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.

(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.
