DESCRIPTION

Each tire pressure warning valve and transmitter measures the internal temperature of its tire as well as the tire pressure, and transmits the information to the tire pressure warning ECU along with the transmitter ID. If the measured temperature is out of the specified range, the tire pressure warning ECU recognizes it as a malfunction, outputs DTCs, and the tire pressure warning light blinks for 1 minute and then remains on.

DTC No.

Temperature inside the tire exceeds 119°C (246.2°F) more than a specified number of times.
  • Tires
  • Tire pressure warning valve and transmitter
  • Tire pressure warning ECU

HINT:

It is necessary to perform the procedure to identify the tire pressure warning valve and transmitter that is malfunctioning because it cannot be identified by the output DTC.

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 ) after registration (See page 2016 - 2020 MY Sienna [12/2015 -        ]; TIRE PRESSURE MONITORING: TIRE PRESSURE WARNING SYSTEM: REGISTRATION ) of the transmitter IDs into the tire pressure warning ECU after the ECU and/or valve and transmitter has been replaced.

PROCEDURE

1.

CHECK TIRES

(a) Check that the tires are not flat, and have no indication of air pressure drop.

OK:

Tires are normal.

HINT:

If a tire is damaged, the tire pressure warning valve and transmitter may also have been damaged at the same time.

NG

REPLACE TIRE AND TIRE PRESSURE WARNING VALVE AND TRANSMITTER
OK

2.

IDENTIFY TRANSMITTER CORRESPONDING TO DTC

(a) Set the tire pressure to the specified value (See page 2016 MY Sienna [12/2015 - 08/2016]; TIRE / WHEEL: TIRE AND WHEEL SYSTEM: INSPECTION 2017 - 2020 MY Sienna [08/2016 -        ]; TIRE / WHEEL: TIRE AND WHEEL SYSTEM: INSPECTION ).

(b) Turn the ignition switch off.

(c) Connect the Techstream to the DLC3.

(d) Turn the ignition switch to ON.

(e) Turn the Techstream on.

(f) Enter the following menus: Chassis / Tire Pressure Monitor / Data List.

(g) Display the "ID Tire Inflation Pressure" data for each wheel using the tester.

(h) Rapidly reduce the tire pressure for each wheel at least 40 kPa (0.4 kgf/cm2, 5.8 psi) within 30 seconds.

(i) Check the Data List.

HINT:

*: It may take up to 5 or 6 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 (See page 2016 - 2020 MY Sienna [12/2015 -        ]; TIRE PRESSURE MONITORING: TIRE PRESSURE WARNING SYSTEM: C2121/21-C2124/24,C2181/81-C2184/84; No Signal from Transmitter ID1 ).

Result

Condition

Detection Condition

One of "ID Tire Inflation Pressure" data (ID1 to ID4) changed.

Normal

No "ID Tire Inflation Pressure" data changed.

Transmitter corresponding to DTC

NOTICE:

  • It takes up to 5 or 6 minutes to display the updated tire pressure data.
  • When no "ID Tire Inflation Pressure" data has changed, reset the tire pressure to the appropriate specified value and rotate the tire 90 to 270°. Then forcibly transmit the transmitter ID and recheck it.
  • Record the transmitter ID and position of transmitters that are normal.

(j) When the "ID Tire Inflation Pressure" data (ID1 to ID4) has changed, repeat this procedure to identify the tire pressure warning valve and transmitter that corresponds to the DTC.

(k) When all of the "ID Tire Inflation Pressure" data (ID1 to ID4) has changed, identify the malfunctioning tire pressure warning valve and transmitter based on the recorded transmitter IDs and output DTC.

3.

REPLACE TIRE PRESSURE WARNING VALVE AND TRANSMITTER

(a) Replace the identified tire pressure warning valve and transmitter with a new one (See page 2016 - 2020 MY Sienna [12/2015 -        ]; TIRE PRESSURE MONITORING: TIRE PRESSURE WARNING VALVE: REMOVAL ).

HINT:

  • Before installing a new tire pressure warning valve and transmitter, read and write down its transmitter ID.
  • The transmitter IDs for the tire pressure warning valve and transmitters that are not replaced should be checked using the tester and recorded.

4.

REGISTRATION OF TRANSMITTER ID

(a) Register the transmitter ID for all 4 tires (See page 2016 - 2020 MY Sienna [12/2015 -        ]; TIRE PRESSURE MONITORING: TIRE PRESSURE WARNING SYSTEM: REGISTRATION ).
