GENINFOFEATURES

GENERAL INFORMATIONFEATURESOUTLINEThe main function of a fuel supply system is to provide fuel to the combustion chamber at the opti-mum air-fuel ratio in accordance with the engine operating conditions and the atmospheric tempera-ture.In the conventional carburetor system, the air-fuel ratio of the mixture that is supplied to the com-bustion chamber is created by the volume of the intake air and the fuel that is metered by the jet thatis used in the respective carburetor.Despite the same volume of intake air, the fuel volume requirement varies by the engine operatingconditions, such as acceleration, deceleration, or operating under a heavy load. Carburetors thatmeter the fuel through the use of jets have been provided with various auxiliary devices, so that anoptimum air-fuel ratio can be achieved to accommodate the constant changes in the operating con-ditions of the engine.As the requirements for the engine to deliver more performance and cleaner exhaust gasesincrease, it becomes necessary to control the air-fuel ratio in a more precise and finely tuned man-ner. To accommodate this need, this model has adopted an electronically controlled fuel injection(FI) system, in place of the conventional carburetor system. This system can achieve an optimumair-fuel ratio required by the engine at all times by using a microprocessor that regulates the fuelinjection volume according to the engine operating conditions detected by various sensors.The adoption of the FI system has resulted in a highly precise fuel supply, improved engineresponse, better fuel economy, and reduced exhaust emissions. Furthermore, the air induction sys-tem (AI system) has been placed under computer control together with the FI system in order torealize cleaner exhaust gases.

GENINFOFEATURES

FI SYSTEMThe fuel pump delivers fuel to the injector via the fuel filter. The fuel pump maintains the fuel pres-sure that is applied to the injector at only 324 kPa (3.24 kg/cm2, 46.08 psi). Accordingly, when theenergizing signal from the ECU energizes the injector, the fuel passage opens, causing the fuel tobe injected into the intake manifold only during the time the passage remains open. Therefore, thelonger the length of time the injector is energized (injection duration), the greater the volume of fuelthat is supplied. Conversely, the shorter the length of time the injector is energized (injection dura-tion), the lesser the volume of fuel that is supplied.

The injection duration and the injection timing are controlled by the ECU. Signals that are input fromthe throttle position sensor, crankshaft position sensor, intake air pressure sensor, intake air tem-perature sensor, coolant temperature sensor, and O2 sensor enable the ECU to determine theinjection duration. The injection timing is determined through the signals from the crankshaft posi-tion sensor and the cylinder identification sensor. As a result, the volume of fuel that is required bythe engine can be supplied at all times in accordance with the driving conditions.

* Table of self-diagnostic fault code numbers displayed on meter

• How to erase the self-diagnostic fault code from memory:If the ECU detects a normal signal upon the completion of the repair of the malfunction, the self-diagnostic fault code disappears from the meter and is replaced by the normal clock display. How-ever, the self-diagnostic fault code of the previous malfunction remains in the ECU memory aspart of the malfunction history. To erase the self-diagnostic fault code from the malfunction history,the operation for diagnostic code 62 must be performed in the diagnosis mode.

SUBSTITUTE CHARACTERISTICS OPERATION CONTROL (FAIL-SAFE ACTION)If the ECU detects an abnormal signal from a sensor while the motorcycle is being driven, the ECUilluminates the engine trouble warning light and provides the engine with substitute characteristicoperation instructions that are appropriate for the type of the malfunction.When an abnormal signal is received from a sensor, the ECU processes the specified values thatare programmed for every sensor, in order to provide the engine with substitute characteristicsoperation instructions that enable the engine to continue to operate (or to stop its operation,depending on circumstances).The ECU takes fail-safe actions in two ways: one in which the sensor output is set to a prescribedvalue, and the other in which the ECU directly operates an actuator. Details on the fail-safe actionsare given in the table below.

Sensor operation data display verification table

NOTE:• Check the intake air temperature and coolant temperature as close as possible to the area in

which the respective sensor is mounted.• If it is not possible to check the intake temperature, use the ambient temperature as reference

(use the compared values for reference).

Diag code Item Description of actionData displayed on meter

(reference value)

01Throttle angle Displays the throttle angle.

• Check with throttle fully closed.• Check with throttle fully open.

0 ~ 125 degrees• Fully closed position (15 ~ 17)• Fully open position (97 ~ 100)

03

Pressure difference (atmospheric pres-sure - intake air pres-sure)

Displays the pressure difference (atmospheric pressure - intake air pressure).Engine stop switch is on.* Generate the pressure difference by cranking the engine

with the starter, without actually starting the engine.

Before cranking: Atmospheric pressure (standard pressure is 760 mmHg)After cranking: Value is lower than the atmospheric pressure

05Intake air tempera-ture

Displays the intake air temperature.* Check the temperature in the air cleaner case.

Compare it to the value dis-played on the meter.

06Coolant temperature Displays the coolant temperature.

* Check the temperature of the coolant.Compare it to the value dis-played on the meter.

07Vehicle speed pulse Displays the accumulation of the vehicle pulses that are gen-

erated when the tire is spun.(0 ~ 999; resets to 0 after 999)OK if the numbers appear on the meter.

08Lean angle cut-off switch

Displays the lean angle cut-off switch values. Upright: 0.4 ~ 1.4 VOverturned: 3.8 ~ 4.2 V

09Fuel system voltage (battery voltage)

Displays the fuel system voltage (battery voltage).Engine stop switch is on.

0 ~ 18.7 VNormally, approximately 12.0 V

20Sidestand switch Displays that the switch is ON or OFF. (When the gear is in a

position other than neutral.)Stand retracted: ONStand extended: OFF

21Neutral switch Displays that the switch is ON or OFF. Neutral: ON

In gear: OFF

60

E2PROM fault code display

• Transmits the abnormal portion of the data in the E2PROM that has been detected as a self-diagnostic fault code 44.

• If multiple malfunctions have been detected, different codes are displayed at 2-second intervals, and this process is repeated.

(01 ~ 04) Displays the cylinder number.(00) Displays when there is no malfunction.

61

Malfunction history code display

• Displays the codes of the history of the self-diagnosis mal-functions (i.e., a code of a malfunction that occurred once and which has been corrected).

• If multiple malfunctions have been detected, different codes are displayed at 2-second intervals, and this process is repeated.

11 ~ 50(00) Displays when there is no malfunction.

62

Malfunction history code erasure

• Displays the total number of codes that are being detected through self diagnosis and the fault codes in the past his-tory.

• Erases only the history codes when the engine stop switch is turned from OFF to ON. If the engine stop switch is ON, turn it OFF once, and then turn it back ON.

00 ~ 21(00) Displays when there is no malfunction.

70 Control number • Displays the program control number. 00 ~ 255

Troubleshooting detailsTroubleshooting the self-diagnostic fault code

Code No. 19 Symptom A break or disconnection of the black/red lead of the ECU is detected.Used diagnostic code No. 20 (sidestand switch)Inspection operation item and probable cause Operation item and countermeasure Reinstatement

methodDefective sidestand switch Replace if defective.

Refer to “CHECKING THE SWITCHES” in chapter 8. (Manual No.: 5JW1-AE1)

If the transmission is in gear, it is rein-stated by retracting the sidestand.If the transmission is in neutral, it is reinstated by reconnecting the wiring.

Open circuit in wiring harness or sub lead. Repair or replace if there is an open circuit.(Between ECU and black/red lead)

Connected state of connectorInspect the coupler for any pins that may have pulled out.Check the locking condition of the coupler.

If there is a malfunction, repair it and connect it securely.Main wiring harness ECU coupler
