Navigating the complexities of modern diagnostics is no easy task. Here, tool specialist Sealey explains how investment in sophisticated diagnostic equipment is essential to enable technicians to fault-find efficiently.
Vehicle diagnostics have developed over the last 30 years, with a greater requirement for different types of diagnostic equipment. The choice has grown from simple code readers to advanced systems capable of complex multi-manufacturer analysis and diagnostics.
The evolution of vehicle diagnostics advanced significantly with the introduction of the OBD-II system in the mid-1990s. This standardisation provided a more consistent and universal approach to diagnostic tools across various brands and models. As software capabilities improved, tools could perform more detailed diagnostics and monitor a wider range of vehicle systems. The focus at the time remained primarily on emissions-related diagnostics. The Sealey VS8812, an entry-level EOBD code reader, builds on these capabilities by offering comprehensive system checks beyond just emissions. EOBD code readers provide a clear starting point for diagnosing and resolving vehicle issues, enabling efficient troubleshooting and maintenance. By accurately interpreting diagnostic trouble codes, these tools ensure precise and targeted repair strategies, which helps improve overall vehicle performance and reliability.
More sophisticated tools As vehicles grew more complex, with advanced electronic systems and interconnected sensors, the demand for more sophisticated diagnostic tools became clear. This led to the development of multi-brand diagnostic software that could interface with a wide range of vehicles, offering comprehensive diagnostic capabilities beyond just the powertrain and emissions systems. These tools could identify issues across multiple systems, including the engine, transmission, ABS, and airbag systems, making them indispensable for mechanics and repair shops.
The newest generation of multimanufacturer diagnostic tablets, featuring a fast wireless multitasking Android operating system, offer extensive coverage and OElevel diagnosis. They are built for maximum convenience and efficiency, allowing independent garages to provide a complete diagnostic service for cars, SUVs and vans. Software features include: maintenance functions, technical information and data management; read/clear codes; live data (record/playback and print); actuation tests; airbag reset; battery configurations; DPF regeneration; electronic parking brake; ABS bleeding; injector programming; key programming; oil service reset; steering angle calibration; throttle reset; TPMS; diagnostic over internet protocol (DOIP); and FCA gateway by connecting to the 8+12 interface in the car.
Multimeters
In addition to advanced diagnostic tools, multimeters play a crucial role in modern vehicle diagnostics by allowing technicians to measure voltage, resistance, and current in various electrical systems. This makes it easier to pinpoint issues in components such as sensors, wiring, and actuators. Sealey offers a wide range of multimeters designed to meet the demands of today’s complex vehicles. Among these, the range TA320 multimeter stands out for its CAT III 1000V rating, aiming to ensure safety and accuracy when diagnosing a wide range of electrical faults. For even higher voltage systems, such as those found in electric and hybrid vehicles, Sealey’s PPHY CAT IV 1000V high voltage tester provides reliable testing that complies with EV and hybrid standards.
Regular diagnostic tests are crucial for maintaining a vehicle’s health, as they can identify minor issues before they develop into more significant and expensive problems. By detecting early signs of wear or malfunction, these tests allow mechanics to address the root cause of a problem quickly, ensuring the right component is fixed the first time. This accuracy is essential because misdiagnosing an issue can lead to unnecessary repairs, increased labour costs, and extended downtime for the vehicle. Effective diagnostics not only save money and time but also enhance safety and reliability, giving vehicle owners peace of mind that their cars are running smoothly and efficiently.
Sealey continues to adapt to the evolving needs of the servicing industry, providing products that enable efficient diagnosis, maintenance, and vehicle repairs. Designed for precision and ease, its servicing range provides essential tools and equipment to optimise vehicle performance, enabling timely repairs and maintenance, and minimising downtime.
