Introduction

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.

The tire pressure sensing transmitter used for the Tire Pressure Monitoring System (TPMS) on 2004 - 2006 model year 4Runner vehicles needs to be activated during Pre-Delivery Service (PDS).

Applicable Vehicles

^ 2004 - 2006 model year 4Runner 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.

Activation Procedure





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.cm, 40 kPa) or more within 30 seconds. If the tire inflation pressure is NOT reduced by 6 psi (0.4 kgf/sq.cm, 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 the spare tire) one at a time.

Check that the Low Tire Pressure Warning Light goes OFF after all the tire pressure sensing transmitters are activated.

NOTE

After all tire pressure sensing transmitters are activated, the Low Tire Pressure Warning Light will come ON whenever the tire pressure in any of the tires falls below 24 - 27 psi (1.65-1.9 kgm/sq.cm, 165 - 185 kPa).

3. Check that the sleep mode Diagnostic Trouble Codes are NOT stored in the system. If the sleep mode Diagnostic Trouble Codes are stored increase the tire inflation pressure of all 5 tires to 44 psi (3.0 kgm/sq.cm, 300 kPa) and repeat steps 1 - 3.

4. If the Low Tire Pressure Warning Light comes ON increase the tire inflation pressure to 32 psi (2.2 kgm/sq.cm, 220 kPa) and check that the warning light goes OFF.





5. Adjust the tire pressure of all tires (including spare tire).
