How to Initialize the Toyota Tundra Tire Pressure System
The 5 simple and easy steps on how to initialize the tire pressure sensor on a Toyota Tundra. Please follow the simple instructions below.
The tire pressure warning system must be initialized in the following circumstances:
● When rotating the tires.
● When the tire inflation pressure is changed such as when changing tire size. (When there are multiple specified pressures)
● After registering the ID codes.
When the tire pressure warning system is initialized, the current tire inflation pressure is set as the benchmark pressure.
The initialization operation
●Make sure to carry out initialization after adjusting the tire inflation pressure. Also, make sure the tires are cold before carrying out initialization or tire inflation pressure adjustment.
●If you have accidentally turned the engine switch off during initialization, it is not necessary to press the reset switch again as initialization will restart automatically when the engine switch has been turned to ON for the next time.
●If you accidentally press the reset switch when initialization is not necessary, adjust the tire inflation pressure to the specified level when the tires are cold, and conduct initialization again.
●While the position of each tire is being determined and the inflation pressures are not being displayed on the multi-information display, if the inflation pressure of a tire drops, the tire pressure warning light will come on.
The warning of the tire pressure warning system will change in accordance with the conditions under which it was initialized. For this reason, the system may give a warning even if the tire pressure does not reach a low enough level, or if the pressure is higher than the pressure that was adjusted to when the system was initialized.
5 STEPS
STEP 1
- Park the vehicle in a safe place and turn the engine switch off. Initialization cannot be performed while the vehicle is moving.
STEP 2
- Adjust the tire inflation pressure to the specified cold tire inflation pressure level. Make sure to adjust the tire pressure to the specified cold tire inflation pressure level. The tire pressure warning system will operate based on this pressure level. see detail below.
STEP 3
- Turn the engine switch to ON.
STEP 4
- Press and hold the tire pressure warning reset switch until the tire pressure warning light blinks 3 times. A message is displayed on the multi-information display. Also, “–” is displayed for inflation pressure of each tire on the multi-information display while the tire pressure warning system determines the position.
STEP 5
- Drive straight (with occasional left and right turns) at approximately 25 mph (40 km/h) or more for approximately 10 to 30 minutes.
Initialization is complete when the position of each tire is determined and the inflation pressure of each tire is displayed on the multi-information display. Initialization may take longer than approximately 30 minutes in certain situations, such as when the vehicle is stopped for a long time at traffic lights, etc.
Warning Performance Of The Tire Pressure Warning System
Initialization may take longer to complete if the vehicle is driven on an unpaved road. When performing initialization, drive on a paved road if possible. Depending on the driving environment and condition of the tires, initialization will be completed in approximately 10 to 30 minutes. If initialization is not complete after driving approximately 10 to 30 minutes, continue driving for a while. If the inflation pressure of each tire is not displayed after driving for approximately 1 hour, perform the following procedure.
●Park the vehicle in a safe place for approximately 20 minutes. Then drive straight (with occasional left and right turns) at approximately 25 mph (40 km/h) or more for approximately 10 to 30 minutes. However, in the following situations, the tire inflation pressure will not be recorded and the system will not operate properly. Perform initialization again.
●When operating the tire pressure warning reset switch, the tire pressure warning light does not blink 3 times.
●After performing initialization, the tire pressure warning light blinks for 1 minute then stays on while driving about 20 minutes. If the inflation pressure of each tire is still not displayed, have the vehicle inspected by your Toyota dealer.
Toyota Tundra Tire Pressure PSI
The following tire pressure inflation specs is applicable to the follow tire sizes.
- Tire size P255/70R18 112T
- Tire size P275/65R18 114T
- Tire size P275/65R18 114T, P255/70R18 112T (spare tire)
- Tire size P275/55R20 111H, P255/70R18 112T (spare tire)
Tire Inflation Pressure (Recommended Cold Tire Inflation Pressure)
Front tires: 30 psi (210 kPa, 2.1 kgf/cm2 or bar)
Rear tires: 33 psi (230 kPa, 2.3 kgf/cm2 or bar)
Spare tire: 33 psi (230 kPa, 2.3 kgf/cm2 or bar)
That’s all the information you need to know on how to reset the TPMS or how to initialize the tire pressure sensor system of a Toyota Tundra. Thank you very much. Erwin C. Salarda
