Leading Global OEM accelerates wiring schematic automation and diagnostic efficiency with ETAS ActiveSchematics

A leading global manufacturer of agricultural and construction equipment wanted to modernize how wiring schematics were created and used within its India operations. As vehicle systems became more complex, the company’s manual processes for schematic generation and maintenance were no longer sustainable. To address this, the manufacturer partnered with ETAS to implement ActiveSchematics, enabling automated rendering of vehicle-specific wiring diagrams, improving information quality, reducing manual effort, and supporting faster, more efficient diagnostics.

Successful transition to a fully automated, data-driven workflow, boosting equipment uptime significantly.

By automating technical documentation with ETAS ActiveSchematics, the manufacturer successfully transitioned from a slow, manual schematic design process to a fully automated, data-driven workflow. This shift drastically reduced manual engineering effort and eliminated drafting errors across their Indian operations. Ultimately, the integration empowered service technicians with clear, precise, and vehicle-specific schematics, allowing them to isolate electrical faults much faster, shorten repair cycles, and significantly boost equipment uptime.

At a glance

Challenge

The customer relied on a manual, resource-intensive wiring schematic creation process that was highly prone to errors, lacked visual clarity for service technicians, and caused major diagnostic delays and project rework.

Solution

ETAS deployed ActiveSchematics, a flexible platform seamlessly integrated into the diagnostics environment that automatically renders raw engineering and harness data into precise, vehicle-specific visual diagrams within seconds.

Customer achievement

Eliminated manual drafting errors, significantly reduced team workload, and empowered technicians with intuitive, pin-specific schematic views to drastically accelerate troubleshooting times and improve overall vehicle uptime.

The challenge

Before the project began, the manufacturer relied on a fully manual and resource-intensive process for creating wiring schematics. This approach not only consumed significant engineering effort, but also increased the probability of manual errors that affected quality and consistency. The biggest issue emerged in diagnostics: incorrect or unclear wiring diagrams slowed fault isolation and extended troubleshooting times. Although accurate harness data existed, engineering schematics often lacked the clarity needed for practical service use. In addition, change management and continuous updates were complex, time-consuming, and a major source of project delays and rework.

ETAS addressed these challenges by deploying ActiveSchematics, tailored to the customer’s specific requirements and seamlessly integrated into the diagnostics platform. The solution automatically renders non-graphical wiring data into precise, vehicle-specific visual diagrams within seconds, eliminating the need for manual drafting. Because ActiveSchematics can be integrated into engineering, service documentation, and diagnostics environments, it provided the manufacturer a flexible platform for multiple use cases. ETAS also enabled intuitive, pin-specific schematic views and improved access to the latest engineering content, making complex electrical information easier to navigate, maintain, and apply in real diagnostic scenarios.

The collaboration

A key success factor was the close and highly collaborative partnership between the OEM and ETAS. From the outset, both teams worked in tight alignment to define requirements, validate concepts, and move quickly from initial discussions to a successful proof of concept. This efficient and structured approach enabled a smooth integration into existing workflows and systems while minimizing complexity throughout the implementation. Continuous exchange, iterative refinement, and hands-on collaboration ensured rapid progress and laid the foundation for a robust, scalable solution with long-term value.

Customer achievements

With ActiveSchematics, the manufacturer significantly reduced the effort and team capacity required for wiring schematic creation. Automation removed manual drafting work and eliminated manual errors, resulting in consistently high-quality schematics with improved accuracy and completeness. The solution also made it easier to connect and use the latest engineering data, while flexible output generation supported multiple use cases across the organization. For technicians, intuitive navigation and pin-specific views improved diagnostic precision and reduced the time needed to identify faults, contributing to faster service processes and improved uptime.
