Initializing Tire Pressure Monitor System
NOTE:
The system will need to be initialized when tires are rotated; tires are replaced with tires of different pressures; tire pressure sensor and/or tire pressure warning ECU are replaced. If tire pressure sensor and/or tire pressure warning ECU were replaced, ensure that tire pressure sensor IDs are registered PRIOR TO initialization. See TIRE PRESSURE SENSOR REGISTRATION .
CAUTION:
DO NOT operate the reset switch without adjusting tire inflation pressure of all tires. Otherwise, the low tire pressure warning light may not come on even if the tire pressure is low, or it may come on when the tire inflation pressure is actually normal. If you push the reset switch while the vehicle is moving, initialization is not performed.
NOTE:
When initializing the system, the present tire condition is stored as a standard.
During initialization, the tire pressure sensor measures the inflation pressure of the tires, and registers the signals that are transmitted into the tire pressure warning ECU at a frequency of one per minute. The initialization process is completed when the signals from all tires have been received.
The initialization process is canceled if the ignition switch is turned to OFF position during initialization. To initialize again, the tire pressure warning reset switch must be pressed again.
NOTE:
The initialization can be terminated by connecting terminals 13 (TC) and 4 (CG) of the DLC3. See Fig 1.
- Set the tire pressure of all wheels to pressure specified on the tire and loading information label.
- Turn the ignition switch to the ON position.
- Switch the multi-information display to the [Gear Icon] screen. See Fig 2.
- Use the Up/Down Arrow buttons, select MAINTENANCE SYSTEM, and then press ENTER (center button).
- Use the Up/Down Arrow buttons, select TPMS, and then press ENTER button.
- Press and hold ENTER button.
- When initialization completes, a message is displayed on the multiinformation display and the tire pressure warning light illuminates.
