Title
TIRE PRESSURE WARNING VALVE/ SENSOR ACTIVATION & INITIALIZATION

Component
GENERAL INFORMATION

Models
'09 Camry

INTRODUCTION:

The 2009 model year Camry 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.

During Pre-Delivery Service [PDS], the tire pressure warning valves/sensors must be activated for Japan-built vehicles by following the activation procedure in this TSB. NAP-built vehicles do not require activation, but both Japan-built and NAP-built vehicles require the TPWS to be initialized by following the initialization procedure in this TSB.

APPLICABLE VEHICLES:
- 2009 model year Camry 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.

ACTIVATION PROCEDURE:

NOTE
ONLY perform the following activation procedure on Japan-built vehicles.

1. Connect E-TAS Techstream.







2. Turn the ignition switch to the "IG-ON" position and check that the Low Tire Pressure Warning Light comes ON after blinking for 1 minute.







3. Press or remove the valve core to reduce the tire inflation pressure rapidly by 6 psi (0.4 kgf/cm2, 40 kPa), or more, within 30 seconds.

If the tire inflation pressure is NOT reduced by 6 psi [0.4 kgf/cm2, 40 kPa], or more, within 30 seconds, the tire pressure warning valves/sensors will NOT be activated.

NOTE
This operation is required for the system to be activated and MUST be performed for each tire [ EXCEPT the compact spare tire ], one at a time.

4. Check that the Low Tire Pressure Warning Light goes OFF after all the tire pressure warning valves/sensors are activated.
5. Using TIS techstream, check for TPWS DTCs.
- If NO DTCs are stored, go to step 1 of the Initialization Procedure.
- If DTCs C2111 - C2115 are stored, repeat step 3.

INITIALIZATION PROCEDURE:







1. Turn the ignition switch to the "IG-ON" mode and connect ETAS Techstream.
2. Adjust all tires [except the compact spare tire] 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.

NAP-built:
Remove the ID number labels that are attached to each wheel and place the labels in the glove box.







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.
