NOTE: If this step is not completed within 300 seconds, registration mode will be canceled. 5) Perform the procedures displayed on the Techstream. NOTE: It may take up to about five to six minutes to update the tire pressure data. If the values are not displayed aer several minutes, perform troubleshooting according to the inspection procedure for DTCs C2121/21 to C2124/24. If the IDs have not been registered, DTC C2171/71 is set aer three minutes or more. 6) Confirmation of transmitter ID registration: a) Enter the Techstream menu items in this order: Chassis / Tire Pressure Monitor / Data List. b) Confirm that the expected tire pres- sures of all tires are displayed on the screen. DEMOUNTING/MOUNTING PROCEDURES CAUTION: e tire should be demounted from the wheel using the tire changer manufacturer's instructions. Use the following information to avoid damage during the demounting/mounting procedures. NOTE: The system will need to be initialized when tires are replaced with tires of different pressures and when the tire pressure sensor and/or the tire pressure monitor ECU is replaced. NOTE: When a tire pressure sensor and/ or tire pressure monitor ECU is replaced, the sensor ID must be memorized (regis- tered) by the tire pressure monitor ECU prior to system initialization. See "Reset procedures." NOTE: If the negative battery terminal is disconnected, initialize the following power systems aer the terminal is reconnected: window control system, back door system, sliding door system and the moon roof. Refer to the owner's manual or the appropriate manufacturer service information. TIRE PRESSURE SENSOR CAUTION: e use of tire sealants is strictly prohibited for vehicles equipped with the TPMS. Tire sealants can clog tire pressure sensors. CAUTION: Be sure to reinstall tire valve caps, or dirt or moisture could get into the valve core and cause air leakage. Use only the original valve cap. If any other valve cap is used, it may corrode or melt, and become extremely difficult to remove. NOTE: e average life of the grommet of the tire pressure sensor is approximately five years, at which time it must be replaced. If the valve is leaking air, but it is less than five years old and the grommets are in good condition, retighten the valve nut to 35 in.-lbs. (4 N.m). Whenever the tires must be replaced, replace the grommets for the tire pressure sensors as well. NOTE: If the tire pressure valve sub- assembly is going to be replaced, make a note of the eight-digit number (transmitter ID) before installation, as it cannot be seen aer sensor is installed (see Figure 3). Whenever a new sensor is installed, it will need to be registered in the tire pressure monitor ECU. Removal 1) When replacing a wheel or tire, the tire pressure sensors must be set up in one of the following ways: • Remove the sensor from the old wheel and install it in the new wheel. Keep the same wheel with the tire pressure sensor, and replace only the tire. • Use a new wheel and sensor (the new sensor must be registered aer installation). 2) Remove the wheel. Remove the cap and valve core, and release air from the tire (see Figure 4). NOTE: Keep the removed cap, valve core, nut and washer. 3) Aer ensuring that air is sufficiently released, remove the nut and washer that is used to hold the tire pressure sensor and drop the sensor inside the tire. NOTE: Be careful not to damage the tire pressure sensor due to interference between the sensor and tire bead. 4) Aer dropping the tire pressure sensor into the tire, disengage the bead using the shoe of the tire remover (see Figure 5). 5) Remove the bead on the upper side following the usual procedure.
