Initializing Tire Pressure Monitor System
NOTE:
When a tire pressure sensor and/or tire pressure monitor ECU are replaced, the sensor ID must be registered to the tire pressure monitor ECU prior to system initialization. See TIRE PRESSURE SENSOR REGISTRATION .
NOTE:
Initialization is NOT required if re-inflating tires to the specified tire pressure.
NOTE:
When initializing the system, the current tire condition is stored as a standard.
CAUTION:
DO NOT push the reset switch without adjusting tire inflation pressure of all 4 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.
During initialization, the tire pressure sensor 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 4 tires have been received.
NOTE:
The initialization process is canceled if the engine switch is turned off 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 engine off is not recommended for a minimum of 20 minutes.
- Set the tire pressure of all wheels to pressure specified on the tire and loading information label.NOTE: Perform the tire pressure adjustment after the vehicle has sufficiently cooled down. If the vehicle is not sufficiently cooled down, increase the air pressure by 3-4 psi (20-30 kPa) in addition to the specified value.
- With the vehicle stopped and parking brake applied, turn the engine switch ON.
- Press and hold the tire pressure warning reset switch (satellite switch) until the tire pressure warning light blinks 3 times at one-second intervals and "PRESSURE INITIAL" is shown on the multi-information display. See Fig 1.NOTE: Initialization is usually completed in 2-3 minutes. If initialization is completed incorrectly, DTC 2177/77 is set after driving the vehicle about 20 minutes or more.NOTE: Initialization can be terminated by connecting terminals 13 (TC) and 4 (CG) of the DLC3. See Fig 2.
- Confirm that initialization is complete:
- With igniton switch OFF, connect the Techstream to the DLC3.
- Turn ignition ON. Turn Techstream ON.
- Enter the following menus: Chassis / Tire Pressure Monitor / Data List. Check the Data List for correct tire pressures.
