TPM Initialization
NOTE:
Initialization is NOT required if re-inflating tires to the currently specified tire pressure.
NOTE:
- If the signals from all the wheels are received, initialization is completed. Initialization can be confirmed through the tire pressure warning light.
- Initialization is completed when the Data List "ID Tire Inflation Pressure" display shows the correct pressures.
- It may take up to a few minutes until the values are displayed. If the values are not displayed after a few minutes, perform troubleshooting according to the inspection procedure for DTCs C2121/21 to C2124/24.
- If initialization has not been completed successfully, DTC C2177/77 is stored after a vehicle speed of 8 km/h (5 mph) or more continues for 20 minutes or more.
- During test mode (sensor check mode), the system will not change to initialization mode even if the tire pressure warning reset switch is pushed.
NOTE:
Before initialization, set the air pressure of all wheels to the specified value. 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 2.9 to 4.3 psi above the specified value.
NOTE:
Tire pressure warning light will not blink until the system initialization is complete.
- Turn the power switch ON (IG).
- Press and hold the tire pressure warning reset switch for 3 seconds or more so that the tire pressure warning light blinks 3 times. See Fig 1.NOTE: On some newer models, use the steering pad switch assembly to select "TPMS" on the multi-information display and press and hold the "ENTER" switch (steering pad switch) until the tire pressure warming light blinks 3 times. See Fig 2
- Wait for a few minutes with the power switch in ON mode and turn the power switch OFF.
- Connect the Techstream to the DLC3.
- Turn the power switch ON (IG) and turn the Techstream ON.
- Enter the following menus: Chassis / Tire Pressure Monitor / Data List.
- Check that initialization has been completed.
- Confirm that the tire pressure data of all tires is displayed on the Techstream screen.
