Component
GENERAL INFORMATION

Models
'11 Corolla

INTRODUCTION:

The 2011 model year Corolla 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. The data is transmitted to the Tire Pressure Warning System antenna/receiver and then to the Tire Pressure Warning System ECU.

During Pre-Delivery Service (PDS), the tire pressure warning valves/sensors must be initialized according to the procedure in this TSB.

4. Cycle the ignition switch to the "OFF" position and then to the "IG-ON "position.
5. Check the tire pressure values of all the tires using ETAS Techstream.

NOTE
- It can take 2 - 3 minutes for the tire pressure values to be displayed on the ETAS Techstream Data List.
- If the tire pressure values CANNOT be displayed on the ETAS Techstream screen, the initialization is NOT completed. Repeat steps 2 - 4.
