Title: TIRE PRESSURE MONITORING: TIRE PRESSURE WARNING SYSTEM: C2171/71; Transmitter ID not Registered; 2016 - 2020 MY Sienna [12/2015 - ] |
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
) after registration (See page
) of the transmitter IDs into the tire pressure warning ECU after the ECU has been replaced.

|
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)

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.
