Precautions for Electrical Circuit Service

B649G10000003

When handling the electrical parts or servicing the ABS system, observe the following points for the safety of the system.

Electrical Parts

Connector / Coupler

When connecting a connector, be sure to push it in until a click is felt.

I310G1000001-01

With a lock type coupler, be sure to release the lock when disconnecting, and push it in fully till the lock works when connecting it.

When disconnecting the coupler, be sure to hold the coupler body and do not pull the lead wires.

Inspect each terminal on the connector/couplerfor looseness or bending.

Inspect each terminal for corrosion and contamination. The terminals must be clean andfree of any foreign material which could impede proper terminal contact.

I310G1000002-01

Inspect each lead wire circuit for poor connection by shaking it by hand lightly. If any abnormal condition is found, repair or replace.

I310G1000003-01

When taking measurements at electrical connectors using a tester probe, be sure to insert the probefrom the wire harness side (backside) of the connector/ coupler.

2. Probe

 

 

When connecting meter probe from the terminal side of the coupler (connection from harness side not being possible), use extra care not to force and cause the male terminal to bend or the female terminal to open. Connect the probe as shown to avoid opening of female terminal. Never push in the probe where male terminal is supposed to fit.

Downloaded from www.Manualsbooks.com manuals search

00-3 Precautions:

• Check the male connector for bend and female

• Be careful not to touch the electrical terminals of the

connector for excessive opening. Also check the

Ignitor unit and ABS control unit/HU. The static

coupler for locking (looseness), corrosion, dust,etc.

electricity from your body may damage this part.

Precautions: 00-4

The ABS control unit/HU cannot bedisassembled. Replace the whole unit with a new one.

I649G1000005-01

Battery connection in reverse polarity is strictly prohibited. Such a wrong connection will damage the components of the ABS control unit/HU instantly when reverse power is applied.

I649G1000006-01

Removing any battery terminal of a running engine is strictly prohibited. The moment such removal is made, damaging counter electromotive force will be applied to the Ignition unit and ABS control unit/HU which may result in serious damage.

I310G1000011-01

Before measuring voltage at each terminal, check to make sure that battery voltage is 11 V or higher. Terminal voltage check at low battery voltage will lead to erroneous diagnosis.

I310G1000012-01

Never connect any tester (voltmeter, ohmmeter, or whatever) to the Ignition and ABS control unit/HU when its coupler is disconnected. Otherwise, damage to Ignitor and ABS control unit/HU may result.

Never connect an ohmmeter to the Ignitor and ABS control unit/HU with its coupler connected. If attempted, damage to Ignitor and ABS control unit/HU or sensors may result.

Be sure to use a specifiedvoltmeter/ohmmeter. Otherwise, accurate measurements may notbe obtained and personal injury may result.

Electrical Circuit Inspection Procedure

While there are various methods for electrical circuit inspection, described here is a general method to check for open and short circuit using an ohmmeter and a voltmeter.

Open circuit check

Possible causes for the open circuit are as follows. As the cause can exist in the connector/coupler or terminal, they need to be checked carefully.

Loose connection of connector/coupler

Poor contact of terminal (due to dirt, corrosion or rust, poor contact tension, entry of foreign object etc.)

Wire harness being open.

Poor terminal-to-wire connection.

When checking system circuits including an electronic control unit such as ignitor, ABS control unit/HU, etc., it is important to perform careful check, starting with items which are easier to check.

Downloaded from www.Manualsbooks.com manuals search

00-5 Precautions:

1)Disconnect the negative (–) cable from the battery.

2)Check each connector/coupler at both ends of the circuit being checked for loose connection. Also check for condition of the coupler lock ifequipped.

Since the brake system of this motorcycle is filled with a glycol-based brake fluid by the manufacturer, do not use or mix different types of fluid such as silicone-based and petroleum-based fluid for refilling the system, otherwise serious damage will result.

Do not use any brake fluid taken from old or used or unsealed containers.

Never reuse brake fluid left over from a previous servicing, which has been stored for a long period.

Front Fork Oil

Use fork oil SS8 or an equivalent fork oil.

BREAK-IN Procedures

B649G10101007

During manufacture only the best possible materials are used and all machined parts are finished to a very high standard but it is still necessary to allow the moving parts to “BREAK-IN” before subjecting the engine to maximum stresses. The future performance and reliability of the engine depends on the care and restraint exercised during its early life. The general rules are asfollows.

1)Keep to these break-in engine speed limits:

Speed limits

Initial 800 km: Below 5 500 r/min Up to 1 600 km: Below 8 000 r/min Over 1 600 km: Below 11 000 r/min

2)Upon reaching an odometer reading of 1 600 km (1 000 miles) you can subject the motorcycle to full throttle operation. However, do not exceed 11 000r/ min at any time.
