Summary and ConclusionsWith continual volatility in agricultural economy and smaller crop growing windows, product uptime has become crucial to manage effective and efficient agricultural practices. Repair service and diagnostics are the key to ensure product uptime. Service literatures aid the dealer technician to perform the repair activities. One such is the service/technical manual provided by manufacturers to enhance dealer technician productivity. These manuals offer concise information to identify and resolve issues in any farm equipment thereby ensuring distinctive product quality and customer experience.In the context of service manuals prerequisite for the content quality is to have the procedures tested at vehicle level or at sub-components level. This entails huge efforts in procurement, disassembly/assembly, and part replacements. The proposed solution is to utilize hardware-in-loop methodology to create a virtual sub-component model that is calibrated to test real-time scenarios. Such models enable user to induce failures and simultaneously validate the service content thereby avoiding hardware failures and replacement costs.This paper deals with such case studies of how the realms of content validation can collaborate with hardware-in-loop methodology to validate multiple sensor/actuator or system failures on a virtual component and simulate failure scenarios occurring in the field to deliver effective diagnostic content.
