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

Assist map number un-writing
Description
The power steering ecu outputs this dtc when it determines that the assist
map is not written in the
ecu.
Hint:
The assist map data is written in the power steering ecu to control assisting
power.
The assist map has 3 types. Select an assist map according to the vehicle
...
Compressor lock sensor circuit
Description
This sensor sends 1 pulse per engine revolution to the air conditioning
amplifier. If the ratio of the
compressor speed divided by the engine speed is smaller than a predetermined
value, the air conditioning
amplifier turns the compressor off, and the indicator blinks at appro ...
Test mode procedure
Test mode check
Hint:
When entering the test mode, the tire pressure
warning ecu sets all the test dtcs first. After
completing the test mode for each inspection item, the
dtcs that are determined normal by the tire pressure
warning ecu will be erased.
The dtcs for other inspec ...
