Job Description
OBD Compliance Engineer - Drive System (Front Zone, Inverter, Generator & Related ECUs) Summary Owns the end‑to‑end creation, maintenance, and release of On‑Board Diagnostics (OBD) documentation for the drive system domain, including the Front Zone Controller , Inverter , Generator/Range Extender , and all related ECUs. Produces comprehensive, compliant, and audit‑ready technical descriptions , AECDs (Auxiliary Emission Control Devices) , summary tables , monitor descriptions , DTC mappings , and all related OBD deliverables. Ensures traceability from requirements and calibrations to released OBD documentation, supporting certification and regulatory submissions. Key Responsibilities 1) OBD Content Ownership & Authoring Create and maintain OBD Technical Descriptions for each applicable ECU (functional overview, diagnostic architecture, monitors, MIL logic, enable/disable conditions). Author AECD documentation for range extender/generator and any auxiliary emissions‑affecting strategies, including intent, logic, boundary conditions, and safeguards. Develop Summary Tables and cross‑references (DTC ↔ monitor ↔ enabling conditions ↔ fault thresholds ↔ freeze frame ↔ permanent DTC rules). Document DTCs (definitions, severity, detection logic, healing logic, MIL request criteria, OBD mode mapping), readiness monitors , Mode $06/monitor test results , freeze frame , and permanent DTC behavior. Capture UDS/OBD service coverage (e.g., Modes $01-$0A, UDS services, DIDs) and vehicle network details relevant to OBD. 2) Compliance, Standards, & Certification Support Align documentation to current
OBD II/UDS/WWH
‑OBD standards and regional requirements (e.g., SAE J1979/J2012, J1979
‑2, ISO 14229 UDS, ISO 27145, CARB/EPA guidance). Prepare, review, and maintain certification‑ready packages , ensuring completeness, consistency, and accuracy across all drive system ECUs. Ensure change control and traceability from requirements/calibration to final OBD documents; maintain revision history and approval records. Support regulatory and customer audits by providing clear evidence, cross‑references, and rationale for monitoring strategies and AECDs. 3) Cross‑Functional Collaboration & Inputs Work with controls, systems, calibration, diagnostics, and software teams to extract design intent, thresholds, disablements, and diagnostic behaviors. Partner with HIL/vehicle test to confirm monitor enablement, detection timing, MIL/permanent DTC behavior, and freeze frame content. Coordinate with suppliers (e.g., inverter/generator ECU vendors) for alignment on DTC definitions, UDS services, and OBD data items. 4) Data, Traceability & Quality Maintain master DTC list for drive system ECUs with consistent naming, severity, and mapping to OBD modes and service diagnostics. Keep monitor logic matrices (enable/disable, timers, counters, debouncing, environmental dependencies) and healing/confirmation logic tables updated. Implement rigorous document QA :
internal checks for completeness, consistency across ECUs, and alignment with released software/calibrations. Drive continuous improvement of templates, checklists, and document structures to streamline future releases. 5) Tools, Templates & Automation Own and evolve document templates for Technical Descriptions, AECDs, and Summary Tables to ensure uniformity across ECUs. Utilize requirements and calibration sources (e.g., Doors/Polarion/Jama, A2L/HEX, change logs) to keep OBD docs current. When applicable, generate summary tables from canonical sources (DTC databases, calibration extracts) to minimize manual errors. Qualifications 5-8+ years in OBD/diagnostics documentation , powertrain/drive systems , or emissions/diagnostics compliance roles. Strong understanding of OBD fundamentals:
DTCs, readiness monitors, Mode $06, MIL logic, freeze frame, permanent DTCs , and UDS/OBD service mappings . Familiar with EV/HEV drive systems (inverter, e‑motor, gearbox) and range extender/generator architectures; able to articulate diagnostic intent and limits. Experience with requirements management (e.g., Doors/Polarion/Jama), calibration artifacts (A2L, HEX), and network/diagnostics tools (Vector CANoe/CANape, ETAS INCA/Service tools). Excellent technical writing skills, strong attention to detail, and ability to translate control logic into clear, compliant documentation. Knowledge of regulatory guidance and certification expectations (e.g., CARB/EPA submissions for OBD/AECDs; familiarity with WWH‑OBD a plus). Work Location:
