When pre-assembling complete wheels for trucks and buses, you face a choice: OE (Original Equipment) sensors or universal sensors. The decision depends heavily on whether you know exactly which vehicle the wheels are intended for. Here's a direct comparison for pre-assembly:

1. OE sensors

These sensors are pre-configured at the factory to a specific vehicle protocol (e.g., MAN, Mercedes-Benz, Scania).

• Advantage of pre-assembly: They don't need to be programmed. Simply install, mount the tyres, and you're done. There's no risk of programming errors.
• Disadvantage: They are inflexible. If you pre-assemble wheels for a Mercedes, they cannot be quickly fitted to a DAF – the truck will not recognize the sensors.

2. Universal sensors

These sensors are "empty" when delivered and are programmed for the specific vehicle.

• Advantage of pre-assembly: Maximum flexibility. You can keep a stock of fully assembled wheels in your warehouse. You only program the sensor for the desired vehicle shortly before mounting them on the truck.
• Special feature (cloning): Universal sensors allow you to create a 1:1 clone of the installed sensor. The truck won't even notice that a new wheel has been fitted, and relearning the sensor on the vehicle is completely unnecessary.
• Disadvantage: None

In summary: For tyre dealers who serve many different customers, as well as for fleet operators with a mixed fleet, the universal sensor is the best choice due to its storage requirements.

If your commercial vehicle is equipped with original equipment (OE) sensors – that is, the sensors installed at the factory – the system is perfectly matched to the vehicle. Nevertheless, there are important points to consider during maintenance and replacement:

1. Exchange only for the exact same model

Original sensors are typically single-protocol sensors. This means they are permanently programmed to the radio protocol of your truck manufacturer (e.g., MAN, Mercedes-Benz, Scania).

• Advantage: You do not need to configure or program the sensor before installation.
• Note: You must pay attention to the part number when purchasing. An original sensor for an Actros will generally not fit a Scania, even if it looks identical.

2. The learning process (relearn)

Even if the sensor already has the correct protocol, the truck's control unit does not automatically know that a new sensor has been installed after a replacement.

• Automatic learning: Many modern trucks (e.g. Mercedes Actros) automatically recognize new sensors after a certain driving time (approx. 15–20 minutes at 20 km/h).
• Manual learning: For some models, the sensor IDs must be entered manually via a workshop diagnostic tool or the on-board menu.
• OBD: Some vehicles can only be programmed via OBD (usually only with devices from the respective manufacturers). This service usually incurs additional costs and time.

3. Battery life

The batteries in original sensors are permanently sealed and cannot be replaced.

• In trucks, these batteries last approximately 3-5 years (depending on mileage and transmission frequency).
• If a sensor fails due to a dead battery, it is often advisable to replace all sensors on one axis, as the other batteries will usually also run out of power soon.

A practical tip: Use universal sensors like the Bartec RSHD-1 or RSHD-2 instead of OEM sensors. This will save you a lot of time and effort. Universal sensors also offer maximum flexibility. Our expert will be happy to explain the specific advantages to you.

Yes, universal sensors like the RSHD-1 and RSHD-2 are suitable for trucks, buses and trailers.

A modern TPMS service tool for commercial vehicles is far more than just a "programmer." It's the central diagnostic tool that allows you to manage the entyre lifecycle of a tyre and its sensor. Here are the four main areas of application in detail:

1. Diagnosis and troubleshooting (check-in)

Before you even remove a tyre, you can use the device to take stock of its condition:

• Check sensor status: Is the sensor still transmitting? The device receives the radio signal through the tyre.
• Battery status: You can see how much power the integrated battery in the sensor has left (e.g., "OK" or "Low"). This prevents you from mounting a tyre whose sensor will be dead in three months.
• Read data: You receive precise real-time data on pressure and temperature .

2. Programming and Configuration

• Universal sensors are described as follows: You select the make, model, and year of manufacture of the truck from the menu. The device then transmits the appropriate protocol wirelessly to a universal sensor.
• ID cloning: The device reads the ID of a defective sensor and transfers exactly the same ID to a new universal sensor.
• The advantage: The truck doesn't even "notice" the swap. No programming or relearning of the vehicle is necessary, as the ID for the control unit remains the same.

3. Relearn via OBD on the vehicle

If you rotate wheels or use new IDs, the vehicle needs to learn them:

• OBD learning: The device is connected to the truck's OBD interface via cable or Bluetooth. It writes the new sensor IDs directly to the fault memory or the TPMS control unit.
• Step-by-step instructions: Devices such as the TECH350HD and TECH600HD show you exactly what to do on the display (e.g., "turn on the ignition", "take a test drive", or "press the confirmation button on the steering wheel").

4. Documentation and logging

• Service reports: Devices can generate a log documenting that all sensors were active and the pressure was correctly set at the time of vehicle handover.
• Condition reports: They can show the driver or customer in black and white when a sensor battery is almost empty or a sensor reports an unusually high temperature (indicating a grinding bearing or brake).

A typical workflow in practice:

1. Arrival: Quick scan of all wheels with the device
2. Service: Perform tyre change or rotation.
3. Programming: If necessary, adjust the new sensor to the vehicle protocol.
4. Check: Check if everything is OK

Important: Without such a device, you often cannot clear the error message on the truck's display after replacing a sensor, even if the tyre pressure is correct. Since July 2024, this could cause the vehicle to fail its mandatory vehicle inspection (MOT/TÜV).

A TPMS device with a commercial vehicle cover and a 24V adapter is required. We recommend the BARTEC TECH350HD or TECH600HD

Whether you need your own TPMS tool (service tool) depends heavily on how you manage your fleet and which sensors you use. Here's a decision-making aid based on your profile:

1. When you ABSOLUTELY need a device

• Using universal sensors: If you use universal sensors for pre-assembly or as replacements, they are usually "empty" upon delivery. Without a programming device, you cannot upload the vehicle-specific protocol.
• Own workshop: If you perform tyre changes, repairs or tyre rotation yourself, a device is essential to activate sensors, read IDs or check the battery status.
• Mixed fleet: For vehicles of different brands (e.g. Mercedes, MAN and Scania), the device helps to make cross-brand diagnoses without having to use the manufacturer's own diagnostic system (OBD) for each truck.

2. When you DON'T need a device

• Pure service provided by a service provider: If your tyres are only ever changed at a tyre specialist retailer anyway, they have the necessary equipment on site.
• Leasing fleet: When maintenance and TPMS service are fully included in the full-service leasing.

What can a TPMS device actually do?

A modern tool (e.g. Bartec Tech600HD ) offers three essential functions for the truck sector:

1. Diagnosis: You can check from the outside (through the tyre): Is the sensor still active? How is the battery doing? What is the exact temperature?
2. Programming: Transferring the correct radio protocol to a universal sensor.
3. Relearn: Transmission of the new sensor IDs to the truck's control unit via OBD interface (if OBD coverage is present).

Bartec offers a dedicated product line specifically for commercial vehicles (trucks, buses, and trailers). Since standard passenger car sensors cannot withstand the high pressures (up to 14 bar) and specialized radio protocols of commercial vehicles, you will need to use the HD (Heavy Duty) series. The most suitable Bartec sensors for your needs are:

Bartec RiteSensor RSHD series (universal sensor)

This is Bartec's universal sensor for the commercial vehicle market. It was developed to replace almost all original equipment (OE) sensors.

• RiteSensor HD (valve-based): This sensor is mounted directly on the valve.
• RiteSensor HD (Band Sensor): This sensor is mounted directly to the rim using a universal band (fits 17.5-22.5 inch rims).

Advantages of the RiteSensor HD:

• Coverage: It covers tractors, trailers and buses of almost all common brands (Mercedes, MAN, Scania, Volvo, DAF, Iveco etc.).
• Flexibility: The sensor is "empty" and is only programmed with the appropriate protocol for the respective vehicle shortly before installation.
• Durability: It is designed for the extreme loads and high pressure ranges in heavy freight transport.

The appropriate device for it

To program these sensors, you absolutely need a Bartec device with HD software .

• Bartec TECH600HD: The professional device for the commercial vehicle sector. It supports the programming of the RiteSensor HD series, handles all axle configurations (including dual tyres) and can communicate directly with the truck via a 24V OBD adapter.
• Bartec TECH350HD: The more compact entry-level solution for the workshop, which also enables the programming and reading of the HD sensors.

Summary: What you should buy

If you want to prepare wheels for different truck brands, the RiteSensor HD (uni) in combination with the TECH600HD is the safest choice. This ensures you are perfectly equipped for the new TPMS requirement according to UN ECE R141.

External sensors are mounted visibly on the outside of the rim. A connector between the valve and the external sensor enables the sensor to measure the pressure. Internal sensors are located inside the tyre and are either mounted on the inside of the valve or secured with a strap around the rim. Only internal sensors can measure temperature in addition to pressure, which is part of the EC141 standard.

With the universally applicable, brand-independent TPMS service tool TECH600HD, workshop professionals can directly read and save the stored manufacturer information, such as sensor ID or communication protocol, provided the installed sensor is undamaged. This data can then be transferred to the universal sensor RSHD-1 or RSHD-2. This creates a functionally identical clone of the original, which is immediately recognized by the TPMS control unit as a known sensor. Relearning, OBD access, or a special learning procedure is unnecessary.

Since such universal sensors can be programmed wirelessly, complete wheelsets can be prepared in advance (pre-assembly). This significantly simplifies their use on different tractors or trailers – a particularly practical advantage during seasonal changeovers.

OEM (Original Equipment Manufacturer) sensors come directly from the vehicle or system manufacturer and precisely match the factory specifications. Universal sensors are high-quality alternatives that are freely programmable and flexibly applicable. Premium universal sensors from Bartec also achieve OEM quality, offer excellent value for money, and are ideal for mixed commercial vehicle fleets. Universal sensors reduce inventory and speed up service.
