Toyota RAV4 (XA40) 2013-2018 Service Manual: Receiver error
Description
Wiring diagram
Inspection procedure
Notice:
It is necessary to register an id code after replacing the tire pressure warning valve abd transmitter and/or the tire pressure warning ecu (see page tw-9).
Hint:
Set the tire pressure to the specified value.
Standard pressure: 220 kpa (2.2 Kgf/cm2, 32 psi)
- Check tire pressure warning ecu
- Measure the voltage of the connector.
Standard voltage 
- Check wire harness (ecu - receiver)
- Disconnect the e56 ecu connector.
- Disconnect the l20 receiver connector.
- Measure the resistance of the wire harness side connectors.
Standard resistance 
- Replace tire pressure warning antenna and receiver
- Check dtc
- Check for dtc (see page tw-20).
Ok: dtc is not output.
Hint:
- It is necessary to register an id when replacing the tire pressure warning ecu (see page tw-9).
- Read id on the data list before removing the tire pressure warning ecu. Register the id in the new tire pressure warning ecu.
End
- Check wire harness (ecu - receiver)
- Disconnect the e56 ecu connector.
- Disconnect the l22 receiver connector.
- Measure the resistance of the wire harness side connectors.

Vehicle speed signal error (test mode dtc)
Description
The tire pressure warning ecu receives a speed signal from the combination
meter. This dtc is stored
upon entering test mode, and cleared when a vehicle speed signal of 12 mph (20 ...
Other materials:
Air-fuel ratio (a/f) and heated oxygen (ho2) sensor
heater monitors (front a/f and rear ho2 sensor type)
Preconditions
The monitor will not run unless:
The mil is off.
Drive pattern
Connect the intelligent tester to the dlc3.
Turn the ignition switch on.
Turn the tester on.
Clear dtcs (if set) (see page es-35).
Start the engine.
Allow the engine to idle for 10 minute ...
Parking Support Brake function
(static objects)
If the sensors detect a static object, such as a wall, in the
traveling direction of the vehicle and the system determines
that a collision may occur due to the vehicle suddenly moving
forward due to an accidental accelerator pedal operation, the
vehicle moving the unintended direction due to the wr ...

Components
Removal
Remove front tire
Remove rear tire
Remove tire pressure warning valve subassembly
Remove the valve core and cap, and release air
from the tire.
After ensuring that air is sufficiently released,
remove the nut and washer that are used to fix the
tire pres ...
