DTC |
C2171/71 |
Transmitter ID not Registered |
DESCRIPTION
The transmitter IDs of each tire pressure warning valve and transmitter are registered to the tire pressure warning ECU.
When the IDs have never been registered, a DTC is output.
|
DTC No. |
DTC Detection Condition |
Trouble Area |

C2171/71 |
Transmitter ID is not registered. (When a transmitter ID is unregistered for 3 minutes or more) |
Tire pressure warning ECU |
CAUTION / NOTICE / HINT
NOTICE:
- When replacing the tire pressure warning ECU, read the transmitter IDs stored in the old ECU using the Techstream and note them down before removal.
-
It is necessary to perform initialization (See page
![2016 - 2020 MY Sienna [12/2015 - ]; TIRE PRESSURE MONITORING: TIRE PRESSURE WARNING SYSTEM: INITIALIZATION](/t3Portal/stylegraphics/info.gif)
) after registration (See page
) of the transmitter IDs into the tire pressure warning ECU after the ECU has been replaced.
PROCEDURE
|
1. |
CONFIRM REGISTRATION CONDITION (REGISTERED TRANSMITTER IDS) |
(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.

ID1 Tire Inflation Pressure |
ID1 tire inflation pressure / min.: Absolute pressure / 100 kPa (1 kgf/cm2, 14 psi), Relative pressure / 0 kPa (0 kgf/cm2, 0 psi) max.: Absolute pressure / 449.35 kPa (4.6 kgf/cm2, 65 psi), Relative pressure / 349.35 kPa (3.6 kgf/cm2, 51 psi) |
Actual tire inflation pressure |
If 100 kPa (1 kgf/cm2, 14 psi) is displayed for absolute pressure or 0 kPa (0 kgf/cm2, 0 psi) is displayed for relative pressure, data has not been received.* |
|
ID2 Tire Inflation Pressure |
ID2 tire inflation pressure / min.: Absolute pressure / 100 kPa (1 kgf/cm2, 14 psi), Relative pressure / 0 kPa (0 kgf/cm2, 0 psi) max.: Absolute pressure / 449.35 kPa (4.6 kgf/cm2, 65 psi), Relative pressure / 349.35 kPa (3.6 kgf/cm2, 51 psi) |
Actual tire inflation pressure |
If 100 kPa (1 kgf/cm2, 14 psi) is displayed for absolute pressure or 0 kPa (0 kgf/cm2, 0 psi) is displayed for relative pressure, data has not been received.* |
|
ID3 Tire Inflation Pressure |
ID3 tire inflation pressure / min.: Absolute pressure / 100 kPa (1 kgf/cm2, 14 psi), Relative pressure / 0 kPa (0 kgf/cm2, 0 psi) max.: Absolute pressure / 449.35 kPa (4.6 kgf/cm2, 65 psi), Relative pressure / 349.35 kPa (3.6 kgf/cm2, 51 psi) |
Actual tire inflation pressure |
If 100 kPa (1 kgf/cm2, 14 psi) is displayed for absolute pressure or 0 kPa (0 kgf/cm2, 0 psi) is displayed for relative pressure, data has not been received.* |
|
ID4 Tire Inflation Pressure |
ID4 tire inflation pressure / min.: Absolute pressure / 100 kPa (1 kgf/cm2, 14 psi), Relative pressure / 0 kPa (0 kgf/cm2, 0 psi) max.: Absolute pressure / 449.35 kPa (4.6 kgf/cm2, 65 psi), Relative pressure / 349.35 kPa (3.6 kgf/cm2, 51 psi) |
Actual tire inflation pressure |
If 100 kPa (1 kgf/cm2, 14 psi) is displayed for absolute pressure or 0 kPa (0 kgf/cm2, 0 psi) is displayed for relative pressure, data has not been received.* |
HINT:
- *: It may take up to 5 or 6 minutes until the values are displayed.
- When no "ID Tire Inflation Pressure" has changed, rotate the tire 90 to 270°. Then recheck it.
