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.

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 ...

Problem symptoms table
Hint:
Use the table below to help determine the cause of the
problem symptom. The potential causes of the symptoms are
listed in order of probability in the "suspected area" column of
the table. Check each symptom by checking the suspected
areas in the order th ...
Communication
Description
When a key is inserted into the ignition key cylinder but no communication
occurs between the key and
transponder key ecu, dtc b2796 is output. When a key is inserted into the
ignition key cylinder but a
communication error occurs between the key and transponder key ecu, dtc b ...
Registering ID codes
(vehicles with tire pressure
warning system)
Every tire pressure warning
valve and transmitter has a
unique ID code. When replacing
a tire pressure warning valve
and transmitter, it is necessary
to register the ID code.
When registering the ID codes,
perform the following procedure.
â– Registering procedure (with
7-inch display)
1. Park the ...
