Title:
INITIALIZATION OF TIRE PRESSURE WARNING SYSTEM DURING PDS

Component
GENERAL INFORMATION

Models
'08 - '09 Sienna

INTRODUCTION:
The 2008-2009 model year Sienna is equipped with a direct-type Tire Pressure Warning System (TPWS). A Tire Pressure Warning System valve/sensor is mounted into each tire (except 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 the specification as indicated on the Vehicle Loading and Tire Information label, located inside the driver's door jam. Follow the procedure below to initialize the TPWS.

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 Sienna vehicles.

INITIALIZATION PROCEDURE:







1. Adjust all tires (except 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 switch to the "ON" position and check that 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, indicating 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 step 1.
- If the tire pressure is correct, initialization is complete.
- If the tire pressure is incorrect, check the tire pressure gauge and repeat steps 1 - 6.
