This section describes the general specifications of the vehicle.
Rules
This section describes general safety rules for any maintenance operations performed on the vehicle.
Safety rules
- If work can only be done on the vehicle with the engine running, make sure that the premises are well ventilated, using special extractors if necessary; never let the engine run in an enclosed area. Exhaust fumes are toxic.
- The battery electrolyte contains sulphuric acid. Protect your eyes, clothes and skin. Sulphuric acid is highly corrosive; in the event of contact with your eyes or skin, rinse thoroughly with abundant water and seek immediate medical attention.
- The battery produces hydrogen, a gas that can be highly explosive. Do not smoke and avoid sparks or flames near the battery, especially when charging it.
- Fuel is highly flammable and it can be explosive given some conditions. Do not smoke in the working area, and avoid naked flames or sparks.
- Clean the brake pads in a well-ventilated area, directing the jet of compressed air in such a way that you do not breathe in the dust produced by the wear of the friction material. Even though the latter contains no asbestos, inhaling dust is harmful.
Maintenance rules
- Use original PIAGGIO spare parts and lubricants recommended by the Manufacturer. Non-original or non-conforming spares may damage the vehicle.
- Use only the appropriate tools designed for this vehicle.
- Always use new gaskets, sealing rings and split pins upon refitting.
- After removal, clean the components using non-flammable or low flash-point solvents. Lubricate all the work surfaces, except tapered couplings, before refitting these parts.
- After refitting, make sure that all the components have been installed correctly and work properly.
- For removal, overhaul and refit operations use only tools with metric measures. Metric bolts, nuts and screws are not interchangeable with coupling members with English measurement. Using unsuitable coupling members and tools may damage the vehicle.
- When carrying out maintenance operations on the vehicle that involve the electrical system, make sure the electrical connections have been made properly, particularly the ground and battery connec­tions.

Vehicle identification
Chassis prefix (A)
ZAPM642001
Engine prefix (B):
M474M
The identification registration numbers consist of a prefix stamped on the chassis and engine "B" respectively, followed by a number. These num­bers must always be indicated on spare parts re­quests. To read the chassis number, remove the relevant port "A" in the helmet compartment. We recommend checking that the chassis registration number stamped on the vehicle corresponds with that on the vehicle documentation.
CAUTION
BE REMINDED THAT ALTERING IDENTIFICATION REGIS­TRATION NUMBERS CAN LEAD TO SERIOUS PENAL SANCTIONS (IMPOUNDING OF THE VEHICLE, ETC.).

Checking the spark advance
The ignition advance is determined electronically on the basis of parameters known by the control unit. For this reason it is not possible to interpret the reference values based on the engine rpm. The ignition advance value is detectable at any time using the diagnostic tester. It is possible to check whether the ignition advance determined by the injection system matches the value actually activated on the engine, by means of the strobo­scopic light.
Proceed as follows:
- Remove the spark plug.
- Remove the transmission crankcase.
- Rotate the driving pulley fan until the reference marks between the flywheel and flywheel cover meet as shown in the photograph.
- Bring the reference mark onto the transmission side between the fan and the transmission cover as shown in the photograph.

- Refit the spark plug.
- Refit the plastic cap on the flywheel cover.
- Adjust the spark gap to the contact position (no
reference mark visible) and install it on the engine between the spark plug and spark plug cap
- Connect the induction clamp on the spark gap
cable respecting the proper polarity (the arrow on the clamp must be pointing at the spark plug).
- Connect the diagnostic tester.
- Start the engine.
- Select the «parameters» function in this menu.
- Select the stroboscopic light control in the tradi-
tional four-stroke engine position (1 spark, 2 revs).

Engine oil
In four stroke engines, the engine oil is used to lubricate the distribution elements, the bench bearings and the thermal group. An insufficient quantity of oil can cause serious damage to the engine. In all four stroke engines, the deterioration of the oil characteristics, or a certain consumption should be considered normal, especially if during the run-in period. Consumption levels in particular can be influenced by the conditions of use (e.g.: oil consumption increases when driving at "full throttle".
Replacement
Change oil and replace filter as indicated in the scheduled maintenance table. Empty the engine by draining the oil through drainage plug «B».
To facilitate oil drainage, loosen the cap/dipstick «A».
MP3 500 ie SPORT Business LT (2011) Maintenance
MAIN - 41
Page 42
Once all the oil has drained through the drainage hole, unscrew and remove the oil cartridge filter «C ».
Make sure the pre-filter and drainage plug O-rings are in good conditions. Lubricate them and refit the mesh filter and the oil drainage plug, screwing them up to the prescribed torque. Refit the new cartridge filter being careful to lubri­cate the O-ring before fitting it. Change the engine oil. Since a certain quantity of oil still remains in the circuit, engine oil must be added through plug «A». Then start the vehicle, leave it running for a few minutes and switch it off: after five minutes check the level and if necessary top up without exceeding the MAX level. The cartridge filter must be replaced every time the oil is changed. Use new oil of the recommended type for topping up and changing purposes.
N.B. THE ENGINE MUST BE HOT WHEN THE OIL IS CHANGED.

Check
This operation must be carried out with the engine cold and following the procedure below:
- Place the vehicle on its centre stand and on flat ground.
- Unscrew the cap/dipstick «A», dry it with a clean cloth and reinsert it, screwing it all the way down.
- Remove the cap/dipstick again and check that the level is between the min and max reference marks; top-up, if required. If the check is carried out after the vehicle has been used, and therefore with a hot engine, the level line will be lower; in order to carry out a cor­rect check, wait at least 10 minutes after the en­gine has been stopped so as to get the correct level.
Oil top up
The oil should be topped up after having checked the level and in any case by adding oil without ever exceeding the MAX. level. Restoring the level from the MIN to the MAX marks requires approx. 400 m³ of oil.
Engine oil filter
The cartridge filter must be replaced every time the oil is changed. Use new oil of the recommended type for topping up and changing purposes. Make sure the pre-filter and drainage plug O-rings are in good conditions. Lubricate them and refit the mesh filter and the oil drainage plug, screwing them up to the prescribed torque. Refit the new cartridge filter being careful to lubricate the O-ring before fitting it. Change the engine oil.

Oil pressure warning light
The vehicle is equipped with a telltale light on the dashboard that lights up when the key is turned to the «ON» position. However, this light should switch off once the engine has been started.
If the light turns on during braking, at idling speed or while turning a corner, it is necessary to check the oil level and the lubrication sys­tem.
Checking the ignition timing
- Remove the plastic cap on the flywheel cover
-Turn the flywheel until the reference mark «T» on
the rotor matches the reference mark on the fly­wheel cover as shown in the figure (TDC). Make sure that the 4V reference point on the camshaft control pulley is aligned with the reference point on the head as shown in the second figure. If the ref­erence is opposite the indicator on the head, turn the crankshaft once more. For the use of this reference mark, remove the spark plug and turn the engine in the direction that is the reverse of the normal direction using a cal­liper spanner applied to the camshaft command pulley casing.

Checks and inspections
This section is dedicated to the checks on the electrical system components.
Immobiliser
The electronic ignition system is controlled by the control unit with the integrated Immobilizer sys­tem. The immobilizer is an anti-theft system that allows the vehicle to be operated only when it is started with coded keys recognised by the control unit. The code is integrated in a transponder in the key block. This allows the driver clear operation without having to do anything other than just turn­ing the key. The Immobilizer system consists of the following components:
- an electronic control unit
- immobilizer aerial
- Master key with incorporated transponder (red key)
- service key with incorporated transponder (black key)
- HV coil
- diagnosis LED The diagnosis LED also works as a theft-deterrent blinker. This function is activated every time the ignition switch is turned to the "OFF" position, or the emergency stop switch is turned to the "OFF" position. It remains activated for 48 hours in order not to affect the battery charge. When the ignition switch is turned to the "ON" position, the theft-de-

terrent blinker function is deactivated. Subse­quently, a flash confirms the switching to the "ON" status. The duration of the flash depends on the programming of the electronic control unit If the LED is off regardless of the position of the ignition­key switch and/or the instrument panel is not initi­ated, check if:
there is battery voltage
fuses 1,7,10 are in working order
there is power to the control unit as specified below:
Remove the connector support bracket shown in the photograph and disconnect the connector from the control unit. Check the following conditions:
With the key switch set to OFF:
if there is battery voltage between ter­minals 6-26 and terminal 6-chassis ground (fixed power supply). If there is no voltage check that fuse 1 and its ca­ble are in working order.
With the key switch in the OFF position:
there is battery voltage between termi­nals 5-26 and terminal 5-frame earth (fixed power supply). If there is no volt­age, check the key switch contacts, that fuse no. 10 and its cable are in working order.

There is continuity between terminals 12-18 with the emergency cut-off switch in the RUN position. If there is no continuity check the contacts of the switch.
If no faults are found, replace the electronic control unit.
After removing the leg shield back plate, remove the electrical connection from the aerial as shown in the picture.
Remove the protective base from the connector.
With the ignition key at ON check there is battery voltage between the Red-White and Black cables

When the ignition system is not encrypted, any key will start the engine but limited to 2000 rpm. The keys can only be recognised if the control unit has been programmed properly. The data storage pro­cedure for a previously not programmed control unit provides for the recognition of the master as the first key to be stored to memory: this becomes particularly important because it is the only key that enables the control unit to be wiped clean and reprogrammed for the memorisation of the service keys. The master and service keys must be used to code the system as follows:
- Insert the Master key, turn it to «ON» and keep this position for two seconds (limit values 1 to 3 seconds).
- Insert the service key and turn it to «ON» for 2 seconds.
- If you have copies of the key, repeat the operation with each key.
- Insert the MASTER key again and turn it to «ON» for 2 seconds. The maximum time to change keys is 10 seconds. A maximum of 7 service keys can be programmed at one time. It is essential to adhere to the times and the procedure. If you do not, start again from the beginning. Once the system has been programmed, the master key transponder is strictly matched with the control unit. With this link established, it is now possible to encode new service keys, in the event of losses, replacements, etc. Each new programming deletes the previous one; to add or delete a key it is therefore necessary to repeat the procedure using all the keys that you intend to keep in use. If a service key becomes uncoded, the efficiency of the high voltage circuit shielding must be thoroughly inspected: In any case it is advisable to use resistive spark plugs.

Diagnostic codes
The Immobilizer system is tested each time the ig­nition key is turned from «OFF» to «ON». During this diagnosis phase a number of control unit sta­tuses can be identified and various light codes displayed. Regardless of the code transmitted, if at the end of the diagnosis the LED remains off permanently, the ignition is enabled. If, however, the LED remains on permanently, it means the ig­nition is inhibited:
1. Previously unused control unit - key inser­ted: a single 2 second flash is displayed, after
which the LED remains off permanently. The keys can be stored to memory, the vehicle can be star­ted but with a limitation imposed on the number of revs.
2. Previously unused control unit - transpond­er absent or cannot be used: the LED is on
permanently. In this condition no operations are possible including the start up of the vehicle.
3. Programmed control unit - the service key in (normal condition of use): a single 0.7-second
flash is displayed, after which the LED remains off steadily. The engine can be started.
4. Programmed control unit - Master key in: a
0.7-sec flash is displayed followed by the LED re­maining off for 2 sec and then by short 0.46-sec flashes, the same number of times as there are keys stored in the memory including the Master key. When the diagnosis has been completed, the
MP3 500 ie SPORT Business LT (2011) Electrical system

LED remains permanently OFF. The engine can be started.
5. Programmed control unit - fault detected: a light code is displayed according to the fault detected, after which the LED remains on steadily. The engine cannot be started. The codes that can be trans­mitted are:
1-flash code
2-flash code
3-flash code
Diagnostic code - 1 flash
A one-flash code indicates a system where the se­rial line is not present or is not detected. Check the Immobilizer aerial wiring and change it if necessa­ry.
Diagnostic code - 2 flashes
A two-flash code shows a system where the con­trol unit does not show the transponder signal. This might depend on the inefficiency of the immobiliser aerial or the transponder. Turn the switch to ON using several keys: if the code is repeated even with the Master key, check the aerial wiring and change it if necessary. If this is not the case, replace the defective key and/or reprogram the control unit. Replace the control unit if the problem continues.
Electrical system MP3 500 ie SPORT Business LT (2011)
ELE SYS - 72
Page 73
Diagnostic code - 3 flashes
A three-flash code indicates a system where the control unit does not recognise the key. Turn the switch to ON using several keys: if the error code is repeated even with the Master key, replace the control unit. If this is not the case, reprogram the decoder.
Battery recharge circuit
The charging circuit consists of three-phase alternator and a permanent magneto flywheel. The generator is directly connected to the voltage regulator. This, in its turn, is connected directly to the ground and the battery positive terminal passing through the 30A protective fuse. The three-phase alternator provides good recharge power and at low revs a good compromise is ach­ieved between generated power and idle stability.
Remote controls check
To check the operation of a solenoid:
1) Check that, given regular conditions, there is no continuity between terminals 87 and 30.
2) Apply a 12V voltage to power terminals 86 and 85 of the solenoid.
3) With the solenoid fed, check that there is con­tinuity between terminals 87 and 30.
4) If these conditions are not met, the solenoid is surely damaged and, therefore, it should be re­placed.
Stator check
Checking the stator windings
WARNING
THIS CHECK-UP CAN BE MADE WITH THE STATOR PROPERLY INSTALLED.
1) Remove the right side panel.
2) Disconnect the connector between stator and regulator with the three yellow cables as shown in the picture.

WARNING
BEFORE CARRYING OUT THE CHECK, MAKE SURE THAT THE BATTERY IS IN GOOD WORK­ING ORDER.
1) Place the vehicle on its centre stand
2) With the battery correctly connected to the circuit, place the multimeter leads between the battery terminals..
3) Turn on the engine, increase the engine rpm and, at the same time, measure the voltage.
Electric characteristic
Voltage ranging between 14.0 and 15.0V at 5000 rpm. Maximum current output check.
- With the engine off and the panel at «ON» with the lights on, allow the battery voltage to stop at 12V.
- Connect ammeter pliers to the 2 recharge positive poles in output from the regulator.
- Start the engine and rev it up to a high engine speed while reading the value on the pincer. With an efficient battery a value must be detected: > 20A

Sealed battery
If the vehicle is provided with a sealed battery, the only maintenance required is the check of its charge and recharging, if necessary. These operations should be carried out before delivering the vehicle, and on a six-month basis while the vehicle is stored in open circuit. Besides upon pre-delivery it is therefore necessary to check the battery charge and recharge it, if re­quired, before storing the vehicle and afterwards every six months.
INSTRUCTIONS FOR THE RENEWAL RECHARGE AFTER OPEN-CIRCUIT STORAGE
1) Voltage check up
Before installing the battery on the vehicle, check the open circuit voltage with a standard tester.
- If voltage exceeds 12.60 V, the battery can be installed without any renewal recharge.
- If voltage is below 12.60 V, a renewal recharge is required as explained in 2).
2) Constant voltage battery charge mode
- Constant voltage charge equal to 14.40 to 14.70V
- Initial charge voltage equal to 0.3 to 0.5 for Nominal capacity
- Charge time: 10 to 12 h recommended Minimum 6 h Maximum 24 h
3) Constant current battery charge mode
- Charge current equal to 1/10 of the battery rated capacity
- Charge time: Maximum 5 h

WARNING
BATTERY ELECTROLYTE IS TOXIC AND IT MAY CAUSE SERIOUS BURNS. IT CONTAINS SUL­PHURIC ACID. AVOID CONTACT WITH YOUR EYES, SKIN AND CLOTHING. IF COMING INTO CONTACT WITH EYES OR SKIN, WASH ABUNDANTLY WITH WATER FOR APPROX. 15 MIN. AND SEEK IMMEDIATE MEDICAL ATTENTION. IN THE EVENT OF ACCIDENTAL INGESTION OF THE LIQUID, IMMEDIATELY DRINK LARGE QUANTITIES OF WATER OR MILK, MAGNESIUM MILK, BATTERED EGG OR VEGETABLE OIL. SEEK IMMEDIATE MEDICAL ATTENTION. BATTERIES PRODUCE EXPLOSIVE GASES; KEEP CLEAR OF NAKED FLAMES, SPARKS OR CIGARETTES; VENTILATE THE AREA WHEN RECHARGING INDOORS. ALWAYS WEAR EYE PROTECTION WHEN WORKING IN THE PROXIMITY OF BATTERIES. KEEP OUT OF REACH OF CHILDREN
1) Battery preparation
Position the battery on a flat surface. Remove the adhesive sheet closing cells and proceed as quick­ly as possible to run the subsequent activation phases.
2) Electrolyte preparation.
Remove the container of the electrolyte from the pack. Remove and preserve cover strips from the container, in fact, the strip will later be used as a closing cover. Note: Do not pierce the sealing of the container or the container itself because inside there is sulphu­ric acid.
3) Procedure for filling the battery with acid.
Position the electrolyte container upside down with the six areas sealed in line with the six battery filler holes. Push the container down with enough force to break the seals. The electrolyte should start to flow inside the battery. Note: Do not tilt the container to prevent the flow of electrolyte from pausing or stopping.
4) Control the flow of electrolyte
Make sure air bubbles are rising from all six filling holes. Leave the container in this position for 20 minutes or more. Note:If there are no air bubbles coming out of the filling holes, lightly tap the bottom of the container two or three times. Do not remove the container from the battery.
MP3 500 ie SPORT Business LT (2011) Electrical system
ELE SYS - 85
Page 86
5) Take out the container.
Make sure all the electrolyte in the battery is drained. Gently tap the bottom of the container if electrolyte remains in the container. Now, gently pull the container out from the battery, only do this when the container is completely empty, and proceed immediately to the next point.
6) Battery closing.
Insert the airtight cover strips into the filling holes. Press horizontally with both hands and make sure that the strip is levelled with the top part of the battery. Note:To do this, do not use sharp objects that could damage the closing strip, use gloves to protect your hands and do not bring your face close to the battery. The filling process is now complete. Do not remove the strip of caps under any circumstances, do not add water or electrolyte. Place the battery down for 1 to 2 hours prior to the charging from the battery.
7) Recharging the new battery
With the above-mentioned procedure, the battery will have gained around 70% - 75% of its total electrical capacity. Before installing the battery on the vehicle, it must be fully charged and then must be recharged.
If the battery is to be installed on the vehicle prior to this pre-charged one, the battery will not be able to exceed 75% charge without jeop­ardising its useful life on vehicle.
The dry charge battery MF like the completely loa­ded YTX, must have a no-load voltage between
