Toyota RAV4 Service Manual: Registration
- In case of tire pressure warning ecu
replacement
- Read id stored in the old ecu using the intelligent
tester.
- In case of tire pressure warning valve and
transmitter and/or tire pressure warning
ecu replacement
- Read the id written on the tire pressure monitor
valve.
- Register transmitter id

Notice:
It is necessary to register the transmitter id in the
tire pressure warning ecu when replacing the tire
pressure warning valve and transmitter and/or tire
pressure warning ecu.
- Prepare all of the transmitter id data before starting
registration.
Hint:
- Read the registered transmitter ids that are
stored in the ecu using the intelligent tester and
make a note of them.
- If reading stored transmitter ids is impossible
due to malfunctions of components such as the
tire pressure warning antenna and receiver,
remove the tires from the wheels and check the
ids located on the tire pressure warning valves
and transmitters (see page tw-60).
- When replacing the tire pressure warning valves
and transmitters, make a note of the ids written
on the tire pressure warning valves and
transmitters.

- Connect the intelligent tester (with can vim) to the
dlc3.
- Turn the ignition switch on.
- *1: Read and write down the id (id1 to id5) by
using the data list.

- *2: Select regist tire set following the
intelligent tester screen (utility - regist tire
set).
- *3: Select the registration mode "main".

- Input the id (id1 to id5) using the intelligent tester
and transmit it to the tire pressure warning ecu.
- Set the id transmission condition to "id registration
is complete".

Hint:
- The previously registered ids will be deleted
from the memory when the registration is
completed.
- If the operations of *1 to *3 are not completed
within 5 minutes, the mode will return to normal
operation mode.
- Confirmation of transmitter id
registration
- Set the tire pressure of all wheels (including the
spare tire) to the specified value.
Standard pressure:
220 kpa (2.2 Kgf/cm2, 32 psi)
- Connect the intelligent tester (with can vim ) to the
dlc3.
- Turn the ignition switch on.
- Select "signal check" mode on the intelligent
tester (with can vim ) (see page tw-12).
- Confirm that the transmitter ids and tire pressure
data for all the tires are displayed on the intelligent
tester screen.
Notice:
- It may take up to 1 minute to update the tire
pressure data.
- If the ids have not been registered, dtc
c2171/71 is set in the tire pressure warning
ecu after approximately 60 minutes.
Hint:
Use these procedures to troubleshoot the tire pressure
warning system.
*: Use the intelligent tester.

If you think
something is wrong
If you notice any of the following symptoms, your vehicle probably
needs adjustment or repair. Contact your toyota dealer as
soon as possible.

Check for intermittent problems
Hint:
Inspect the vehicle's ecm using check mode. Intermittent
problems are easier to detect with the intelligent tester when
the ecm is in check mode. In check mode, the ecm uses 1
trip detection logic, which is more sensitive to malfunctions
than normal mode (default), which uses 2 trip detec ...
