Position Overview

We are seeking an experienced Service Diagnostic Manager to drive end-to-end diagnostic readiness for new product-development projects and provide dedicated engineering support for active production models.

The position will lead the strategy, development, validation and deployment of Diagnostic Service Manuals, service diagnostic tools, interactive wiring diagrams and field-resolution processes. The role requires strong knowledge of vehicle or equipment diagnostics, DTC logic, UDS protocols, electrical schematics and diagnostic-tool validation.

Key Responsibilities

Diagnostic Strategy and DSM Development

• Lead Diagnostic Service Manual development for new projects, from the early architecture stage through production readiness.
• Review engineering fault-strategy sheets and conduct failure-mode and coverage-gap assessments.
• Ensure complete diagnostic coverage of component and system failures.
• Audit Diagnostic Trouble Code parameters and verify accurate SPN-FMI mapping.
• Coordinate with engineering teams to identify, track and close diagnostic gaps.
• Conduct physical fault simulations on vehicles or equipment.
• Validate whether DSM troubleshooting procedures accurately identify and resolve root causes.
• Convert diagnostic matrices into web-based or HTML SPN-FMI manuals.
• Publish and maintain diagnostic content on the designated online service portal.
• Maintain document accuracy, version control and release discipline.

Diagnostic Tool Readiness

• Define functional requirements for service diagnostic tools based on project architecture.
• Specify live parameters, configurable write parameters, control functions and advanced troubleshooting capabilities.
• Coordinate with engineering teams and software suppliers during tool development.
• Validate tool functionality against approved requirements and close identified gaps.
• Collect user feedback and recommend diagnostic-tool feature enhancements.
• Coordinate development scope, quotations, financial approvals, purchase orders and supplier deliverables.
• Validate new software builds before production or service release.
• Manage Annual Maintenance Contracts for diagnostic-tool suites.
• Administer software licences and resolve service-tool support tickets.
• Monitor vendor performance, ticket closure and software-release quality.

Interactive Service Wiring Diagrams

• Obtain engineering schematics, system circuits, component-location diagrams and 2D/3D sensor layouts.
• Coordinate with external suppliers for the development of interactive wiring diagrams.
• Validate circuit, connector, component and location accuracy.
• Release approved wiring diagrams through the online service portal.
• Maintain and update diagrams based on engineering and field changes.

Current-Product Diagnostic Support

• Act as the technical owner for diagnostic field issues affecting active production models.
• Analyse field concerns, diagnostic data and customer feedback to identify root causes.
• Coordinate with service, engineering, quality and supplier teams for issue resolution.
• Update existing DSMs, diagnostic software and service wiring diagrams based on field learnings.
• Drive continuous improvement in diagnostic accuracy, serviceability and repair turnaround time.
• Track recurring issues and recommend preventive improvements.

Required Technical Skills

• Strong understanding of UDS diagnostic protocols.
• Hands-on experience with DTC and SPN-FMI fault logic.
• Experience developing or validating Diagnostic Service Manuals.
• Knowledge of diagnostic standards, service-critical parameters and control functions.
• Ability to interpret 2D/3D electrical schematics and wiring diagrams.
• Experience with diagnostic authoring tools and service diagnostic applications.
• Experience administering diagnostic portals or equivalent web-based service platforms.
• Knowledge of fault simulation, root-cause analysis and troubleshooting.
• Experience managing diagnostic-software suppliers and technical support tickets.
• Understanding of vehicle, engine, construction-equipment or off-highway electrical and electronic systems.

Preferred Competencies

• New-product diagnostic readiness
• Field-failure resolution
• Cross-functional project management
• Software and supplier management
• Technical documentation
• Analytical and problem-solving ability
• Stakeholder communication
• Attention to detail
• Configuration and change management
