 2.

VM matches dashboard
• If the difference between the current VM odometer and dashboard odometer is within 1
percent the total dashboard miles driven so far, the ratio is already very accurate and you
only need to update the mileage, not the ratio. Proceed to the section

VM within 1% of dashboard
• If the difference between the current VM odometer and the dashboard odometer is greater
than 1percent of the total dashboard miles driven so far, you need to update both mileage
and ratio. Proceed to the section
“Updating the Odometer and Ratio” on page 5-17.
