Applicability

Introduction

The 2009 model year Venza is equipped with a direct-type Tire Pressure Warning System (TPWS). Each tire (except the spare tire) has a tire pressure warning valve/sensor that measures tire pressure data. The data is transmitted to the Tire Pressure Warning System antenna/receiver and then to the Tire Pressure Warning System ECU.

Required Tools & Equipment

NOTE:
Additional TIS Techstream units may be ordered by calling Approved Dealer Equipment (ADE).

Verification Procedure

1. Connect TIS Techstream.





2. 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 a 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 tire pressure when the tires are cold.

3. Cycle the ignition switch to the "IG-ON" mode.

4. Check the tire pressure of all tires using TIS techstream. If the tire pressure values cannot be displayed, the system is not operating properly. Refer to the Repair Manual.

NOTE:
If the tire pressure values are not properly displayed (example: showing -14 psi, -100 kpa, etc.) the data from the transmitter has not been received.





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