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.
