DESCRIPTION The IDs of each tire pressure warning valve and transmitter are registered to the tire pressure warning ECU and receiver.
When the ECU detects that a transmitter ID code is not registered in the ECU, this DTC is stored.

Note | C2171/71 |
Transmitter ID not Registered |
Transmitter ID code is not registered. (When an ID code is unregistered for 3 minutes or more) |
Tire pressure warning ECU and receiver |
- | CAUTION / NOTICE / HINT
NOTICE:
- When replacing the tire pressure warning ECU and receiver, read the
transmitter IDs stored in the old ECU using the Techstream and write
them down before removal.
- It is necessary to perform initialization after registration
of the transmitter IDs into the tire pressure warning ECU and receiver if the ECU has been replaced.
PROCEDURE
1. | CONFIRM REGISTRATION CONDITION (REGISTERED ID CODES) |
(a) Turn the ignition switch off. (b) Connect the Techstream to the DLC3.
(c) Turn the ignition switch to ON. (d) Turn the Techstream on.
(e) Enter the following menus: Chassis / Tire Pressure Monitor / Data List.
(f) Check the values by referring to the table below. 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.* |
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.* |
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.* |
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.* |
HINT:
- *: It may take a few minutes until the values are displayed.
For this vehicle, data reception from the tire pressure
warning valve and transmitter may worsen while displaying the Data List
and it may takes longer than usual to receive data.
If
data reception worsens while displaying the Data List, rapidly decrease
the tire pressure by 20 to 30 kPa (this increases the valve
transmission frequency).
- The wheel position cannot be determined from ID1 through ID4 on the Data List.
- When an "ID Tire Inflation Pressure" value has not changed, reset the
tire pressure to the appropriate specified value and rotate the tire 90
to 270 degrees. Then rapidly release the tire pressure and recheck the
value.
