Initializing Tire Pressure Monitor System
NOTE:
Perform initialization AFTER the transmitter ID registration procedure (if registration is required).
NOTE:
Perform initialization in the following cases:
- After replacement of the tire pressure warning ECU.
- After replacement of a tire pressure sensor.
- Specified tire pressure changes.
- Changing the standard tire inflation pressure value due to trailer towing.
NOTE:
Initialization is NOT required if re-inflating tires to the specified tire pressure.
- 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.
- With the vehicle stopped and parking brake applied, turn the ignition switch to the ON (IG) 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
- Turn the ignition switch off.
- Connect the Techstream to the DLC3. Turn the ignition switch ON (IG) and turn the Techstream ON.
- Enter the following menus: Chassis / Tire Pressure Monitor / Data List.
- Confirm that the correct tire pressure data of all tires is displayed on the Techstream screen.
NOTE:
If the initialization has not been completed successfully, DTC C2177/77 is stored after a vehicle speed of 5 mph (8 km/h) or more continues for 20 minutes or more.
NOTE:
Initialization can be terminated by connecting terminals 13 (TC) and 4 (CG) of the DLC3. See Fig 2.
