Tire Monitor System - Transmitter Activation Procedure
PRE-DELIVERY SERVICEPD007-06
REVISED
January 18, 2006
Title:
TIRE PRESSURE SENSING TRANSMITTER ACTIVATION & INITIALIZATION
Models:
'07 Camry
TSB REVISION NOTICE:
^ March 29, 2006: The title has been changed. The Introduction has been updated.
^ The Activation Procedure has been split into 2 procedures: "Activation Procedure: Japan-built ONLY" and "Initialization Procedure: NAP-built & Japan-built". Previous versions of this TSB should be discarded.
Introduction
The 2007 model year Camry is equipped with a direct type Tire Pressure Warning System (TPWS). A tire pressure sensing transmitter is built into each tire valve, and the measured tire pressure data is transmitted through a Tire Pressure Warning System antenna to the tire pressure monitoring system receiver.
During Pre-Delivery Service (PDS), the tire pressure sensing transmitters must be activated for Japan-built vehicles following the activation procedure in this TSB. Both Japan-built and NAP-built vehicles require the TPWS to be initialized following the initialization procedure in this TSB.
Applicable Vehicles:
^ 2007 model year Camry vehicles.
Reference Information
NOTE:
^ After all the tire pressure sensing transmitters are activated, the flashing Low Tire Pressure Warning Light goes OFF.
^ The Diagnostic Trouble Codes (DTCs) listed below may be stored in the system until the tire pressure sensing transmitters are activated.
^ The codes will automatically clear when the tire pressure sensing transmitters are activated.

Required SSTs
Activation Procedure:
Japan-built ONLY
NOTE:
ONLY perform the following activation procedure on Japan-built vehicles.
1. Turn the ignition switch to the "ON" position and check that the Low Tire Pressure Warning Light blinks.
2. Press the valve core to reduce the tire inflation pressure rapidly by 6 psi (0.4 kgf/sq.2, 40 kpa) or more within 30 seconds. If the tire inflation pressure is NOT reduced by 6 psi (0.4 kgf/sq.2, 40 kpa) or more within 30 seconds, the tire pressure sensing transmitters will NOT be activated.
This operation is required for the system to be activated and must be performed for each tire (including full-size spare tire, except compact spare tire), one at a time.
3. Check that the Low Tire Pressure Warning Light goes OFF after all the tire pressure sensing transmitters are activated.
4. Check that the sleep mode DTCs are NOT stored in the system. If the sleep mode DTCs are stored, increase the tire inflation pressure of all 5 tires to 44 psi (3.0 kgm/sq.2, 300 kpa) and repeat steps 1 - 3.
Initialization Procedure:
NAP-built & Japan-built
NOTE:
Perform the following initialization procedure for both NAP-built and Japan-built vehicles.
1. Adjust the tire pressure to the specified level as indicated on the Tire and Loading Information label on the vehicle. Check 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.
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.
2. Push and hold the Tire Pressure Warning "SET" switch for 3 seconds until the Low Tire Pressure Warning Light blinks 3 times.
3. Ensure the Low Tire Pressure Warning Light goes OFF.
When the Low Tire Pressure Warning Light goes OFF, it is necessary to leave the ignition ON for 5 minutes to allow the TPWS ECU to initialize with the current tire pressure.
NOTE:
Do NOT turn ignition switch OFF until initialization is complete. If initialization has NOT been completed, it is NOT possible to enter the TPWS test mode.
