2. Safety Information and Warnings

WARNING: Read all instructions and warnings, and review all illustrations before installing. Professional Installation Only.

• These TPMS sensor assemblies are replacement or maintenance parts for motor vehicles that have a factory-installed Tire Pressure Monitor System (TPMS) only.
• Failure to follow installation instructions may result in the failure of the motor vehicle Tire Pressure Monitor System (TPMS) sensor to operate properly.
• Each TPMS sensor is designed and manufactured to operate in specific motor vehicle makes, models, and years using the proper frequencies. Only install TPMS sensors designated for your specific vehicle.
• Improper TPMS installation or the use of unauthorized TPMS sensors will cause the motor vehicle TPM System to fail to operate properly.
• Do not install TPMS sensors in damaged wheels.
• Upon completion of installation, test the motor vehicle TPM System using procedures described in the original manufacturer's service guide to confirm proper installation.
• These TPMS sensor assemblies are designed and manufactured to operate in Original Equipment wheels and tires only. If non-Original Equipment wheels and/or tires are used, the TPM system may not function correctly.
• The vehicle owner expressly assumes sole and complete responsibility for TPMS and vehicle function if Original Equipment wheels and tires are not used. Failure to ensure that the TPMS is working correctly can result in severe injury or death.
• FAILURE TO FOLLOW INSTALLATION INSTRUCTIONS OR THE USE OF IMPROPER TPMS SENSORS MAY RESULT IN THE MOTOR VEHICLE TPM SYSTEM FAILURE CAUSING PROPERTY DAMAGE, PERSONAL INJURY OR DEATH.

4. Setup and Installation

Installation of TPMS sensors should only be performed by trained professionals. Incorrect installation can lead to system malfunction and safety hazards.

General Installation Process:

1. Loosen the tire: Remove the valve cap and core, then deflate the tire.
2. Dismount the tire: Clamp the tire onto the tire changer. Adjust the valve at 1 o'clock relative to the tire separation head. Insert the tire tool and lift the tire bead onto the mounting head to dismount the head.
3. Dismount the sensor: With a screwdriver, remove the fastening screw and sensor from the valve stem. Then, loosen the nut and remove the old valve.
4. Mount sensor and valve: Slide the new valve stem through the valve hole of the rim. Tighten the screw-nut with 4.0 Nm using a positioning pin. Assemble the sensor body against the rim and tighten the screw.
5. Mount the tire: Place the tire on the rim, ensuring the valve faces the separation head at an angle of 180 degrees. Mount the tire over the rim.

Figure 2: Tire and Sensor Mounting/Dismounting Steps

Detailed Clamp-in Sensor Removal & Installation:

1. Remove Valve Core: Remove the valve core to allow all air to escape. Discard the old valve core.
2. Removing Sensor (before dismount): Remove the mounting nut from the stem and allow the sensor to fall into the wheel/tire assembly. Discard old nut.
3. With Sensor Removed: Bounce the wheel/tire to ensure the sensor has fallen free. Break the bead free from the rim on the shallow side first, then from the deep side.
4. Break Bead: Break bead at 6 o'clock and 12 o'clock positions at all times.
5. Sensor Inspection: Remove sensor and inspect for damage or tire sealants. Replace sensor if necessary. If re-installing, clean thoroughly.
6. Installing Clamp-in Sensor: Use a new grommet, mounting nut, special nickel-plated valve core, and sealing cap. Insert sensor through rim hole with flat side facing wheel. Tighten mounting nut to specified torque (refer to Schrader TPMS Application Guide).
7. Clamp-in Assembly: Ensure proper assembly of the sensor components.
8. Clamp-in Installation/Torquing: Securely install and torque the sensor.
9. Tire Installation: Position the rim so the sensor is 90° or ¼ turn to the right of the mount/demount head. Liberally lubricate tire beads. While machine rotates, maintain pressure on tire between sensor starting point and mount/demount head to keep bead in drop center of wheel. This allows tire installation without sensor damage.

CAUTION: DO NOT re-use the removed valve core. Always replace with a new electroless nickel-plated valve core (aluminum stem). Use of non-electroless nickel-plated cores with aluminum valve stems can result in galvanic corrosion and loss of tire pressure. Tighten core with an approved valve core tool to 0.23Nm - 0.56Nm (2 in-lbs. - 5 in-lbs.) - Do Not Over tighten!

5. Operating Instructions (Vehicle Relearn)

After replacing sensors, a suitably formatted scan tool is required to learn new sensor IDs. Before beginning installation and vehicle relearn, verify application fitment.

Relearn Instructions:

1. Activate parking brake. Adjust tires to vehicle placard pressure.
2. Follow TPMS scan tool prompts for vehicle application. Trigger the left-front TPMS sensor at the valve stem using the TPMS scan tool trigger. Repeat for remaining sensors in the following order: right-front, right-rear, left-rear.
3. Turn ignition to ON (engine off). Connect the OBDII cable to the vehicle's OBDII port and the TPMS scan tool.
4. When the OBDII connection is made, the scan tool will display that sensor IDs are uploading (or similar). This process may take up to 1 minute.

Under normal driving conditions, the system will automatically relearn after a tire rotation or tire replacement (if no sensor replacement occurs).

6. Maintenance

Regular maintenance of your TPMS can help ensure its longevity and accurate operation.

Best Practices for TPMS Maintenance:

• Inspect Valve Caps: A missing or improper valve cap can lead to corrosion, limiting the serviceability of a TPMS sensor. Ensure a sealing valve cap is always installed.
• Check TPMS Sensors: Periodically use a TPMS scan tool to test each installed sensor. This confirms sensor functionality and battery status.
• Replace Serviceable Parts: Compression forces, high temperatures, and corrosion can damage TPMS components. Serviceable parts (like grommets, nuts, valve cores) should be replaced anytime a tire is removed from the wheel to prevent slow tire leaks.

7. Troubleshooting

If your TPMS indicator light illuminates, follow these steps to diagnose the issue:

TPMS Light Indicators:

• Solid Light: If the TPMS light comes on and stays solid, it indicates that one or more tires have low air pressure (20% below recommended placard pressure).
  Solution: Add air to meet placard recommendation.
• Flashing Light: If the TPMS light comes on and flashes for 60-90 seconds before staying solid, it indicates a system malfunction, such as a dead sensor battery, missing sensor, broken sensor, or an incorrect sensor for the vehicle type.
  Solution: Replace sensor, relearn sensor.

Further Diagnostics:

• Access Vehicle's Computer: Use a TPMS scan tool to check for any Diagnostic Trouble Codes (DTCs) related to the vehicle's TPMS system. This can help identify system faults.
• Review Audit Report: After service, a detailed audit report from a TPMS tool can provide status, inspection notes, and service recommendations.

8. User Tips

• Always confirm the OE number (part number) before purchasing to ensure compatibility with your vehicle. If unsure, provide your VIN code to the seller for confirmation.
• While the sensors come pre-programmed for your vehicle, they require activation by a scan tool or a
