Title:
TIRE PRESSURE WARNING SYSTEM INITIALIZATION

Component
GENERAL INFORMATION

Models
'08-'09 Avalon

INTRODUCTION:
The 2008-2009 model year Avalon is equipped with a direct type Tire Pressure Warning System (TPWS). A Tire Pressure Warning System valve/sensor is mounted into each tire (including the spare tire), and the measured tire pressure data is transmitted through a Tire Pressure Warning System antenna/receiver to the TPWS ECU.

During Pre-Delivery Service (PDS), the tire pressure must be set to specification as indicated on the Tire and Loading Information label, located inside the driver's door jam.

Initialize the TPWS by pressing the Tire Pressure Warning System "SET" switch.

NOTE:
The Tire Pressure Warning System valves/sensors are activated at the manufacturing plant. Only the initialization process is required during PDS.

APPLICABLE VEHICLES:
- 2008-2009 model year Avalon vehicles.







REQUIRED SSTs:

NOTE:
- Please contact your zone Area Parts & Service Managers to order additional Techstream units.
- The Toyota Diagnostic Tester (TDT) and CAN Interface Module may also be used to perform the service procedures listed in this bulletin.

INITIALIZATION PROCEDURE:







1. Adjust all tires (including the spare tire) to the standard tire inflation pressure, as indicated on the Tire and Loading Information Label on the vehicle.

NOTE:
- If there is great difference between the current temperature of the tire and wheel (for example: shop temperature) and expected temperature (for example: outdoor temperature), this needs to be considered when adjusting the tire pressure.
- Adjust the tire pressure when the tires are cold.







2. Turn the ignition to the "ON" position and check that the the Low Tire Pressure Warning Light is OFF.







3. Push and hold the Tire Pressure Warning "SET" Switch for 3 seconds until the Low Tire Pressure Warning Light blinks 3 times and then turns OFF, meaning the system is now initialized.


4. Connect the Diagnostic Tester to DLC3.
5. Select the Tire Pressure Warning System Data List.
6. Confirm that each tire pressure on the Diagnostic Tester Data List shows the set value from step1.
- If the tire pressure is correct, initialization is complete. Go to step 7.
- If the tire pressure is incorrect, check the tire pressure gauge and repeat steps 1 -- 6.

7. Remove the ID number labels that are attached to each wheel and place the labels in the glove box.
