6.10.3 COOLANT TEMPERATURE DISPLAY

NOTE
In the event the message "
right-hand display, with a temperature below 130 °C (266
°F), there might be a problem with the wiring or the coolant
thermistor might have short-circuited (right-hand side of
engine, see 6.4.8 (CHECKING THE COOLANT THER-
MISTOR OPERATION).
Lift the fuel tank, see 2.8 (LIFTING THE FUEL TANK).
Disconnect the two-way connector (1) (coloured green)
from the thermistor (2) (right-hand side of the engine).

tor on the right-hand side of the engine, see 6.4.8
(CHECKING THE COOLANT THERMISTOR OPERA-
TION).
6.10.4 CHECKING THE ENGINE OIL LOW PRESSURE
SENSOR
Remove the lower fairing, see 7.1.32 (REMOVING
THE LOWER FAIRING).
Slip off the rubber protection (3).
Disconnect the electric terminal (4) from the sensor (5)
and earth it.
a
CAUTION
When reassembling, make sure the electric terminal
(4) is connected properly.
With the ignition switch set to "
j
oil pressure " " LED should come on.

If the " " LED comes on as expected, check the sen-
sor is working properly.
With a tester (scale x 100 Ω) check for breaks between
the tongued terminal (6) and the casing of the sensor
(5) (see figure).
Correct value with engine off: 0 Ω.
Correct value with engine running:
If the values do not correspond to those indicated, check
that the engine oil level is correct, see 2.13 (CHECKING
THE ENGINE OIL LEVEL AND TOPPING UP) and
change the sensor (5), if necessary.
