Toyota RAV4 (XA40) 2013-2018 Service Manual: Center airbag sensor communication stop mode
Description
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 can bus line for disconnection (center airbag sensor assembly branch wire)
- Disconnect the e45 center airbag sensor connector.
- measure the resistance of the wire harness side connector.
Standard resistance 
- Check wire harness (center airbag sensor assembly - battery and body ground)
- Disconnect the e45 center airbag sensor connector.
- Measure the resistance of the wire harness side connector.
Standard resistance 
- Measure the voltage of the wire harness side connector.

Downhill assist control system
The downhill assist control
system helps to prevent
excessive speed on steep
downhill slopes.
The system will operate
when the vehicle is traveling
under 15 mph (25 km/h) with
the accelerator and brake
pedals released.
WARNING

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
