TPMS Tire Pressure Sensor Instruction Manual

1. Introduction

This manual provides essential information for the installation, operation, and maintenance of your GANGLE 433MHz Tire Pressure Monitoring System (TPMS) sensors. These sensors are designed to replace or maintain parts for motor vehicles equipped with a factory-installed TPMS. Proper installation and adherence to these instructions are crucial for the correct functioning of your vehicle's TPMS.

The TPMS continuously monitors your vehicle's tire pressure and alerts you if a tire pressure falls significantly below the recommended inflation. This system is vital for safety, fuel efficiency, and tire longevity.

2. Safety Information

WARNING:

• Read all instructions and warnings, and review all illustrations before installing.
• Professional installation is highly recommended.
• Failure to follow installation instructions or the use of improper TPMS sensors may result in the motor vehicle TPMS system failure, causing property damage, personal injury, or death.
• 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, it is the vehicle owner's responsibility to ensure the TPMS is working correctly.

CAUTION:

• Each TPMS sensor is designed for specific motor vehicle makes, models, and years. Only install sensors designated for your specific vehicle.
• Improper TPMS installation or the use of unauthorized TPMS sensors will cause the motor vehicle TPMS system to fail.
• Do not install TPMS sensors in damaged wheels.
• After installation, test the motor vehicle TPMS system using procedures described in the original manufacturer's service guide.
• DO NOT re-use removed valve cores. Always replace with a new electroless nickel-plated valve core (aluminum stem).
• Tighten valve cores with an approved tool to 0.23Nm - 0.56Nm (2-5 in-lbs). Do not overtighten.

3. Setup and Installation

This section outlines the general steps for removing and installing TPMS sensors. It is crucial to follow these steps carefully, ideally by a qualified professional.

Sensor Removal (Clamp-in Type)

1. Remove the valve core to allow all air to escape. Discard the old valve core.
2. Remove the mounting nut from the stem and allow the sensor to fall into the wheel/tire assembly. Discard the old nut.
3. Bounce the wheel/tire to ensure the sensor has fallen free.
4. Break the bead free from the rim on the shallow side first, then from the deep side.
5. If the sensor was installed, remember to locate and mark its position on the tire prior to removal. Position the Tire/Wheel Assembly so the sensor is at 6 and 12 o'clock positions when breaking the bead.
6. Liberally lubricate the bead and position the wheel assembly so the mount/demount head is slightly ahead of the sensor. The tire should dismount without coming into contact with and damaging the sensor.
7. Inspect the sensor for damage. If it is to be re-installed, clean it thoroughly.

Sensor Removal (Snap-in Type)

1. Remove the T-10 screw from the back of the sensor using a 20140 tool.
2. Use a standard TTV tool to pull the old rubber valve stem through the hole and discard.

Sensor Installation (Clamp-in Type)

1. Always use a new grommet, mounting nut, special nickel-plated valve core, and sealing cap.
2. Insert the sensor through the rim hole with the flat side of the sensor facing toward the wheel.
3. Tighten the mounting nut to the specified torque as defined in the Schrader TPMS Application Guide, using the 20142 Mounting Nut Torque Tool.

Sensor Installation (Snap-in Type)

1. Attach a TTV tool to the valve stem.
2. Insert the valve into the sensor body, aligning the flats on the brass stem to the flats on the receiving hole of the sensor body.
3. Use a valve pull tool to prevent the valve from spinning.
4. Use the T-10 tool to assemble the valve to the sensor body before inserting the assembly into the wheel rim hole.
5. To install the sensor into the wheel, use a standard TTV tool to pull the stem straight through the rim hole. A rubber mallet or similar device can be placed between the tool and rim flange to ensure the valve is pulled straight.
6. Position the rim so that the sensor is 90° or turn to the right of the mount/demount head.
7. Liberally lubricate the beads of the tire. While the machine is rotating, maintain pressure on the tire between the starting point of the sensor and the mount/demount head to keep the bead of the tire in the drop center of the wheel. This allows the tire to be installed without damage to the sensor.

4. Operating Instructions

Vehicle Relearn Procedure

After installing new TPMS sensors, the vehicle's system needs to learn the new sensor IDs. Verify application fitment before beginning.

Driving Relearn Method:

1. Activate the parking brake. Adjust tires to vehicle placard pressure.
2. Insert key, turn ignition ON (engine off), and then OFF.
3. Exit vehicle and allow to sit for 15 minutes.
4. For the system to learn new TPMS sensor IDs, the vehicle must be operated for several minutes at a speed of 15 mph (25 kph) or more.

OBDII Relearn Method (if supported by scan tool):

To avoid driving the vehicle, an OBDII relearn is possible with some OBDII TPMS scan tools.

1. Activate the 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. This process may take up to 1 minute.
5. If the OBDII procedure fails (not all TPMS scan tools are capable), the vehicle must be driven to complete the relearn process.

How Direct TPMS Works

TPMS sensors are installed in each wheel and send pressure information to a receiver located in your vehicle. When the system detects low tire pressure or a malfunction, it causes the TPMS indicator light to appear on your dashboard.

5. Maintenance

Regular maintenance of your TPMS system ensures its longevity and accurate performance.

Step-by-Step Best Practices:

1. Check for the Light: If the TPMS indicator light illuminates on the dashboard during start-up and then disappears, the system is operational.
2. Inspect Valve Caps: A missing or improper valve cap can lead to corrosion, limiting the serviceability of a TPMS sensor. Always ensure a sealing valve cap is installed.
3. Check TPMS Sensors: Use a TPMS scan tool to test each installed sensor. This confirms any alerts indicated by the TPMS light.
4. 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 and sensor history.
5. Review Audit Report: After service, a detailed "audit report" should be provided, showing the status of the TPMS system and recommended services.

Important: Compression forces, high temperatures, and corrosion can damage TPMS components. Serviceable parts (grommets, mounting nuts, valve cores, sealing caps) should be replaced anytime a tire is removed from the wheel to prevent slow tire leaks and ensure proper TPMS function.

6. Troubleshooting

Understanding TPMS indicator lights can help diagnose common issues:

TPMS Light Indicator:

• Solid Light: If your TPMS light comes on and stays solid, it indicates that one or more tires have low air pressure.
• Solution: Add air to meet the recommended placard pressure.
• Flashing Light: If your TPMS light comes on and flashes for 60-90 seconds before staying solid, it indicates a system malfunction. This could be a dead sensor battery, a missing sensor, a broken sensor, or an incorrect sensor for the vehicle type.
• Solution: Replace the faulty sensor and perform a relearn procedure.

Relearn Procedure Failure:

• If the OBDII relearn procedure fails, the vehicle must be driven at 15 mph (25 kph) or more for several minutes to complete the relearn process.

8. User Tips

• Always ensure your tires are inflated to the vehicle manufacturer's recommended pressure, typically found on a sticker inside the driver's side door jamb or in the owner's manual.
• When replacing tires, always have the TPMS sensors inspected and serviced (new grommets, nuts, and valve cores) to prevent future leaks or malfunctions.
• If you frequently switch between summer and winter tires, consider having a dedicated set of TPMS sensors for each set of wheels to simplify the seasonal changeover.
• Keep a record of your TPMS sensor IDs if possible, as this can assist technicians during relearn procedures.
