Neutral indicator light
To check the neutral light switch (3) proceed as follows:
A
B
C
The neutral light does not illuminate on the instrument panel.
Remove the electric terminal connected to the neutral switch. Switch on the ignition switch (ignition key to ON position) and
ensure that the light illuminates when the terminal is earthed. If the light switches on, the neutral light switch should be changed.
D
If the light stays off, switch off the ignition (ignition key set to OFF) to switch off the instrument panel and check for electric
continuity between neutral switch and engine control unit with a multimeter.
The neutral light on the instrument panel is permanently illuminated.
Switch on the ignition (ignition key set to ON) and remove the electrical terminal from the neutral switch. If the light switches off,
the neutral light switch should be changed. If the light stays off, switch off the ignition (ignition key set to OFF) and use a
E
multimeter to check whether the section of circuit between neutral switch and engine control unit is earthed.
Oil pressure sensor
To test the operation of the engine oil pressure sensor (4), proceed as follows:
F
G
H
Use the tester to check that oil pressure into engine oil circuit complies with the specified values (Sect. D 5, Checking the engine
oil pressure).
If the engine oil pressure value is outside the specified range, check the oil circuit components and service as necessary.
If engine oil pressure value is within the specified range and the oil pressure warning light on the instrument panel stays off,
switch on the instrument panel (ignition key set to ON) without starting the engine, and disconnect the electrical terminal from
L
the pressure sensor and connect it to earth. If the warning light now illuminates, this means the sensor is defective and must be
replaced. If the indicator light fails to illuminate, use a multimeter and check for electrical continuity in the section of the circuit
between sensor and warning light on the instrument panel (this check must be performed with the ignition key set to OFF, i.e.
with instrument panel off).
If the engine oil pressure complies with the stated values and the engine oil pressure warning light on the instrument panel is
M
continuously illuminated, switch on the instrument panel (ignition key set to ON) and start the engine, then disconnect the
electrical terminal normally inserted on the pressure sensor. If the warning light now switches off, this means the sensor is
defective. If the warning light fails to switch off use a multimeter and check that the section of the circuit between sensor and
warning light on the instrument panel is not connected to earth (this check must be performed with the ignition key set to OFF,
i.e. instrument panel off).
