Average fuel consumption – correction factor
The factor follows previous systems, with adjustment range of 750 to 1250. The adjustment method is new for the base cluster. If adjustment is necessary, enter into test 20
using the cluster button. The correction factor number is changed by using the sub-tests
for the “ones, tenths and hundreds of the factor number. The digits will automatically
scroll through 0-9 within each group (ones, tenths, hundreds).
Sub-Tests:
XXX9 20.0 = Press the button when the correct “ones” position is attained.

Test No. 20
BC consumption value correction factor. This test adjusts the correction factor for the
consumption value displayed in the MID. The production line installed value is 1000.
The value ranges from 750 to 1250.
To adjust the correction factor press the trip meter reset button once for a reduction of 1.
For each press of the reset button the value decreases by 1 until it reaches 750. After
750 the number will reset to 1250 and begin to count down again.
To accept the set correction factor press the CC button.
The consumption correction factor (VK) is calculated from the actual amount of consumed fuel (VBR IST) and the displayed value (VBR ANZ):
VK = (Actual MPG / Displayed MPG) X 1000.
