Toyota RAV4 (XA40) 2013-2018 Service Manual: Parts location
System diagram
Hint:
- The abs and traction actuator (skid control ecu) detects and stores steering sensor and yaw rate sensor dtcs and performs dtc communication by receiving information from the steering sensor and yaw rate sensor.
- The ecm uses the can communication system to perform dtc communication instead of the conventional communication line (sil).
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 rem ...

Description
The center airbag sensor consists of the airbag sensor, the safing sensor,
the drive circuit, the diagnosis
circuit and the ignition control.
If the center airbag sensor receives signals from the airbag sensor, it
determines whether or not the srs
should be activated.

Terminals of ecu
Check power steering ecu
Hint:
Measurements cannot be performed on the c connector
side of the power steering ecu.
Measure the voltage and resistance of the
connectors.
If the result is not as specified, the ecu may have a
malfunction. ...
System voltage
Description
The battery supplies electricity to the ecm even when the ignition switch is
in the off position. This
power allows the ecm to store data such as dtc history, freeze frame data and
fuel trim values. If the
battery voltage falls below a minimum level, the memory is cleared and ...
