Title
TIRE PRESSURE WARNING SYSTEM ACTIVATION AND INITIALIZATION

Component
GENERAL INFORMATION

Models
'11 Camry, Camry HV

INTRODUCTION:
The 2011 model year Camry; Camry HV 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:






REQUIRED SSTS:

NOTE:
Additional Techstream units may be ordered by completing the order form on ETAS and faxing it to (416) 431-8342






WARRANTY INFORMATION:

REFERENCE:







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







- The Diagnostic Trouble Codes (DTCs) listed 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.
- For NAP vehicles, proceed to the Initialization Procedure.

1. Connect E-TAS Techstream.







2. Cycle the ignition switch to the "IG-ON" position and check that the Low Tire Pressure Warning Light blinks for 1 minute and then remains illuminated.







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 ETAS 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:

NOTE:
Perform the following initialization procedure for BOTH NAP-built and Japan-built vehicles.







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.

NOTE:
To adjust tire pressure correctly when outside temperature is significantly colder or warmer than shop temperature. Follow the procedures outlined in the Tire Inflation Pressure Compensation and Adjustment service bulletin (TSB1317)

NOTE:
Adjust the tire pressure when the tires are cold

NAP-built:
Remove the ID number labels that are attached to each wheel and discard.







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.

The ignition switch MUST be left in the "IG-ON" position for AT LEAST 5 minutes for initialization to complete.

NOTE:
Initialization will NOT complete if the ignition switch is not left in the "IG-ON" position for AT LEAST 5 minutes.

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.
