Toyota Venza: Registration
REGISTRATION
PROCEDURE
1. DESCRIPTION OF CODE REGISTRATION
It is necessary to register the transmitter IDs in the tire pressure warning
ECU when replacing a tire pressure warning valve and transmitter and/or a tire pressure
warning ECU.
Prepare all transmitter ID data before starting registration.
(a) Before registration
(1) When replacing the tire pressure warning ECU:
- Read the registered transmitter IDs that are stored in the old ECU using
the Techstream and note them down.
- 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 valve and transmitters (See page
).
(2) When replacing a tire pressure warning valve and transmitter:
- Make a note of the 7-digit number (transmitter ID) written on the tire
pressure warning valve and transmitter.
NOTICE:
- The transmitter ID is written on the tire pressure warning valve
and transmitter. It will not be possible to read the transmitter
ID after installing the tire onto the wheel. Therefore, make a note
of the transmitter ID before installing the tire.
- When one tire pressure warning valve and transmitter is replaced,
the transmitter IDs for all the tire pressure warning valve and
transmitters must be re-registered. Before registering the transmitter
ID of the new tire pressure warning valve and transmitter, check
the Data List and record the all of the transmitter IDs that are
already registered.
2. REGISTER TRANSMITTER ID (Using Techstream)
(a) Set all tire pressures to the specified value(s) (See page
).
(b) Turn the ignition switch off.
(c) Connect the Techstream to the DLC3.
(d) Turn the ignition switch to ON.
(e) Turn the Techstream on.
(f) Enter the following menus: Chassis / Tire Pressure Monitor / Utility / ID
Registration.
(g) Follow the ID Registration steps displayed the Techstream screen.
(h) Confirmation of transmitter ID registration.
(1) Enter the following menus: Chassis / Tire Pressure Monitor / Data List.
(2) Read the "ID Tire Inflation Pressure" values.
(3) Confirm that the tire pressure data of all tires are displayed on the Techstream.
NOTICE:
- It may takes about 2 or 3 minutes to display the updated tire pressure
data. If the values are not displayed after a few minutes, perform troubleshooting
according to the inspection procedure for DTCs C2121/21 to C2124/24 (See
page ).
- If the IDs have not been registered, DTC C2171/71 is set in the tire
pressure warning ECU after 3 minutes or more.
- If normal pressure values are displayed, the IDs have been registered
correctly.
- If the tire pressure values are not displayed after a few minutes, the
IDs may be incorrect or the system may have a malfunction.
- After all IDs are registered, DTC C2126/26 (Transmitter ID not Received)
is set in the tire pressure warning ECU and the tire pressure warning light
blinks for 1 minute and then comes on. When the tire pressure warning ECU
successfully receives signals from all the transmitters whose IDs are stored
in the ECU, DTC C2126/26 is cleared and the tire pressure warning light
goes off.
