Title
TIRE PRESSURE WARNING VALVE/ SENSOR ACTIVATION & INITIALIZATION

Component
GENERAL INFORMATION

Models
'09 Corolla

INTRODUCTION:

The 2009 model year Corolla is equipped with a direct-type Tire Pressure Warning System [TPWS]. Each wheel 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.

During Pre-Delivery Service [PDS], TPWS is require to be initialized by following the initialization procedure in this TSB.

APPLICABLE VEHICLES:
- 2009 model year Corolla vehicles.






REQUIRED SSTs:

NOTE:
- Please contact your zone Area Parts & Service Managers to order additional ETAS Techstream units.






WARRANTY INFORMATION:

REFERENCE;







- After turning the ignition to the "IG-ON" position, the Low Tire Pressure Warning Light will blink for 1 minute and then turn ON until all the tire pressure warning valves/sensors are activated.







- The Diagnostic Trouble Codes [DTCs] may be stored in the TPWS ECU until the tire pressure warning valves/sensors are activated.
- The DTCs will automatically clear when the tire pressure warning valves/sensors are activated.

INITIALIZATION PROCEDURE:







1. Turn the ignition switch to the "IG-ON" mode and connect ETAS Techstream.
2. Adjust all tires to the standard tire inflation pressure, as indicated on the Tire and Loading Information label located inside the driver's door jamb and confirm 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 to set the tire pressure initialization.
4. Turn the ignition switch to the "OFF" position and then to the "IG-ON" position.

NOTE:
It is necessary for the ignition to be in "IG-ON" mode at LEAST 5 minutes for initialization to complete correctly.

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.

6. Adjust tire inflation pressure to the specified level.

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.
