Gas Use From Start/Corr. Factor, Boost Press./Funct. Selec. CK.
Function Selector Switch:
Consumption correction factor (in %), checking
Work sequence
- switch ignition OFF
- press reset button and hold
- switch ignition ON
- release reset button
- press function selector switch and hold until end of display
Correction Factor Display:
- check display
^ correction factor is display (%)
If correction factor is displayed, - check fuel consumption from start (G) (ltr)
Note
The correction range is between 0 and +/- 16%
If the correction factor is a negative number, a minus sign (-) will be displayed. For example: -16 is negative 16:
If the correction factor is a positive number, a positive sign (+) will NOT be displayed. For example: 16 is a positive 16
If the correction range is NOT displayed, - check function selector switch, - repeat test
If consumption correct factor is still NOT displayed, - replace computer
96-815
- select G---> (ltr--->) function with function selector switch
- press reset button for 5 seconds (while driving)
Note
After approximately 3 miles or 3 km, fuel consumption will be displayed in Gal. or ltr.
Fuel Consumption Display:
- check display
^ 0.1 to 0.3 G (0.1 to 1 ltr)
If consumption is displayed, - check boost pressure display
If consumption is NOT displayed, - check fuel consumption sender
- repeat test
If consumption is still NOT displayed, - check computer
Function Selector Switch:
Boost pressure, checking
Work sequence
- switch ignition ON
- select boost pressure display with function selector switch
Boost Pressure Display:
- check display
^ approximately 1.0 bar (this value will vary with altitude)
If boost pressure is NOT displayed, - check boost display control, - repeat test
If boost pressure is still NOT displayed, - repair short circuit using current flow diagram
Function Selector Switch:
Function selector switch, checking
Work sequence
