5. Remove the 7.5A fuse (white lead) and check
the presence of voltage
1 - 4 = 0V
YES point 6 NO point 7
6. The lamp control circuit is efficient.
7. Access the instrument unit and disconnect the
8-pin connector. Check the positive insulation of
the connection line to the ECU
1 - 4= 0V
Restore the wiring in case of faults
8. Battery voltage is lacking and the lamp is off.
Access the instrument unit and disconnect the 2
electrical connectors. Check the presence of volt-
age between white lead (+) and black lead (-)
Black (5/5) - White (6/8) = battery voltage with
switch to "ON"
SI punto 10 NO point 9
9. Positive power to panel missing. This comes
from the switch and the 7.5A fuse. Power supply
is shared by the fuel level indicator and other uses.
Restore the wiring continuity.
GO TO point 8
10. Check the instrument panel injection lamp
YES point 12 NO point 11
11. Replace the lamp.
12. Check the continuity of the negative line from
the instrument unit to the ECU
GREY (3/8) - pin 4 = 0Ohm (continuity)
If there is no continuity, restore the wiring.
