DESCRIPTION

The tire pressure warning valves and transmitters that are installed in the tire and wheel assemblies measure the air pressure of the tires. The measured values are transmitted to the tire pressure warning antenna and receiver on the body as radio waves and then sent to the tire pressure warning ECU. The ECU compares the measured air pressure values with the air pressure threshold. When the measured air pressure value is less than this threshold, the warning light in the combination meter turns on. The tire pressure warning ECU stores a DTC when the tire pressure warning valve and transmitter stops transmitting signals. At this time, forcibly transmit the signals by releasing the tire pressure rapidly. The stored DTC is cleared when the signal transmission is resumed.

Tire pressure warning valves and transmitters stop transmitting signals
  1. Tire pressure warning valve and transmitter
  2. 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.

INSPECTION PROCEDURE

1.PERFORM FORCED TRANSMISSION OF TRANSMITTER ID OF ALL WHEELS

  1. Set the tire pressure to the specified value (YARIS_NCP93 RM000000XMK06XX.html).

  1. Connect a Techstream to the DLC3.

  1. Turn the ignition switch to ON and turn the Techstream on.

  1. Enter the following menus: Chassis / Tire Pressure Monitor / Data List /

  1. Check the values by referring to the table below.

    Tire Pressure Monitor
    Tester Display
    		Measurement Item/Range
    		Normal Condition
    		Diagnostic Note
    ID1 Tire Inflation Pressure
    		ID1 tire inflation pressure /
    min.: Absolute pressure / 0 kPa (0 kgf/cm2, 0 psi), Relative pressure / -100 kPa (-1 kgf/cm2, -14 psi)
    max.: Absolute pressure / 637.5 kPa (6.5 kgf/cm2, 92 psi), Relative pressure / 537.5 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 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 kgf/cm2, -14 psi)
    max.: Absolute pressure / 637.5 kPa (6.5 kgf/cm2, 92 psi), Relative pressure / 537.5 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 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 kgf/cm2, -14 psi)
    max.: Absolute pressure / 637.5 kPa (6.5 kgf/cm2, 92 psi), Relative pressure / 537.5 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 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 kgf/cm2, -14 psi)
    max.: Absolute pressure / 637.5 kPa (6.5 kgf/cm2, 92 psi), Relative pressure / 537.5 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 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 the values are not displayed after a few minutes, perform troubleshooting according to the inspection procedure for DTCs C2121/21 to C2124/24 (YARIS_NCP93 RM000000ZUQ07CX.html).

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

  1. Check that each tire pressure data displayed on the Techstream screen has changed.

    OK:
    Each tire pressure data displayed on the Techstream screen will change to the value of the tire pressure.
    NOTICE:
    1. It takes about 2 or 3 minutes to display the updated tire pressure data.
    2. When the "ID Tire Inflation Pressure" data has not changed, reset the tire pressure to the appropriate specified value and rotate the tire 90 to 270°. Then rapidly release the tire pressure and recheck it.

  1. After confirming that all of the tire pressure data displayed on the Techstream screen has changed, set the tire pressure to the appropriate specified values.

    HINT:
    If the tire pressure data displayed on the Techstream screen has not changed after rechecking, inspect for another problem (malfunction in transmission or reception function) (YARIS_NCP93 RM000000ZUQ07CX.html).
