Toyota RAV4 (XA40) 2013-2018 Service Manual: Open in can main wire
Description
There may be an open circuit in the can main wire and / or the dlc3 branch
wire when the resistance
between terminals 6 (canh) and 14 (canl) of the dlc3 is 69 ù or more.

Wiring diagram

Inspection procedure
Notice:
- Turn the ignition switch off before measuring the resistances of the
main wire and the 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 for at least 1
minute and do not operate the
ignition switch, any switches or 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.
- Check dlc3

- Measure the resistance of the dlc3.
Standard resistance 
Notice:
When the measured value is 132 ù or more 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-8) after repairing the trouble area.

- Check can main wire for disconnection (no. 2 Junction connector - ecm)

- Disconnect the e68 no. 2 Junction connector.
- Measure the resistance of the wire harness side
connector.
