Checks and inspections

Dashboard

Vehicle X9 has an instrument panel divided into 2 sections: the analogue section fitted in the fairing and

the digital section attached to the handlebars.

The analogue section includes:

- Double scale speedometer (mph-Km/h) control-

led by the phonic wheel vai the ABS cpu and digital

section;

- rpm counter controlled by the signal from the in-

jection cpu;

- Fuel level indicator controlled by a resistive sen-

sor (inside the tank);

- Coolant temperature indicator controlled by a re-

sistive sensor (on the head).

These instruments are electrical and managed

with a stepper motor.

The digital section include the lamps:

- Fuel warning lamp: yellow;

- Parking lights and dipped beams: green;

- High or flashing beams: blue;

- Left turn indicator: green;

- Right turn indicator: green;

- Emergency lights (four indicators): red;

- Engine not on: red;

- ABS fault: yellow;

- Oil pressure: red;

- Injection warning: yellow;

- ALARM (electrohydraulic stand): red.

The petrol reserve warning, turn indicators and

emergency lights are activated by the digital in-

strument panel. For example, the petrol reserve

warning lamp only goes on when the reserve indi-

cation from the tank lasts for at least 13.5 seconds.

This prevents the reserve lamp from going on and

off.


ELE SYS - 17

- Intermittent operation is incorporated in the in-

strument electronics: this makes operation of the

emergency lights possible with the switch in the

"OFF" position and control switch disabled. The

control switch is only enabled with the panel on.

In order to ensure safety when driving, the turn in-

dicator control" function is connected to the odom-

eter. If the driver forgets to turn off the turn

indicator, it is automatically disabled after 1 kilo-

metre of driving.

- The "engine not on" lamp is enabled by the lateral

stand switch and emergency switch located on the

right side of the handlebars.

- The LCD display has a 5 figure indication of the

total travel of the vehicle. This can be expressed

in kilometres or miles: naturally, this figure can

never be reset. To select the indication, with the

ley in the "OFF" position, press the "Trip" and "M"

buttons at the same time, and then turn the ley

switch to the "ON" position; by keeping these 2

buttons pressed for more than 3 seconds, first

"SET" will appear on the display, and then the

change from miles to kilometers and vice versa.

The digital section of the instrument panel is completed with a liquid crystal display and four control

buttons.

The display has 3 icons with the words:

- Oil;

- Service;

- Belt.

If the "Oil" icon flashes, the engine oil needs to be changed.

If the "Service" icon flashes, scheduled servicing indicated on the coupons needs to be effected.

If the "Belt" icon flashes, the drive belt needs to be changed.

Following servicing by an authorised centre, the warning of the icon or icons needs to be cancelled

using the "Reset" button located in the front part of the vehicle under the upper light cover. The "reset"

button is used to reset the mileage for "OIL" and "BELT" and the annual count for "Service". This count

remains enabled even if the battery is disconnected for a short period of time.

To reset one of the icons, go to the icon before the one to reset, press the "Reset" button for less than

1 second, then press the "Reset" button for at least 3 seconds so that the following is displayed:


ELE SYS - 18

- Selection of the desired icon with the lamp going on;

- Flashing of this icon and confirmation of resetting;

For example, to reset the "Service" icon go to "Oil" and press the "Reset" button for at least 3 seconds.

To reset "Oil", repeat the above procedure positioned on "Belt".

It is necessary to repeat this procedure since the icon selection and its resetting are simultaneous

operations (for this operation it is not possible to display the desired function and reset by pressing two

different buttons, because, if this procedure is followed, the following icon would be reset).

ABS LAMP

Each time the key is turned to "ON" the ABS lamp flashes for a few seconds and checks the servo

brakes and part of the ABS check.

The lamp stays on until the ABS and phonic wheel test is finished.

This test occurs when the vehicle exceeds the speed of 5 Km/h with consequent switching off of the

lamp.THE ABS SYSTEM CHECK TAKES PLACE WHENEVER THE KEY IS TURNED TO "ON" AND MAYBE CARRIED OUT AGAIN, ESPECIALLY AT LOW TEMPERATURES, ONCE THE ENGINE ISSTARTED; THIS IS DUE TO THE DROP IN THE BATTERY VOLTAGE CAUSED BY THE ENGINESTART-UP. REPETITION OF THE CHECK, DUE TO LOWERING OF THE BATTERY VOLTAGEDURING THE STARTING PHASE, CAUSES THE "ECU POWER" CODE FTE 5 ERROR, BUT DOESNOT CAUSE UPDATING OF THE "ABS ERROR" FIELD UNDER THE "PARAMETERS" MENU.

Phonic wheel

Checking the phonic wheel circuit

• Disconnect the phonic wheel connector.

• -Disconnect the ABS cpu connector.

• Check the continuity of the green wire between

PIN 12 of the cpu connector and the connector for

the phonic wheelN.B.To make the connection on the phonic wheel connectorside use a pin placing it gently on the connector terminal.Completely inserting the pin causes permanent deforma-tion of the terminal.It is advisable to use tester wires with clamps

• Check the continuity of the grey wire between

PIN 21 of the ABS cpu connector and the connec-

tor for the phonic wheel.

• Check the isolation towards the earth of the lines.


ELE SYS - 19

Electric characteristicPIN 12 ÷ PIN 24= OHM Infinitive


• Check the isolation from positive of the lines with the key switch in "ON" position

Electric characteristicPIN 12 ÷ PIN 24= 0 Volt

Electric characteristicPIN 21 ÷ PIN 24= 0 Volt

• Check the isolation between the two lines


ELE SYS - 20


If faults are found replace the wiring.

• Reconnect the ABS cpu connector.

• Keep the phonic wheel connector disconnected.

• Turn the key switch to "ON"

• Check that between PIN 12 (Green wire) and the

earth that battery voltage is present (a slight volt-

age drop of around 0.5V is allowed)

• Position the key switch to "ON"

• Connect the multimeter to the battery positive,

and check that the earth is present at PIN 21 (grey

wire).

• Keep the key switch in the "ON" position.

• Short PINs 12 and 21 with the ends of the multi-

meter in ammeter function.

• Make sure there is a current of around 20 mA.


ELE SYS - 21

• Keep the key switch in the "ON" position.

• Using the phonic wheel connector short PINs 12

and 21.

• Measure the positive voltage of the short using

the multimeter.

Standard value = battery value (a slight drop in

voltage of around 0.5 V is allowed)

• Check the voltage of the speed sensor indicated in the parameters menu

Speed sensor voltage

Electric characteristicSP. SEN VOL.around 2,8 V

If faults are found replace the wiring.

If voltage faults are found check the ABS cpu power circuit.

If no power faults are found check operation with a new modulator.

If the phonic wheel signal continues to be faulty and the voltmeter and ammeter checks do not reveal

any faults, replace the phonic wheel and repeat the operating test

ENABLED DIAGNOSISSpecification Desc./Quantity

PUMP MOTOR Enables the modulator pump for around 20 seconds.BRAKE LIGHT Changes the status of the brake light for around 15 seconds.

E.g. in normal operating conditions the brake light goes on.In the event of brake light always on (error C2) the cpu turns

off the light.INSTRUMENT PANEL LAMP Changes the status of the ABS lamp. The lamp returns to the

initial status, when a key is pressed at the end of the test. Eg.In normal operating conditions the lamp goes on, if the lamp

stays on (error C6) the cpu turns it off.SPEEDOMETER TEST Controls the analogue speedometer needle up to a speed of 5

Km/h for around 5 seconds.

CANCELLING ERRORS This function is used to cancel faults and any codes recorded by the auto-

diagnosis of the ABS cpu.

This function does not reset the "ABS ERROR" and "BRAKE ERROR' in the "PARAMETERS" menu.

MEMORISED PARAMETERS This function is used to display previously memorised parameters.

As previously explained in the description of the parameters function, memorisation is effected by

pressing the "TAB" key at the desired time.

The diagnosis tester can only contain one memorisation.

This is automatically deleted when the tester power is turned off.

PIN INITIALISATION Enable PIN INITIALISATION to memorise the vehicle code (if compatible) on a

cpu based on the status of pins 19, 20 and 22.

All the parameters can be displayed by displaying the 3 pages.

If necessary, all the parameters can be memorised in the tester by pressing the "TAB" key when you

want.

The parameters stay memorised as long as the diagnosis tester power is on.

If the "ECU POWER" error is present in the error menu in memorised (M) status, the "BRAKE ERROR"

and "VEHICLE ON" parameters need to be checked.

If an error other than voltage decrease occurs when the engine is started, the lamp on the instrument

panel goes on and "BRAKE ERROR" will appear where the lamp goes on.

If this occurs follow the type "B" troubleshooting procedure.

If the "BRAKE ERROR" is not present in the "PARAMETERS" menu or if it is unreliable (e.g. occurred

a long time ago, probably due to a previous problem), the "POWER ERROR" is due to the natural

decrease in battery voltage when the engine is started.

This voltage decrease may cause the ABS system check to be repeated, for this reason the following

note appears on the vehicle use and maintenance handbook:

THE ABS SYSTEM CHECK TAKES PLACE WHENEVER THE KEY IS TURNED TO "ON" AND MAYBE CARRIED OUT AGAIN, ESPECIALLY AT LOW TEMPERATURES, ONCE THE ENGINE ISSTARTED; THIS IS DUE TO THE DROP IN THE BATTERY VOLTAGE CAUSED BY THE ENGINESTART-UP.

N.B.

DURING THE BLEEDING OPERATIONS, MAKE SURE THE BRAKE FLUID DOES NOT COME INTOCONTACT WITH THE BODYWORK SO AS NOT TO DAMAGE IT. FURTHERMORE, DURING THEBLEEDING OPERATIONS REGARDING THE BRAKE CALLIPERS, MAKE SURE THE BRAKEFLUID DOES NOT COME INTO CONTACT WITH THE DISC BRAKES AND WITH THE BRAKEPADS. FAILURE TO OBSERVE THIS PRECAUTION WILL ENDANGER THE PROPER WORKINGAND EFFICIENCY OF THE BRAKING SYSTEMN.B.

IF AIR CONTINUES TO COME OUT DURING THE BLEED OPERATION, EXAMINE ALL THE FIT-TINGS. IF SAID FITTINGS DO NOT SHOW SIGNS OF BEING FAULTY, LOOK FOR THE AIR INPUTAMONG THE VARIOUS SEALS ON THE PUMP AND CALLIPER PISTONS. WHEN CARRYING OUTTHE OPERATION, BRAKE FLUID MAY LEAK FROM THE BLEED SCREW ON THE CALLIPER ANDON THE DISC. IN THIS CASE; CAREFULLY CLEAN THE CALLIPER AND DEGREASE THE BRAKEDISC.

Start the procedure by bleeding the brake calliper.

- Loosen the bleed screw shown in the photo and

activate the left brake lever until only brake fluid

comes out

- Close the bleed screw

- Activate the left lever several times

- Keeping the lever activated, loosen the bleed

screw and make sure only brake fluid comes out

- Top up the liquid in the reservoir

Proceed with bleeding of the check valve

- Remove the rubber cap shown in the photo

- Insert the spanner as shown in the photo


BRAK SYS - 54

- Apply the rubber tube as shown in the photo

- Loosen the bleed screw

- Activate the left brake lever until only brake fluid

comes out of the bleed screw

- Close the screw




Proceed with bleeding of the modulator- Apply the

rubber tube

- Loosen the shortest bleed screw on the modula-

tor shown in the photo



- Close the screw

Start the procedure with the modulator

- Loosen the longest bleed screw on the modulator

shown in the photo

- Activate the right brake lever until only brake fluid


- Close the bleed screw- Activate the right brake

lever several times

- Keeping the brake lever activated open the bleed



Proceed with bleeding of the brake calliper

- Loosen the bleed screw shown in the photo

- Activate the right brake lever until only brake fluid


- Close the bleed screw - Activate the right brake

lever several times

- Keeping the brake lever activated open the bleed



Proceed with internal bleeding of the modulator

- Remove the low pressure tube from the oil tank

cap on the modulator as shown in the photo and

plug the end of the tub with a tapered cap

- Remove the stop collar and the modulator tank

cap as shown in the photo

- Using the diagnosis tester, under enabled diag-

noses, activate the modulator internal pump. This

bleeds the inside of the modulator

- Top up the level of the modulator tank if needed


BRAK SYS - 56

After bleeding the modulator it is likely that part of

the air present in the circuit will get into the tube

between the pilot valve and brake calliper. Thus it

is necessary to proceed with bleeding of the tube.

- Get a transparent tube long enough to connect

the bleed valve on the calliper and the brake fluid

reservoir on the modulator.

- Apply one end of the tube to the bleed valve on

the calliper as shown in the photo

- Remove the filter inside the brake fluid reservoir

as shown in the photo

- Keep the other end of the tube on the outlet of

the modulator reservoir

- Loosen the bleed valve on the brake calliper

- Enable the pump using the diagnosis tester

- With the pump enabled, activate the right brake

lever in order to increase the pressure in the tube

to bleed

This will cause all the fluid in the tube to come out

and any air that got in when the modulator was

bled and then the brake fluid left in the circuit.

- Close the bleed valve on the brake calliper

- Refit the filter on the modulator reservoir

- Completely fill the modulator reservoir

- Refit the cap on the reservoir with the stop collar

- Refit the low pressure tube on the reservoir cap
