CAN Communication Line Resistance Inspection

In this model, resistors for CAN communication line are built in the ECU [A] and meter unit.

Refer to the Meter Unit Inspection in the Electrical System chapter for the resistor in the meter unit.
Turn the ignition switch to OFF.
Remove: ECU (see ECU Removal)

CAN Communication Line Resistance Inspection

Connect a digital meter [A] to the ECU connector (black) [B].
Measure the resistance of the CAN communication line resistor.

CAN Communication Line Resistance (at ECU Connector)

Connections: Terminal 27 ←→ Terminal 28

Standard: 123 125 Ω

CAN Communication Line Resistance Inspection

If the reading is out of the range, replace the ECU (see ECU Removal/Installation).

If the reading is within the range, resistor of the ECU for CAN communication line is normal.

Check the wiring for continuity of the CAN communication line (see wiring diagram in this section).

Special Tool - Hand Tester: 57001-1394

If the wiring is open, repair or replace the main harness.

Balance Inspection
Remove the front and rear wheels (see Front/Rear Wheel Removal). Support the wheel so that it can be spun freely. Spin the wheel lightly, and mark [A] the wheel at the top when the wheel stops. Repeat this procedure several times. If the wheel stops of its own accord in various positi ...

Water Temperature Sensor Inspection
Remove the water temperature sensor (see Water Temperature Sensor Removal/Installation in the Fuel System (DFI) chapter). Suspend the sensor [A] in a container of coolant so that the temperature-sensing projection [C] is submerged. Suspend an accurate thermometer [B] with temperature ...

Swingarm Installation
Visually inspect the chain guide [A]. Replace the chain guide if it shows any signs of abnormal wear or damage. Apply a non-permanent locking agent to the threads of the chain guide bolt [B]. Apply plenty of grease to the lip of the oil seals [A]. Be sure to install the oil seals ...
