How to Reset / Relearn TPMS Light on TOYOTA Avalon

Toyota Avalon TPMS Reset/Relearn

 

Avalon 2007 TPMS Reset

TPMS RESET – PROCEDURE 13

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 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. 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.

Initializing Tire Pressure Monitor System

CAUTION: Set tire pressure within the specified range before initializing. DO NOT push the reset switch without adjusting tire inflation pressure of all 4 tires. Otherwise, the low tire pressure warning light may not come on even if the tire pressure is low, or it may come on when the tire inflation pressure is actually normal. If you push the reset switch while the vehicle is moving, initialization is not performed.

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

NOTE: Perform the tire pressure adjustment after the vehicle has sufficiently cooled down. If it hasn’t sufficiently cooled, increase the air pressure in the tires approximately 3-4psi (20-30kPa)

NOTE: The initialization mode can be terminated by making a short circuit between terminals No. 4 and 13 of the DLC3 connector (located under left side of instrument panel).

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 minute. The initialization process is completed when the signals from the 4 tires have been received.
The initialization process is canceled if the ignition switch is turned to OFF position prior to the completion of initialization. To restart initialization, the tire pressure warning reset switch must be pressed again.

1. Set the tire pressure of all wheels to pressure specified on the tire and loading information label.
2. With the vehicle parked in a safe place, connect the intelligent tester to the DLC3 and turn POWER switch to the ON position.
3. Turn the intelligent tester ON and navigate to the “TIREPRESS” option using the on-screen prompts.
4. Within 30 seconds of turning the ignition ON, press and hold the tire pressure warning reset switch (located to the left of the steering wheel) until the tire pressure warning light blinks 3 times at one-second intervals.
5. Wait 5 – 6 minutes, with the ignition ON, for the initialization process to complete. If the initialization has not been completed successfully, Diagnostic Trouble Code (DTC) C2177/77 is set in the tire pressure monitor ECU about 20 minutes after driving starts.
6. Confirm that initialization is complete by verifying that the correct tire pressure values are displayed on the intelligent tester.

NOTE: In winter, tire pressure may decrease due to low ambient temperatures
(about 1.45 psi (10 kPa) for every 18°F (10°C) drop in ambient
temperature). Therefore, the tire pressure warning is more likely to operate if the tire pressures are not adjusted appropriately. If the daily temperature variation is large, pressurize the tires so that they are in the specified range under cold conditions. With this adjustment, unnecessary warnings are less likely.

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 prior to system initialization. To perform this procedure, a Toyota intelligent tester (with CAN VIM) 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 8-digit number (transmitter ID) before installation, as it cannot be seen after sensor is installed.

1. Set the tire pressure of all wheels to pressure specified on the tire and loading information label.
2. Connect the intelligent tester (with CAN VIM) to DLC3. See Fig. 11.Connecting Intelligent Tester (With CAN VIM)
3. Turn the ignition switch to ON position.
4. Select the “REGIST TIRE” mode (UTILITY – REGIST TIRE).
5. Input the transmitter ID(s) (ID1 to ID4), using the intelligent tester, and transmit them to the tire pressure warning ECU. See Fig. 17 and Fig. 18 .fig17fig18
6. Set the ID transmission condition to “ID REGISTRATION COMPLETE”.

NOTE: Any previously registered ID(s) will be deleted from the memory when the registration is completed.

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

7. Turn ignition switch to OFF position.
8. Turn ignition switch to ON position. Select the “TIRE PRESS” mode on the intelligent tester.
9. Confirm that the tire pressure data is displayed for all 4 tires on the intelligent tester. This will confirm that the registration has been completed successfully.

NOTE: It may take 5 – 6 minutes to update the tire pressure data.

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


Avalon 2008-14 TPMS Reset

TPMS RESET – PROCEDURE 17

NOTE: For Sequoia, this procedure applies to vehicles from September 2007 and later. For Sequoia models from 2005 up to August 2007, see TPMS RESET PROCEDURE 7.

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

The system will need to be initialized when tires are rotated; tires are inflated to a specification different from currently logged pressures; tire pressure sensor and/or tire pressure monitor ECU are replaced. See Initialization. When a tire pressure sensor and/or tire pressure monitor ECU are replaced, the sensor IDs must be memorized by the tire pressure monitor ECU prior to system initialization. See Registration. Registration

NOTE: The transmitter ID is written on the tire pressure warning valve and transmitter. It will be unable to be read after installing the tire pressure warning valve and transmitter on the tire and wheel. Therefore, take a note of the transmitter ID before installing the tire pressure warning valve and transmitter.

1. Set the air pressure of all wheels to the specified value
2. Turn the ignition switch off.
3. Connect Techstream to the DLC3.
4. Turn the ignition switch on (IG) and the Techstream on.
5. Enter the menu items in this order: Chassis / Tire Pressure Monitor / Utility / ID Registration
6. Perform the transmitter ID registration.
7. Input the transmitter IDs (ID1 to ID5) using the Techstream and transmit them to the tire pressure warning ECU.
8. The “ID Registration is complete” is displayed on the Techstream display.
9. Confirm transmitter ID registration.
a. Enter the menu items in this order: Chassis / Tire Pressure Monitor / Data List
b. Read the “ID Tire Inflation Pressure” values.
c. Confirm that the data of tire pressure of all tires are displayed on the screen.

NOTE: l It may take up to about 2 or 3 minutes to update the tire pressure data. If the values are not displayed after a few minutes, perform troubleshooting according to the inspection procedure for DTCs C2121/21 to C2124/24 (on models with full-sized spare, up to C2125/25).

  •   If the IDs have not been registered, DTC C2171/71 is set in the tire pressure warning ECU after 3 minutes or more.
  •  If normal pressure values are displayed, the IDs have been registered correctly.
  •  If the tire pressure values are not displayed after a few minutes, the IDs may be incorrect or the system may have a malfunction.
  •  After all IDs are registered, DTC C2126/26 (Transmitter ID not Received in Main Mode) is set in the tire pressure warning ECU and the tire pressure warning light blinks for 1 minute and then comes on. When the tire pressure warning ECU successfully receives radio waves from all the transmitters whose IDs are stored in the ECU, DTC C2126/26 is deleted and the tire pressure warning light goes off.

Initialization

NOTE: Initialization is NOT required if re-inflating tires to the currently specified tire pressure. The purpose of Initialization is to tell the TPMS ECU what the inflation pressures should be for the current set of tires. Perform Initialization if the specification changes.

Also perform initialization in the following cases:

  •  After replacement of the tire pressure warning ECU. Perform initialization after the transmitter ID registration is completed.
  •  After replacement of the tire pressure warning valve and transmitter. Perform initialization after the transmitter ID registration is completed.
  •  After rotating the tires on vehicles whose front and rear tire inflation pressure standard values are different.

1. Turn the ignition switch to ON.
2. Press and hold the tire pressure warning reset switch for 3 seconds or more so that the tire pressure warning light blinks 3 times.
3. Turn the ignition switch to OFF.
4. Connect Techstream to the DLC3.
5. Turn the ignition switch to ON and turn the tester on.
6. Enter the following menus: Chassis / Tire Pressure Monitor / Data List.
7. Check that the initialization has been completed.
8. Confirm that the tire pressure data of all tires are displayed on the tester screen.

NOTE: l The initialization is normally completed within 2 to 3 minutes.

  • If the initialization has not been completed successfully, DTC C2177/77 is set after a vehicle speed of 8 km/h (5 mph) or more continues for 20 minutes or more.
  •  The initialization can be terminated by connecting terminals 13 (TC) and 4 (CG) of the DLC3 connector.
