Toyota RAV4 (XA40) 2013-2018 Service Manual: Can communication system
Precaution
- Precaution
- Turn the ignition switch off before measuring the
resistance 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.
- Steering system handling precautions
- Care must be taken when replacing parts. Incorrect
replacement could affect the performance of the
steering system and result in hazards when driving.
- Srs airbag system handling precautions
- This vehicle is equipped with an srs
(supplemental restraint system) such as the driver
airbag and front passenger airbag. Failure to carry
out service operations in the correct sequence could
cause unexpected srs deployment during
servicing and may lead to a serious accident. Before
servicing (including installation/removal, inspection
and replacement of parts), be sure to read the
precautionary notice for the supplemental restraint
system (see page rs-1).
- Bus line repair

- After repairing the bus line with solder, wrap the
repaired part with vinyl tape (see page in-37).
Notice:
- The canl bus line and canh bus line must
be installed together.
- When installing, twist them together.
- Can bus lines are likely to be influenced by
noise if the bus lines are not twist together.
- The difference in length between the canl
bus line and canh bus line should be less
than 100 mm (3.937 In.).
- Leave approximately 80 mm (3.150 In.) Loose
in the twisted wires around the connectors.

- Do not use bypass wiring between the connectors.
Notice:
The feature of the twisted wire harness will be
lost if bypass wiring is used.
- Connector handling

- When inserting tester probes into a connector, insert
them from the rear of the connector.

- Use a repair wire to check the connector if it is
impossible to check resistance from the rear of the
connector.
