Inspection procedure

NOTICE:

• Turn the ignition switch OFF before measuring the resistances of the CAN main wire and the CAN branch wire.

• After the ignition switch is turned off, check that the key reminder warning system and light reminder warning system are not in operation.

Before measuring the resistance, leave the vehicle as is for at least 1 minute and do not operate the ignition switch, any other switches or the doors. If doors need to be opened in order to check connectors, open the doors and leave them open. HINT:

Operating the ignition switch, any switches or any doors triggers related ECU and sensor communication with the CAN, which causes resistance variation.

When the measured value is 132 Q or higher and a CAN communication system diagnostic trouble code is output, there may be a fault besides disconnection of the DLC3 branch wire. For that reason, troubleshooting should be performed again from "HOW TO PROCEED WITH TROUBLESHOOTING" (See page CA-9) after repairing the trouble area.

REPAIR OR REPLACE CAN BRANCH WIRE CONNECTED TO DLC3 (CAN-H, CAN-L)
