6.10.3 COOLANT TEMPERATURE DISPLAY
NOTE
In the event the message" L L L", appears on the
right-hand display, with a temperature below 130°C (266
OF), there might be a problem with the wiring or the coolant
thermistor might have short-circuited (right-hand side of en-
gine, see 6.4.8 (CHECKING THE COOLANT THERMIS-
TOR 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).

6.10.4 ENGINE OIL PRESSURE SENSOR
• Remove the right fairing, see 7.1.25 (REMOVING THE
SIDE FAIRINGS).
• Slip off the rubber protection (3).
• Disconnect the electric terminal (4) from the sensor (5)
and earth it.
When reassembling, make sure the electric terminal
(4) is connected properly.
• With the ignition switch set to "0 ", the red low engine
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
Q)
check for breaks between
the tongued terminal (6) and the casing of the sensor
(5) (see figure).
Correct value with engine off: 0
Q.
Correct value with engine running:
00
Q.
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.
