Toyota RAV4 (XA40) 2013-2018 Service Manual: Terminals of ecu (2005/11-2006/01)
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.
- Junction connector
- No. 1 Junction connector
-
No. 2 Junction connector
- No. 3 Junction connector
- No. 4 Junction connector
Hint:

Ecm communication circuit malfunction
Description
The circuit is used to send trc and vsc control information from the skid
control ecu to the ecm, and
engine control information from the ecm to the skid control ecu.
