Initializing Tire Pressure Monitor System
NOTE:
Perform initialization AFTER transmitter ID registration is completed (if registration is required).
NOTE:
Perform initialization in the following cases:
- After tire pressures are adjusted.
- After replacement of the tire pressure warning ECU.
- After replacement of a tire pressure sensor.
- Specified tire pressure changes depending on the size or type of tire.
- Changing the standard tire inflation pressure value due to trailer towing.
NOTE:
If initialization is performed, the existing tire positions will be cleared, but will be automatically identified when the vehicle is driven at 40 km/h (25 mph) or more for 10 minutes or more.
- Set the tire pressure of all wheels (including spare tire) 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.NOTE: In winter, as the tire pressure may decrease depending on the ambient temperature, increase the air pressure by 3-4 psi (20-30 kPa) above the specified value 20 minutes after the initialization with the ignition switch in ON position.
- With the vehicle stopped and parking brake applied, turn the ignition switch ON.
- 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 (on newer models, the switch is located further down than shown in illustration).
- Turn the ignition switch OFF.
- Connect the Techstream to the DLC3. Turn the ignition switch ON, then turn the Techstream ON.
- Enter the following menus: Chassis / Tire Pressure Monitor / Data List.
- Confirm that the expected tire pressure data of all tires is displayed on the Techstream Data List screen.NOTE: If equipped, initialization can be confirmed on the Multi-information display. It may take about 2 to 3 minutes until the values are displayed. The values are displayed randomly. See Fig 2.
NOTE:
If the initialization has not been completed successfully, DTC C2177/77 is set after a vehicle speed of more than 8 km/h (5 mph) continues for 20 minutes or more.
NOTE:
Initialization can be terminated by connecting terminals 13 (TC) and 4 (CG) of the DLC3. See Fig 3.
