For automotive professionals, the right diagnostic tools are not just accessories—they are essential investments that can significantly impact efficiency and service quality. When discussing top-tier diagnostic equipment, names like Snap-on often come to mind, sometimes associated with price tags reaching upwards of $16,000 for a single scan tool. But what justifies such a cost, and are there comparable alternatives that offer similar capabilities? Let’s delve into the world of high-end automotive diagnostics, using the VAS 6356 test instrument box as a prime example of advanced technology in this field.
The VAS 6356 test instrument box is a crucial component designed for use with diagnostic testers such as VAS 5052A, VAS 6150, VAS 6150A/B/C, and VAS 6160A. It’s engineered to handle all current testing instrument tasks required during guided fault finding, effectively mirroring and even enhancing the test instrument technology found in the VAS 5051B and its integrated instrumentation. This tool is not just about reading codes; it’s about deep, comprehensive vehicle analysis.
Design and Advanced Features of High-End Diagnostic Tools
The VAS 6356 is built with future-proof technology in mind, particularly for capturing rapid signal patterns like those found in CAN bus systems. It allows for the simultaneous operation of two rapid Digital Storage Oscilloscope (DSO) channels alongside a highly precise, high-resolution multimeter. This multimeter is capable of measuring current, voltage, resistance, continuity, and diodes, providing a broad spectrum of diagnostic capabilities in one device.
A standout feature is its 8-channel data logger, which can simultaneously display all input signals. This is invaluable for technicians needing to monitor and record complex interactions within vehicle systems over time. Furthermore, the galvanic isolation of the voltage supply, multimeter, and DSO channels enables “high” measurements across different sources without needing an earth tap. This is particularly crucial when working with modern vehicles, including hybrid drives. The system is also adaptable, prepared for modules beyond just a multimeter, such as specialized units for measuring insulator resistance, and is ready for microvolt measurements with an optional sensor head.
The high storage volume is another critical aspect, ensuring that signals both before and after a fault event are adequately recorded. This is vital for secure and targeted diagnostics, allowing technicians to thoroughly analyze the conditions leading up to and following an issue. Complex trigger links across all input channels facilitate the diagnosis of intricate processes, making it easier to pinpoint the root cause of problems in complex systems. Ease of use is also prioritized; automatic parameter settings based on sensor selection streamline operation, and a specification graph curve library enables specified/actual value comparisons, aiding in accurate assessments.

Accessories, Calibration, and Support
To further extend its capabilities, recommended accessories for the VAS 6356 include a 1800A current clamp (VAS 6356/11), a 12V connection cable (VAS 6356/16), and an equipment trolley (VAS 6556) for enhanced mobility and organization within the workshop.
Calibration is recommended initially after two years, and then annually to maintain accuracy and reliability. The tool comes with a 24-month warranty, reflecting the manufacturer’s confidence in its durability and performance. Manufactured by AVL DiTEST GmbH in Fürth, the VAS 6356 is backed by AVL’s technical support, accessible via US and Canada specific phone numbers, ensuring users have access to expert assistance when needed.
High-End Diagnostics: Investment and Alternatives
While a $16,000 scan tool like those from Snap-on represents a significant investment, tools like the VAS 6356 offer a compelling alternative, providing a similar level of advanced diagnostic capability. The cost of high-end scan tools reflects their sophisticated technology, comprehensive features, and the extensive support and updates that often accompany them. For workshops specializing in complex diagnostics, particularly those working with European brands or hybrid vehicles, the investment in advanced tools like VAS 6356 can be justified by increased efficiency, diagnostic accuracy, and the ability to tackle a wider range of vehicle issues.
Ultimately, the decision to invest in a high-end scan tool, whether it’s a Snap-on or a system like VAS 6356, depends on the specific needs and focus of your automotive service business. Tools like the VAS 6356 demonstrate that top-tier diagnostic performance is achievable, offering features and robustness comparable to more widely recognized brands in the high-end market. Exploring these options ensures that professionals can make informed decisions to equip their workshops with the best possible diagnostic solutions.
