TPMS Reminder Reset - Procedure 07
NOTE:
For Sequoia, this procedure applies to vehicles from 2005 up to August 2007. For Sequoia models from September 2007, see PROCEDURE 17 .
NOTE:
Initialization is NOT required if re-inflating tires to the currently specified tire pressure.
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 monitor ECU are replaced. Set tire pressure within the specified range before initializing. If tire pressure sensor and/or tire pressure monitor ECU were replaced, ensure that tire pressure sensor IDs are registered prior to initialization. Refer to owner's manual or appropriate manufacturer service information.
CAUTION:
DO NOT push the reset switch without adjusting tire inflation pressure of all 5 tires (including the spare). 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 monitor valve sub-assembly measures the inflation pressure of the tires, and registers the signals that are transmitted into the tire pressure monitor ECU at a frequency of one per minute. The initialization process is completed when the signals from the 5 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. For this reason, once the tire pressure warning reset switch has been pressed, turning ignition switch to OFF position is not recommended for a minimum of 20 minutes.
- Set the tire pressure of all wheels (including spare tire) to pressure specified on the tire and loading information label.
- With the vehicle stopped and parking brake applied, turn the ignition switch to the ON position.
- Press and hold the tire pressure warning reset switch until the tire pressure warning light blinks 3 times at one-second intervals. See Fig 1.NOTE: Do not turn the ignition switch to OFF position during initialization (the initialization process takes about 20 minutes). Initialization will be complete if signals are received from all the wheels including the spare. Initialization will be canceled if the ignition switch is turned to OFF position during initialization.
- Confirm that initialization is complete using the intelligent tester. Check that the pressure for each tire is displayed in INIT THRESHOLD 1 to 5.
