Fault code
FMI 3
Abnormally high voltage or short-circuit to higher voltage.
Conditions for fault code:
•
If the instrument cluster registers a voltage greater
than 4.5 V 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 voltage.
•
Faulty sensor.
•
Contact resistance and oxidation.
40
Reaction from the instrument cluster:
•
Fault code is stored.
•
Yellow lamp requested.
Noticeable external symptoms:
•
Yellow lamp lights up.
•
The display shows an icon and the text "NO DATA".
Appropriate check:
•
"MID 140 PID 177 Transmission Oil Temperature,
Check" page 41.
FMI 4
W3005588
Abnormally low voltage or short-circuit to lower voltage.
Conditions for fault code:
•
If the instrument cluster registers a voltage of less
than 0.5 V 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 display shows an icon and the text "NO DATA".
Appropriate check:
•
