How to conduct a thorough trailer inspection

Keeping trailers on the road and operational relies on regular and effective maintenance. Here Dr Air Brake’s John Grindey looks at what you can deploy to give trailers that thorough inspection.


Modern HGV trailers are complex, integrating advanced braking systems, electronics, and safety features. As these systems become more sophisticated, the need for precise and comprehensive diagnostic tools becomes ever more critical. At Dr Air Brake we’ve been developing state-of-the-art diagnostic equipment designed to meet the rigorous demands of contemporary trailer servicing.

Remote control

Their diagnostic range provide technicians with detailed insights into the condition of a trailer’s braking system and other critical components. By accurately diagnosing issues, this equipment helps prevent potential failures that could lead to costly breakdowns or accidents. This proactive approach not only improves safety but also reduces downtime, allowing trailers to return to service more quickly.

One popular product is the Van Trailer Check (VTC), a versatile tool designed to test lighting, EBS/ABS CAN circuits, and air braking systems in trailers. The VTC is powered by a 24v system, which can be supplied either from a technician’s mobile support van or through a workshop power source, utilising a transformer from 240v/110v to 24v.

To enhance operational flexibility, the VTC is equipped with a wireless remote control. This feature allows technicians to walk around the trailer or work from a pit, operating both the air brakes and lights as a single operator. This setup eliminates the need for a tractor unit to be hitched to the trailer, streamlining the inspection process and saving valuable time and resources.

They say time is money in the logistics industry. The ability to perform quick yet thorough inspections can significantly enhance operational efficiency. That’s why we design our diagnostic equipment with user-friendly interfaces and advanced capabilities, enabling technicians to conduct comprehensive diagnostics swiftly. This streamlines the inspection process, allowing for rapid identification of issues and minimising the time trailers spend in maintenance bays.

Second generation tool

To work in conjunction with the VTC, we have upgraded the Code Talk diagnostic reader. This second-generation product is a state-of-the-art trailer diagnostics tool designed to streamline diagnostic processes and optimise efficiency. The latest generation of Code Talk II features upgraded software, doing away with various dongles. The connection is now effortlessly established by using the provided breakout lead. Code Talk II stands as a globally recognised handheld fault code reader, catering to the diverse range of trailer manufacturers’ ECU systems, including industry leaders such as WABCO, HALDEX and KNORRBREMSE, with a specialised focus on trailer ABS/EBS brake systems.

This advanced product simplifies usage by seamlessly interfacing with the trailers ECU via the EBS socket, and the breakout lead. Code Talk II reads and clears any fault codes present within the trailer, ensuring a comprehensive diagnostic analysis. Moreover, it is equipped to display realtime air pressures, wheel speeds and system voltages, offering invaluable insights for effective trailer diagnostics.

Meeting regulations

This efficiency translates directly into increased service demand capabilities. With quicker turnaround times, service providers can handle a higher volume of inspections and repairs. This is particularly crucial during peak periods when the demand for freight transport surges. By equipping service centres with these advanced diagnostic tools, they help ensure that more trailers are road-ready, meeting the industry’s high demands.

Safety is non-negotiable when it comes to HGV operations. Regulatory compliance is another critical aspect, with stringent standards governing the maintenance and safety of commercial vehicles. Our diagnostic equipment plays a vital role in ensuring that trailers meet these regulatory requirements, with tools that provide accurate readings, essential for maintaining compliance with legal and safety standards.

Furthermore, this equipment helps identify potential issues before they become serious problems. For instance, detecting wear and air leaks in braking systems or issues with electrical parts can prevent accidents and enhance the safety of both the vehicle operator and other road users. By ensuring that trailers are in top condition, they help their clients uphold the highest safety standards, protecting their reputation and reducing liability.

The logistics industry is the lifeline of our economy, ensuring the continuous flow of goods across regions. At Dr Air Brake, we take pride in supporting this vital sector by providing the tools and technology necessary for maintaining the health of HGV trailers. It’s a commitment to innovation and quality that helps develop to develop products that often exceed the expectations of customers.

As our products continue to evolve and expand, the focus remains on delivering solutions that enhance the efficiency, safety, and reliability of trailer servicing and inspections. We understand that the demands of the logistics industry are constantly changing, and we are dedicated to staying ahead of these changes, providing customers with cutting-edge technology and exceptional service.

Delivering diagnostics

In conclusion, Dr Air Brake is dedicated to improving the efficiency and safety of HGV trailer servicing and inspections. Its diagnostic equipment is designed to meet the needs of today’s complex trailer systems, providing quick and accurate diagnostics that keep trailers on the road and operating efficiently. By partnering with us , service providers can enhance their capabilities, ensuring that they can meet the high demands of the logistics industry while maintaining the highest standards of safety and compliance.
