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.

Swingarm Bearing, Sleeve Inspection
NOTICE Do not remove the bearings for inspection. Removal may damage them. Inspect the needle bearings [A] and ball bearing installed in the swingarm. The rollers and ball in a bearing normally wear very little, and wear is difficult to measure. Instead of measuring, visually inspec ...

ECU Power Supply Inspection
Remove the upper air cleaner housing (see Air Cleaner Element Replacement in the Periodic Maintenance chapter). Visually inspect the ECU connectors. If the connector is clogged with mud or dust, blow it off with compressed air. Remove the ECU (see ECU Removal). Visually inspect the ...
