First, take a note of the tire pressure sensor ID before replacing the spare one. Before attaching a tired pressure sensor that was taken off before, change the valve cap, nut, valve core and sensor seal and make sure the notch/flat points in the direction of the wheel during installation. Clean the area neighboring the sensor/valve hole and see that the wheel is undamaged. With pressure applied to the rear of the metal valve, push the sensor into the wheel and watch out to prevent damage as you insert the potted part first. The flat section of the seal should sit straight against the sensor's housing area. While pushing down on the sensor assembly, hand tighten the sensor nut to ensure it fits evenly with the wheel's interior design before fixing it at 6 Nm (53 in. lbs.), not making it too tight to avoid the sensor moving away from the valve stem. Before mounting the tire, line up the sensor valve stem roughly opposite to the tire changer's head or the tool you are using to prevent any harm. Put air in the tires until the pressure reaches the number recommended on the Tire Inflation Pressure Label and make sure the original type valve stem cap is in place. After installing the tires and wheels on the vehicle, lower it and if you're in a location for more than 20 minutes, drive for at least 10 minutes at more than 15 mph (24 km/h) to enable the system to learn about the new sensor ID. A new sensor ID can also be inserted into the Wireless Control Module (WCM) through the RKE-TPM Analyzer with a Scan Tool. If the sensor is not capable of being trained, then proper diagnostic information ought to be used. Any time you put in a new TPMS pressure sensor and a matching extra tire, the computer in the car needs to be programmed using a diagnostic scan tool after installation. Get the ID number from the freshly used pressure sensor and carry out the programming process called "Learn Spare Tire Sensor ID" found in Miscellaneous Functions in the WCM menu. If an electronic TPM-RKE Analyzer is used, turn the spare tire sensor to "Park"; if you do not have one, simply rotate the spare tire with a road tire so that the tire pressures are equal.
