Wheel Nut

Start by elevating the vehicle safely on a support then remove the tire/wheel assembly for tire pressure sensor (Snap In Style) replacement. Before installation use a new Schrader(R) tire pressure monitor (TPM) coupled with a new TORX screw on the tire to rim mount. Pull the tire pressure sensor off the tire pressure valve stem by removing the TORX screw, handling it with caution to protect the clear aluminum wheel coating. The next step requires pulling the tire pressure valve stem completely through the rim. Follow these installation instructions: position the valve flats to match up with the surrounding snap enclosure while respecting TPM and TORX screw limitations to single-use applications. Secure the tire pressure sensor onto the valve stem then replace it with a new TORX screw and apply 1.3 N.m of torque (11.5 lb in). Engineers must use an approved tire mounting lubricant that does not contain silicon or base compounds which corrode. Tire soap applied to the rubber valve stem allows a tire valve stem mounting tool to easily pull the stem into the valve hole along its parallel axis in the rim. The Snap Fit TPM sensors start their delivery in an OFF position yet transition automatically into an operational state once the tire reaches its inflated level so technicians can perform standard vehicle programming. The installation process concludes by attaching the tire to its rim while installing the tire/wheel assembly onto the vehicle before lowering it down and learning about the tire pressure sensors.

A suitable vehicle support enables replacing the Tire Pressure Sensor through first removing tire/wheel assemblies from the vehicle. You should position the sensor's cap and valve on a clean surface before tire dismounting but only use aluminum caps alongside nickel-plated valves to stop corrosion. To pry the tire bead away from the wheel you should direct the bead breaking fixture at a 90 angle relative to the valve stem followed by gently pushing a tire iron or pry bar counterclockwise of the sensor body to lift the tire bead past the mounting and dismounting head. The tire machine helps the operator move tire/wheel assemblies in a clockwise direction to move tire beads outside the wheel rim before taking off the tire. Users must thoroughly remove all tire sealant residue from both the wheel surface and tire before moving on to remove the sensor components. Wipe away all dirt and debris from the grommet area before directing the sensor's air passage away from the wheel when you install it through the wheel hole. When installing the sensor nut position the sensor body at a right angle to the wheel's interior surface before tightening it to 7 Nm (62 inch lbs.). When replacing the tire position your mounting/dismounting head at 180 degrees to the valve stem and set the bead transition area 45 degrees left of the valve stem. You should begin by rotating the tire/wheel combination clockwise during bead transfer to the wheel rim interior before repeating this action on the outer bead before wheel installation. Service replacement tire pressure sensors enter the market in OFF mode but require the motorized rotation of tire/wheel assemblies to at least 20 mph (32 km/h) speeds for ten seconds to set their internal roll switch to the closed position. Learning of tire pressure sensors completes the installation process after the tire/wheel assembly is fitted onto the vehicle and then the vehicle is lowered.

Start replacing the Tire Pressure Monitor (TPM) sensor by elevating the vehicle on a proper support system. Separate the tire from the wheel by first removing the tire and wheel assembly. Gently separate the TPM sensor nut and TPM sensor while keeping the components safe throughout the removal process. During sensor replacement keep the air outlet oriented towards the wheel exterior and maintain a parallel relationship between the sensor body and wheel surface while torquing the sensor nut to domestic vehicles require 4 Nm (35 inch lbs.) and export vehicles require 12 Nm (106 inch lbs.). Place the sensor into the valve stem hole while cleaning the sensor grommet sealing area afterward before threading the sensor nut. Finish the tire/wheel assembly by returning and reattaching the tire following vehicle lowering. Programming TPM sensors requires the Tire Pressure Monitor (TPM) Programming Tool (J 41760) to activate the programming mode through the Remote Control Door Lock Receiver (RCDLR). Proceed with programming the sensors following a simultaneous lock-unlock button press on the key fob to access programming mode. After programming the TPM sensors you must ensure each wheel position generates a horn chirp following the program sequence of left front, right front, right rear, and left rear. The programming mode terminates under three conditions: turning off the ignition system or completing sensor programming or remaining in this mode for more than five minutes without sensor programming.

Start by having a suitable vehicle support lift your car before you take off the tire and wheel assembly to replace the Clamp In Style Tire Pressure Sensor. Place the sensor components on a clean area before tire removal while ensuring the aluminum cap matches nickel-plated valve material to stop corrosion. Position your bead breaking fixture 90 degrees from the valve stem and insert your tire iron or pry bar slightly clockwise of the sensor body before prying the tire bead over the mounting/dismounting head. The tire machine allows you to perform clockwise rotations on the tire/wheel assembly to move tire beads outside of the wheel rim before repeating this procedure for the inner bead. Use proper cleaning solutions to eliminate all remaining tire sealant inside the tire's surface and on the wheel surface. You need to disconnect the tire pressure sensor nut followed by the sensor removal. Clean the grommet sealing surface first then position the sensor wheel hole entry with the air passage toward the wheel's outside and tighten the sensor nut to 7 N.m (62 lb in) while the sensor body remains parallel to the wheel internal surface. Position the mounting/dismounting head 180 degrees from the valve stem and align the bead transition area 45 degrees counterclockwise of the valve stem before rotating the tire/wheel assembly clockwise to transfer the tire bead inside the wheel rim followed by a similar process for the outer bead. The service replacement tire pressure sensor arrives in an OFF state requiring at least 10 seconds of 32 km/h (20 mph) tire/wheel assembly rotation to deactivate its internal roll switch before conducting remote control door lock receiver (RCDLR) memory learning. Finish the installation by mounting the tire/wheel assembly onto the vehicle then drop it to the ground before triggering the required learning sequence for tire pressure sensors.

The first step to replace the Tire Pressure Sensor involves lifting the vehicle onto a proper support while removing the tire/wheel assembly. Place the sensor's cap and valve on a clean and dry surface before tire removal from the wheel while maintaining the aluminum cap with its nickel-plated valve undisturbed by other materials. Position the bead breaking fixture at 90 degrees from the valve stem then position the mounting/dismounting head for the tire iron or pry bar entry slightly clockwise of the sensor body as you pry up the tire bead over the head. Use the tire machine to switch the tire/wheel assembly clockwise to move one tire bead toward the outer rim edge then repeat the process for the inside bead before tire dismantling is complete. The process requires complete removal of any remaining tire sealant inside the tire before extracting the sensor and its nut. To mount the sensor start by cleaning all debris from the grommet sealing area next slide the sensor into the wheel hole with air flow facing in a specific direction then tighten the sensor nut and position the sensor body at a 90 degree angle to the inside wheel surface to 7 Nm (62 inch lbs.). To install the tire correctly position the mounting/dismounting head 180 degrees from the valve stem and the bead transition area 45 degrees counterclockwise of the valve stem before using the tire machine to rotate the tire/wheel assembly clockwise when moving each tire bead inside the wheel rim. Service replacement tire pressure sensors come from the factory set to OFF mode causing their unique identification codes to remain unavailable for learning into the passenger door modules (PDMs) memory until the sensors spend ten seconds at 32 km/h (20 mph). To finish the process install the tire/wheel assembly on the vehicle then lower the vehicle before learning the tire pressure sensors.

The vehicle needs to sit on an appropriate suspension during replacement of the Tire Pressure Indicator Sensor. Separate the tire/wheel assembly from the vehicle. Position the tire valve and cap on a clean dry area during tire extraction to protect the pressure sensor. The aluminum cap serves alongside the nickel-plated valve which require no substitution by alternative materials. Keep the bead breaking fixture facing 90 degrees from the valve stem while the tire machine fixture distance should meet the defined tolerance with both the tire bead and the sensor during tire removal process. Proper wheel maintenance includes cleaning tire sealant from inside both wheel and tire surfaces following tire removal. Take out the tire pressure sensor nut followed by removing the sensor component. Position the air passage side of the sensor toward the wheel face when you insert it into the valve stem hole of the wheel. Clean the wheel's sensor grommet area from all debris before installation and tighten the sensor nut to keep the body of the sensor parallel with its inner surface at 7 Nm (62 lb in). The tire mounting process requires space between the tire machine or irons, tire beads, and sensor during tire placement back onto the wheel. Start by installing the tire onto the wheel after which follow with tire/wheel assembly placement on the vehicle then slowly lower the vehicle. Training on tire pressure sensors should complete your learning.

To finish the process install the tire/wheel assembly on the vehicle then lower the vehicle before learning the tire pressure sensors.

Starting to replace the Tire Pressure Indicator Sensor requires lifting the vehicle onto an appropriate support. Take the tire/wheel assembly from the vehicle before placing the aluminum cap and nickel-plated valve on a clean area following removal. Approach the bead breaking fixture at a 90-degree angle relative to the valve stem then insert the tire iron or pry bar just before the sensor body clock-wise to pry the tire bead onto the mounting/dismounting head. Use the tire machine to move the tire/wheel assembly by giving it a clockwise spin while you shift the bead to the wheel rim's exterior surface and then do the same sequence for the inner bead. Complete the wheel removal operation by thoroughly cleaning all inside surfaces of the wheel free from tire sealant. Start by removing two parts: the tire pressure sensor nut followed by the sensor itself. Check the grommet seating region for dirt before placing your new sensor wheel-hole with its air-port facing in the opposite direction of the wheel. All replacement parts must come with the correct part numbers and usage of specified thread locking compounds, lubricants, or sealants must be adhered to. After placing the sensor body at a right angle to the wheel's interior surface, tighten the sensor nut to 7 Nm (62 lb in). The mounting/dismounting head needs to be at 180 degrees from the valve stem with the bead transition area situated 45 degrees counterclockwise relative to the valve stem during tire installation. Proper tire/wheel assembly rotation should be clockwise to place tire beads within the wheel rim. This process should be duplicated for the external bead. The sensor arrives in OFF mode as part of a service replacement tire component but requires wheel rotation exceeding 32 km/h (20 mph) for at least 10 seconds to become active. End your procedure by mounting the tire-wheel assembly onto the vehicle as you lower it down before learning the sensors for tire pressure.

Start by elevating the vehicle on an appropriate support before you can replace the Tire Pressure Indicator Sensor. Disassemble each tire assembly from the vehicle but keep aluminum cap and nickel-plating valve components on a clean surface after removal. Substitute materials must be avoided for both aluminum cap and nickel-plating valve. To separate beads with a tire machine position the breaking fixture at a 90-degree angle from the valve stem while maintaining equal space between wheel parts at all times. Clear all remaining tire sealant from the inside walls of both the wheel and tire following tire removal. Disassembly begins with removing the tire pressure sensor nut followed by removing the tire pressure sensor. To install the sensor wash all dirt off the wheel's sensor grommet sealing area before putting the device into the valve stem hole air exhaust direction facing away from the wheel and tighten the sensor nut to 7 N.m (62 lb in) torque while adjusting the sensor body position along the wheel's interior surface. When mounting the tire back on the wheel ensure all parts including the tire machine and irons along with the tire bead and sensor maintain proper tolerance distances. To finish up the tire installation sequence first secure the tire on the wheel after that attach the wheel and tire assembly to the vehicle and lower it down before learning the tire pressure sensors.

With the vehicle lifted properly and tire/wheel assembly removed, the following steps that should be followed to replace the Tire Pressure Sensor. Before you take the tire on; lay the cap of the sensor and its valve on a clean surface while the cap should be aluminum and the valve nickel-plated so that it is not easily corroded. When detaching the tire bead from the wheel, locate the bead breaking fixture 90 degrees away from the valve stem and locate the mounting/dismounting head parallel with the tire iron or pry bar could get inserted only slightly clockwise of the sensor body. Use the tire machine applying the tire/wheel assembly clockwise in the movement and transfer the tire-bead to the exterior side of the wheel rim, reiterate for the internal beads preceded to remove the tire from the wheel. If any of the tire sealant is there, wash all residual liquid sealant from the interior of the tire and wheel surfaces, and wash out the tire pressure sensor nut, as well as the sensor itself. For installation, clean the grommet sealing area of any dirt or debris, insert the sensor into the wheel hole with the air passage to the back of the wheel, install the sensor nut while aligning the body of the sensor with the inside surface of the wheel while tightening it to 7 Nm (62 inch lbs.). Position the mounting/dismounting head 180 degrees away from the valve stem and position the bead transition area 45 degrees counterclockwise of the valve stem before replacing the tire. Roll the tire/wheel assembly in a clockwise direction to move the tire bead to the inside of the wheel rim, followed by the other bead to the exterior, before the tire installation on the wheel. Not to mention that a service replacement tire pressure sensor is shipped in OFF mode, thus prohibiting the sensor's unique identification code from being learned into the memory of the antenna module; to turn the sensor away from OFF mode, spin the tire/wheel assembly at a rate of ring over 32 km/h (20 mph) for at least 10 seconds. Finally, mount the tire/wheel assembly to the vehicle, lower the vehicle, and teach the tire pressure sensors.

The first step to replace the Tire Pressure Sensor involves lifting the vehicle onto a proper support while removing the tire/wheel assembly. Place the sensor's cap and valve on a clean and dry surface before tire removal from the wheel while maintaining the aluminum cap with its nickel-plated valve undisturbed by other materials.

To finish the process install the tire/wheel assembly on the vehicle then lower the vehicle before learning the tire pressure sensors.

Begin by elevating the vehicle using a proper support to access the tire/wheel assembly for replacement. The sensor's valve and cap must be placed on a clean surface before tire dismount while ensuring both components are aluminum and nickel plated to avoid corrosion. Start by orienting the bead breaking fixture perpendicular to the valve stem then insert the tire iron or pry bar in an area slightly behind the sensor body to pry the tire bead over the mounting/dismounting head. Rotate the tire/wheel assembly with a tire machine in a clockwise direction to move tire beads toward the wheel rim's exterior before repeating the procedure for the inner bead position. Check inside the tire alongside wheel surfaces for remaining tire sealant before starting tire replacement. The installation process starts by uninstalling the tire pressure sensor nut then removing the sensor. Prior to mounting the sensor begin by cleaning the grommet area and insert the sensor into the wheel hub with the air outlet located at the wheel's back then torques the nut to 7 N.m (62 lb in) while maintaining parallel sensor positioning relative to the wheel internal surface. To start reinstalling the tire position the mounting/dismounting head at 180 degrees of the valve stem then set the bead transition area at 45 degrees counterclockwise from the valve stem before rotating the tire/wheel assembly in a clockwise direction to move both tire beads inside the wheel rim while repeating the procedure for the outside bead. Service replacement tire pressure sensors require 32 km/h (20 mph) wheel speed maintenance for minimum 10 seconds so the internal roll switch can activate before PDMs memory learning begins. Install the tire/wheel assembly onto the vehicle before lowering it to learn the tire pressure sensors.
