INSTRUMENT PANEL WATER SENSOR
Connect a resistance between the two connections of
the connector as shown in the table. Turn the ignition
key to the "ON" position.
At this point the display should indicate the
Temperature relative to the resistance applied.
It is sufficient to carry out the test at 50° C and at 100°
C with the respective resistances of 1.150 kOhm. and
0.204 kOhm.

KEY IGNITION SWITCH
If there is no 12V input between pin (9) and (20) of the
instrument panel connector with ignition switch in the
“ON” position, the cause can be identified by a fault in
fuses 13 or 3.
If the fuses are in good condition, check the continuity
between the pin (9) of the instrument panel and the pin
(15) of the fuse box connector and between the pin
(10) of the instrument panel and the pin (12) of the fuse
box connector.
STARTER RELAY ACTIVATION
- Check that there is a 12V input between pin (11) and (20)
with the safety switch in the “RUN” position and the starter
button pressed.
- If there is no voltage, check the presence of voltage input
between pin (12) and (20).
- If there is no voltage input between pin (12) and (20),
check the condition of fuse E5 after which check the right
hand control as follows:
1) Disconnect the connector of the right hand control;
2) Check the continuity between the contacts (1) and (3)
with the safety switch in the “RUN” Position and the starter
button pressed.
3) Having verified the good functioning of the right hand
control, the cause can be identified as damage to the
instrument panel.
