Toyota Venza: Transmitter ID not Registered (C2171/71)

DESCRIPTION

Each tire pressure warning valve and transmitter ID is registered to the tire pressure warning ECU.

When the ECU detects a transmitter ID code not registered in the ECU, a DTC is output.

DTC No.

DTC Detection Condition

Trouble Area

C2171/71

Transmitter ID code is not registered. (When an ID code 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 write them down before removal.
  • It is necessary to perform registration (See page ) of the transmitter IDs into the tire
    pressure warning ECU 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.

ID1 Tire Inflation Pressure

ID1 tire inflation pressure/

min.: Absolute pressure/ 0 kPa (0 kgf/cm2, 0 psi), Relative pressure/ -100 kPa (-1.0 kgf/cm2, -14 psi)

max.: Absolute pressure/ 638 kPa (6.4 kgf/cm2, 93 psi), Relative pressure/ 538 kPa (5.4 kgf/cm2, 78 psi)

Actual tire inflation pressure

If 0 kPa (0 kgf/cm2, 0 psi) is displayed for absolute pressure or -100 kPa (-1.0 kgf/cm2, -14 psi) is displayed for relative pressure, data has not been received*.

ID2 Tire Inflation Pressure

ID2 tire inflation pressure/

min.: Absolute pressure/ 0 kPa (0 kgf/cm2, 0 psi), Relative pressure/ -100 kPa (-1.0 kgf/cm2, -14 psi)

max.: Absolute pressure/ 638 kPa (6.4 kgf/cm2, 93 psi), Relative pressure/ 538 kPa (5.4 kgf/cm2, 78 psi)

Actual tire inflation pressure

If 0 kPa (0 kgf/cm2, 0 psi) is displayed for absolute pressure or -100 kPa (-1.0 kgf/cm2, -14 psi) is displayed for relative pressure, data has not been received*.

ID3 Tire Inflation Pressure

ID3 tire inflation pressure/

min.: Absolute pressure/ 0 kPa (0 kgf/cm2, 0 psi), Relative pressure/ -100 kPa (-1.0 kgf/cm2, -14 psi)

max.: Absolute pressure/ 638 kPa (6.4 kgf/cm2, 93 psi), Relative pressure/ 538 kPa (5.4 kgf/cm2, 78 psi)

Actual tire inflation pressure

If 0 kPa (0 kgf/cm2, 0 psi) is displayed for absolute pressure or -100 kPa (-1.0 kgf/cm2, -14 psi) is displayed for relative pressure, data has not been received*.

ID4 Tire Inflation Pressure

ID4 tire inflation pressure/

min.: Absolute pressure/ 0 kPa (0 kgf/cm2, 0 psi), Relative pressure/ -100 kPa (-1.0 kgf/cm2, -14 psi)

max.: Absolute pressure/ 638 kPa (6.4 kgf/cm2, 93 psi), Relative pressure/ 538 kPa (5.4 kgf/cm2, 78 psi)

Actual tire inflation pressure

If 0 kPa (0 kgf/cm2, 0 psi) is displayed for absolute pressure or -100 kPa (-1.0 kgf/cm2, -14 psi) is displayed for relative pressure, data has not been received*.

HINT:

  • *: It may take about 2 or 3 minutes until the values are displayed.
  • If no "ID Tire Inflation Pressure" data has 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 it.
