Example of data from VDO instrument cluster, measuring value block 002:
- Enter display group number 002 by pressing button -0- twice and -2- once.
Indicated on display:
Read measuring value block 2 ->
820 km 41/19.0
VDO measuring value block 002:
Displayed value Designation
820 km 1 = Distance travelled
41 ltr. 2 = Fuel gauge
19.0 °C 3 = Ambient temperature
Example of data from Magneti-Marelli instrument cluster (M73) measuring value block 002:
- Enter display group number 002 by pressing button -0- twice and -2- once.
Indicated on display:
Read measuring value block 2 ->
820 km 41/250 ohm 19.0°
M73 measuring value block 002:
Displayed value Designations
820 km 1 = Distance travelled
41 ltr. 2 = Fuel gauge
250 ohm 3 = ohm Value of fuel gauge sender -G-
19.0°C 3 = Ambient temperature in °C
NOTE:
- Display fields always show actual values transmitted from senders and sensors. However, instrument cluster display values can differ from those in the display fields due to internal filtering.
- The coolant temperature gauge will steadily indicate 90 °C (194 °F) if the actual coolant temperature varies between approx. 75 °C (167 °F) and 107 °C (225 °F).
- For vehicles with VDO instrument cluster and open or short circuit in fuel gauge sender, display field 2 displays "0 L" and field 3 remains vacant. For vehicles with a Magneti-Marelli instrument cluster (M 73) display field 2 displays "2 L" for short circuit and 67 L for open circuit. Display filed 3 displays 8 ohm for short circuit and > 350 ohm for open circuit.
- Other display groups are possible, but are not required for On Board Diagnostic program!
