Fault code
FMI 3
Abnormally high voltage or short-circuit to higher voltage.
Conditions for fault code:
•
If the instrument cluster registers a resistance
greater than 250
the instrument cluster interprets
this as a fault and a fault code is stored.
Possible cause:
•
Open-circuit in the ground lead.
•
Open-circuit in the signal cable.
•
Signal cable short-circuited to higher unladen volt-
age.
•
Faulty sensor.
•
Contact resistance and oxidation.
Reaction from the instrument cluster:
•
fault code is stored.
•
Yellow lamp requested.
Noticeable external symptoms:
•
Yellow lamp lights up.
•
The fuel level gauge remains permanently at the
MIN position.
•
The display shows an icon and the text ”NO DATA”.
Appropriate check:
•
“MID 140 PID 96 Fuel Level, Check” page 24.
FMI 4
Abnormally low voltage or short-circuit to lower voltage.
Conditions for fault code:
•
If the instrument cluster registers a resistance of
less than 20
the instrument cluster interprets this
as a fault and a fault code is stored.
Possible cause:
•
Signal cable short-circuited to ground.
•
Faulty sensor.
Reaction from the instrument cluster:
•
fault code is stored.
•
Yellow lamp requested.
Noticeable external symptoms:
•
Yellow lamp lights up.
•
The fuel gauge remains in the MAX position.
•
The display shows an icon and the text ”NO DATA”.
Appropriate check:
•
“MID 140 PID 96 Fuel Level, Check” page 24.
