REGISTRATION
PROCEDURE
1. BEFORE REGISTRATION
NOTICE:
The transmitter ID is written on the tire pressure warning valve and transmitter. It is not 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.
(a) In case of tire pressure warning ECU and receiver replacement:
(1) Read the registered transmitter IDs that are stored in the old ECU using the Techstream and write them down.
(2) If reading the stored transmitter IDs is impossible due to malfunctions of components such as the tire pressure warning ECU and receiver, remove the tires from the wheels and check the IDs located on the tire pressure warning valve and transmitters.
(b) In case of tire pressure warning valve and transmitter replacement:
(1) Take a note of the 7-digit number (transmitter ID) written on the tire pressure warning valve and transmitter.

2. REGISTER TRANSMITTER ID (USING TECHSTREAM)
HINT:
(a) Set the tire pressure to the specified value (See page
).
(b) Turn the ignition switch off.
(c) Connect the Techstream to the DLC3.
(d) Turn the ignition switch to ON and the Techstream on.
(e) Enter the following menus: Chassis / Tire Pressure Monitor / Utility / ID Registration.
(f) Perform the procedure displayed on the Techstream.
3. CONFIRMATION OF TRANSMITTER ID REGISTRATION
NOTICE:
(a) Enter the following menus: Chassis / Tire Pressure Monitor / Data List.

---|---|---|---|
ID 1 Tire Inflation Pressure |
ID1 tire inflation pressure/ min.: Absolute pressure (abs) / 0 kPa (0 kgf/cm2, 0 psi), Relative pressure (Gauge) / 0 kPa (0 kgf/cm2, 0 psi) max.: Absolute pressure (abs) / 480 kPa (4.9 kgf/cm2, 70 psi), Relative pressure (Gauge) / 380 kPa (3.9 kgf/ cm2, 55 psi) |
Actual tire inflation pressure |
If N/A is displayed, data has not been received.*1 |
ID 2 Tire Inflation Pressure |
ID2 tire inflation pressure/ min.: Absolute pressure (abs) / 0 kPa (0 kgf/cm2, 0 psi), Relative pressure (Gauge) / 0 kPa (0 kgf/cm2, 0 psi) max.: Absolute pressure (abs) / 480 kPa (4.9 kgf/cm2, 70 psi), Relative pressure (Gauge) / 380 kPa (3.9 kgf/ cm2, 55 psi) |
Actual tire inflation pressure |
If N/A is displayed, data has not been received.*1 |
ID 3 Tire Inflation Pressure |
ID3 tire inflation pressure/ min.: Absolute pressure (abs) / 0 kPa (0 kgf/cm2, 0 psi), Relative pressure (Gauge) / 0 kPa (0 kgf/cm2, 0 psi) max.: Absolute pressure (abs) / 480 kPa (4.9 kgf/cm2, 70 psi), Relative pressure (Gauge) / 380 kPa (3.9 kgf/ cm2, 55 psi) |
Actual tire inflation pressure |
If N/A is displayed, data has not been received.*1 |
ID 4 Tire Inflation Pressure |
ID4 tire inflation pressure/ min.: Absolute pressure (abs) / 0 kPa (0 kgf/cm2, 0 psi), Relative pressure (Gauge) / 0 kPa (0 kgf/cm2, 0 psi) max.: Absolute pressure (abs) / 480 kPa (4.9 kgf/cm2, 70 psi), Relative pressure (Gauge) / 380 kPa (3.9 kgf/ cm2, 55 psi) |
Actual tire inflation pressure |
If N/A is displayed, data has not been received.*1 |
HINT:
*1: It may take a few minutes until the values are displayed. If the values are not displayed after a few minutes, perform troubleshooting according to the inspection procedure for DTCs C2121/21 to C2124/24.
(b) Reduce the tire inflation pressure of each tire 40 kPa (0.4 kgf/cm2, 5.8 psi) or more within 30 seconds, and check that the "ID Tire Inflation Pressure" data is updated and that the actual tire inflation pressures are displayed.
(c) After confirming that all of the tire inflation pressure values (except the compact spare tire) have been updated, adjust the tire inflation pressure to the specified value, press the tire pressure warning reset switch and perform initialization.
4. TIRE POSITION IDENTIFICATION (USING TECHSTREAM) (w/ Tire Inflation Pressure Display Function)
(a) Set the tire pressure to the specified value (See page
).
(b) Turn the ignition switch off.
(c) Connect the Techstream to the DLC3.
(d) Turn the ignition switch to ON and the Techstream on.
(e) Enter the following menus: Chassis / Tire Pressure Monitor / Data List.
(f) Rapidly reduce the tire pressure for each wheel at least 40 kPa (0.4 kgf/cm 2, 5.8 psi) within 30 seconds.
NOTICE:
(g) Read the "ID Tire Inflation Pressure" value and identify the tire with reduced pressure, and record the corresponding tire pressure warning valve and transmitter (ID1 to ID4).
(h) Repeat for each tire.
(i) Set the tire pressure to the specified value (See page
).
(j) Enter the following menus: Chassis / Tire Pressure Monitor / Utility / Tire Position Write.
(k) Perform the procedure displayed on the Techstream.
5. TIRE POSITION IDENTIFICATION (NOT USING TECHSTREAM) (w/ Tire Inflation Pressure Display Function)
(a) Set the tire pressure to the specified value (See page
).
(b) The tire position can be automatically identified using any of the following 2 methods:
(1) Perform initialization to clear the existing tire position information, then drive the vehicle at 37 km/h (23 mph) or more for 10 minutes or more until each tire position is automatically identified.
(2) Without performing initialization, drive the vehicle as normal until each tire position is automatically updated.

1. DATA LIST
HINT:
Using the Techstream to read the Data List allows the values or states of switches,
sensors, actuators and other items to be read without removing any parts. This non-intrusive
inspection can be very useful because intermittent conditions or signals ...
Speaker Circuit
DESCRIPTION
If there is a short in a speaker circuit, the stereo component amplifier assembly*1
or navigation receiver assembly*2 detects it and stops output to the speakers.
Thus sound cannot be heard from the speakers even if there is no malfunction
in the stereo component amplifier assembly ...
