Diagnostic Systems and ISOBUS Interoperability for Agricultural Machinery

Cojali is exhibiting its Jaltest AGV diagnostics module and Jaltest ISOBUS automation solutions to provide fault detection and digital interoperability for heavy agricultural machinery. These systems enable workshops and operators to standardize equipment maintenance and implement precision farming controls across mixed-fleet environments.

Advanced Diagnostics for Fleet Maintenance
At EIMA International 2026 (10 to 14 November in Bologna, Italy), the company will display its technologies in Hall 37, Stand C19. The Jaltest AGV diagnostic module provides technicians with direct access to electronic control units on agricultural machinery. By integrating interactive wiring diagrams, troubleshooting guides, and system-level technical data, the software allows maintenance personnel to isolate faults and reduce diagnostic times. The system architecture supports continuous database updates to accommodate new vehicle protocols, ensuring compatibility with evolving hardware variants within modern agricultural fleets.

Implement Automation and ISOBUS Integration
The company's second technological focus is the Jaltest ISOBUS range, engineered to digitize analog implements and ensure control compatibility between tractors and tools regardless of the original equipment manufacturer. This hardware framework includes the Jaltest ICM Sprayer and the Jaltest ICM Orchard Sprayer, which interface directly with spraying equipment to precisely regulate fluid application rates based on active telemetry. For physical implement guidance, the JT-AutoSteer system utilizes Real-Time Kinematic (RTK) positioning to minimize overlapping passes, maintaining tight spatial tolerances to optimize field trajectories.

Dynamic Control Systems for Material Spreading
Further extending this interoperability framework, the Jaltest ICM Spreader equips fertilizer spreaders with automated digital control loops. Recognized in the "Technical Evolution" category at the EIMA 2026 Technical Innovations Contest, this control module executes proportional ground speed adjustments, automated material weighing, and dynamic section control. By linking the physical mechanics of the spreader with standard ISOBUS terminals, the system dynamically adjusts output to maintain consistent material application rates, thereby reducing fertilizer waste during precision agricultural operations.

Additional Context
This section details technical specifications and competitive benchmarking not included in the original news release.

In the multi-brand agricultural diagnostics market, Jaltest AGV primarily competes with platforms like the TEXA NAVIGATOR TXT Multihub (using the IDC5 Agri software environment). Both diagnostic tools connect to standard diagnostic ports to read error codes across mixed fleets. While TEXA is highly benchmarked for its extensive European vehicle coverage and pass-thru capabilities, Jaltest is typically evaluated on its integrated technical repair data and guided troubleshooting pathways that link specific trouble codes directly to component schematics.

Within the ISOBUS automation sector, the Jaltest ICM modules compete with systems like Trimble’s Field-IQ and Topcon’s Apollo application controllers. Competitive benchmarks for these implement controllers focus on control loop latency, flow meter response times, and standard RTK precision, which generally targets 1 to 2 centimeters of pass-to-pass accuracy. The core technical advantage of universally applicable ISOBUS control units lies in standardizing the digital supply chain on the farm, allowing operators to route control inputs from a single in-cab display to multiple disparate implements using the ISO 11783 communication standard.
