Initialization (From 12/2010): Initialization

WARNING: This page is about a different car, the 2011 Toyota Avalon. However, it is still accessible from the selected car via links, so may be relevant.

DESCRIPTION OF INITIALIZATION
1. Perform initialization in the following cases:
  - Before delivery of a new vehicle.
  - After replacement of the tire pressure warning ECU*.
  - After replacement of the tire pressure warning valve and transmitter*.
  - Specified tire pressure changes depending on the size or type of the tire.
  HINT:
  
  *: Perform initialization after the transmitter ID registration is completed. Refer to REGISTRATION .
2. Before initialization
  1. Set the air pressure of all wheels to the specified value. Refer to PRECAUTION .
    NOTE:
    Make sure the tires are cooled down.
INITIALIZATION PROCEDURE
1. Turn the ignition switch on (IG).

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 (1 second on, 1 second off).
  HINT:
  
  Initialization will be completed if signals are received from all the wheels (including the spare tire).
3. Turn the ignition switch off.
4. Wait for 2 or 3 minutes with the ignition switch on (IG).

  NOTE:
  - The initialization is normally completed within 2 to 3 minutes.
  - If the initialization has not been completed successfully, DTC C2177/77 is set after approximately 20 minutes.
  - The initialization can be terminated by making a short circuit between terminals TC and CG of the DLC3 connector.

CHECK THAT INITIALIZATION HAS BEEN COMPLETED

Confirm that the data of the tire pressure of all wheels are displayed on the Techstream display to confirm that the initialization has been completed.

Turn the ignition switch off.
Connect the Techstream to the DLC3.
Turn the ignition switch on (IG).
Turn the Techstream on.

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

HINT:

The initialization is completed when the Data List "ID Tire Inflation Pressure" display shows the correct pressures.
*1: 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 C2125/25. Refer to DTC C2121/21: No Signal from Transmitter ID1; DTC C2122/22: No Signal from Transmitter ID2; DTC C2123/23: No Signal from Transmitter ID3; DTC C2124/24: No Signal from Transmitter ID4; DTC C2125/25: No Signal from Transmitter ID5; DTC C2181/81: Transmitter ID1 not Received (Test Mode DTC); DTC C2182/82: Transmitter ID2 not Received (Test Mode DTC); DTC C2183/83: Transmitter ID3 not Received (Test Mode DTC); DTC C2184/84: Transmitter ID4 not Received (Test Mode DTC); DTC C2185/85: Transmitter ID5 not Received (Test Mode DTC) .
