How to Reset/Relearn 4Runner TPMS Light

4 Runner 2004-2007 TPMS Reset

TPMS RESET – PROCEDURE

NOTE: Initialization is NOT required if re-inflating tires to the currently specified tire pressure.

NOTE: The system will need to be initialized when tires are rotated; tires are replaced with tires of different pressures; tire pressure sensor and/or tire pressure monitor ECU are replaced. Set tire pressure within the specified range before initializing. See Initializing Tire Pressure Monitor System. When a tire pressure sensor and/or tire pressure monitor ECU are replaced, the sensor ID must be memorized by the tire pressure monitor ECU prior to system initialization. See Tire Pressure Sensor Registration.

Tire Pressure Monitor Warning Light

NOTE: The tire pressure warning light may turn on due to natural causes such as natural air leaks or tire pressure changes caused by temperature. In this case, adjusting the tire pressure will turn off the warning light.
When the tire pressure warning light does not go off, or when it comes on during driving, check tire pressure (including spare tire) and adjust as necessary. The warning light should turn off after a few minutes. If the warning light is still on even though the tire pressure is correctly adjusted, the tire could be punctured. Repair as necessary. If the warning light is still on or blinks, there is a malfunction in the TPM system. See appropriate manufacturer service information.

Under the following conditions, the system may not function properly:

  • The areas, facilities or devices that use similar radio wave frequencies are located in the vicinity of the vehicle.
  •  A radio device of similar frequency is used in or near the vehicle. l A lot of snow or ice is stuck to the vehicle, especially the wheels and around the wheel houses.
  •  The battery of the sensor has been depleted. l A tire without tire pressure monitor valve sub-assembly is used.  Tire chains are used.
  •  If any other wheels than the specified ones are used, the system may not function properly because the radio waves are differently transmitted from the tire pressure sensor.
  •  Depending on the tire type, the system may not function properly even though the specified wheels are used.

Initializing Tire Pressure Monitor System

NOTE: The system will need to be initialized when tires are rotated; tires are replaced with tires of different pressures; tire pressure sensor and/or tire pressure monitor ECU are replaced; or when a new vehicle is delivered. Set tire pressure within the specified range before initializing.

NOTE: When initializing the system, the present tire condition is stored as a standard.

During initialization, the tire pressure monitor valve sub-assembly measures the inflation pressure of the tires, and registers the signals that are transmitted into the tire pressure monitor ECU at a frequency of one per 3 minutes. The initialization process is completed when the signals from the 5 tires have been received.

1. Set the tire pressure of all wheels (including spare tire) to pressure specified on the tire and loading information label.
2. With the vehicle stopped and parking brake applied, turn the ignition switch to the ON position.
3. Press and hold the tire pressure warning reset switch until the tire pressure warning lamp blinks 3 times at one-second intervals.
4. Confirm that initialization is complete using the hand-held tester. First select “DATA LIST” on the handheld tester, then verify that the “TIREPRESS” values are displayed. It may take 5 to 6 minutes for the “TIREPRESS” values to display on the hand-held tester screen

NOTE: The initialization process takes 5 to 6 minutes to be completed. The initialization process can be terminated by connecting terminals 4 (TC) and 13 (CG) of the DLC3.

Tire Pressure Sensor Registration

NOTE: If the tire pressure sensor and/or tire pressure monitor ECU are replaced, the transmitter ID needs to be registered in the tire pressure monitor ECU prior to system initialization. To perform this procedure, the Toyota hand-held tester must be used.

Register Transmitter ID

1. Set the tire pressure of all wheels (including spare tire) to pressure specified on the tire and loading information label.
2. Connect the hand-held tester to DLC3.
3. Turn ignition switch to ON position.
4. Select the “REGIST TIRE” mode. See Fig. 14 and Fig. 20 .Registering Transmitter ID Using Intelligent Tester toyotafig20
5. Input the transmitter IDs (ID1 to ID5) using the hand-held tester and transmit it to the tire pressure monitor ECU.
6. Set the ID transmission condition to “SUCCEEDED”.

NOTE: If steps 4-6 are not completed within 5 minutes, the mode will return to the normal operation mode.

Confirmation Of Transmitter ID Registration

1. Set the tire pressure of all wheels (including spare tire) to the specified value.
2. Connect the hand-held tester to DLC3.
3. Turn ignition switch to ON position.
4. Select “DATA LIST” mode on the hand-held tester.
5. Confirm the “TIREPRESS” values are displayed on the hand-held tester screen.

4 Runner 2008-2014 TPMS Reset

TPMS RESET – PROCEDURE

NOTE: Reset is NOT required if re-inflating tires to the currently specified tire pressure.

NOTE: When a tire pressure sensor and/or tire pressure monitor ECU are replaced, the sensor ID must be memorized by the tire pressure monitor ECU. See Tire

Pressure Sensor Registration.

NOTE: If the negative battery terminal is disconnected, initialize the following system after the terminal is reconnected: Power Window Control System. Refer to owner’s manual or appropriate manufacturer service information.

Tire Pressure Monitor Warning Light

When the tire pressure warning light does not go off, or when it comes on during driving, check tire pressure and adjust as necessary. The warning light should turn off within a few minutes. If the warning light is still on even though the tire pressure is correctly adjusted, the tire could be punctured. Repair as necessary. If the warning light turns on within several hours after adjusting the tire pressure, the tire may have a slow air leak. If the warning light is still on or blinks, there is a malfunction in the TPM system. See appropriate manufacturer service information.

NOTE: The tire pressure warning light may turn on due to natural causes such as natural air leaks or tire pressure changes caused by temperature. In this case, adjusting the tire pressure will turn off the warning light. Under the following conditions, the system may not function properly:

  •  Facilities or devices that use similar radio wave frequencies are located in the vicinity of the vehicle.
  •  A radio device of similar frequency is used near the vehicle.
  •  A lot of snow or ice is stuck to the vehicle, especially around the wheels or wheel housings.
  •  Tires and wheels are installed that are not equipped with a tire pressure sensor.
  •  Snow tires or tire chains are used. l The battery of the sensor has been depleted.
  •  Wheels other than manufacturer factory wheels are used. If any other wheels than the specified ones are used, the system may not function properly because the radio waves are differently transmitted from the tire pressure sensor.
  •  Depending on the tire type, the system may not function properly even though the specified wheels are used. l Using a different type of tire in combination with genuine tires.

Tire Pressure Sensor Registration

NOTE: When a tire pressure sensor and/or tire pressure monitor ECU are replaced, the sensor ID must be memorized by the tire pressure monitor ECU. To perform this procedure, a Toyota Techstream must be used. It is not necessary to register the sensor ID(s) when only tire rotation is performed.

NOTE: Before beginning registration process on vehicles where tire pressure sensors have not been replaced, retrieve sensor transmitter ID(s) using intelligent tester or by reading the ID on the tire pressure sensor. If sensor is being replaced with a new one, make a note of the transmitter ID before installation, as it cannot be seen after sensor is installed. See Fig. 21.fig21

1. Set the tire pressure of all wheels to pressure specified on the tire and loading information label.
2. Connect the intelligent tester to DLC3. See Fig. 11.Connecting Intelligent Tester (With CAN VIM)
3. Turn the Tachstream scan tool on and the ignition switch to ON position.
4. Enter the following menus: Chassis / Tire Pressure Monitor / Utility / ID Registration.
5. Perform the procedure displayed on the scan tool.
NOTE: Tire pressure sensor IDs that were previously registered will be deleted from the memory when registration is completed.
6. Confirm the tire pressure sensor’s IDs are registered:
7. Enter the following menus: Chassis / Tire Pressure Monitor / Data List.
8. Confirm the tire pressure values are displayed for all 4 tires.

NOTE: It may take up to 2 or 3 minutes to update the tire pressure data. If tire pressure values do not display after 2 or 3 minutes, troubleshoot DTCs C2121/21 to C2124/24 (on some models, up to C2125/25).

NOTE: If the ID(s) have not been registered, DTC C2171/71 is set in the tire pressure monitor ECU after 3 minutes or more.
