Kawasaki Ninja Service Manual / Fuel System (DFI) / CAN Communication Line

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.

KIBS Hydraulic Unit Communication Error (Service Code 1b, KIBS Equipped Models)
KIBS Hydraulic Unit Communication Line Inspection When the data (for status of KIBS hydraulic unit) is not sent from the KIBS hydraulic unit to the meter unit and ECU, the service code 1b is displayed. The data is sent through the CAN communication line. The service code 1b is detected with the ...

Starter Clutch Inspection
Remove: Torque Limiter Cover (see Torque limiter Removal) Turn the torque limiter [A] by hand. The torque limiter should turn forward freely [B], but should not turn backward. If the starter clutch does not operate as it should or if it makes noise, go to the next step. Disassem ...

Precautions
There are a number of important precautions that are musts when servicing electrical systems. Learn and observe all the rules below. Do not reverse the battery cable connections. This will burn out the diodes on the electrical parts. Always check battery condition before condemning other ...
