OEM-Plus (Deep-Spectrum)

This tier extracts raw ECU calibration files, software version trees, and live parameter identifiers—not just DTC codes—via manufacturer-grade diagnostic platforms. Technicians capture bus traffic across CAN, LIN, and FlexRay networks during key events like cold starts or load transitions. This reveals how subsystems interact under real conditions, exposing hidden interactions that scan tools obscure.

Non-invasive structural diagnostics include ultrasonic thickness mapping of suspension mounts, infrared thermal profiling of brake systems, and acoustic emission testing for micro-fractures. These techniques detect latent degradation in electronic and composite components without disassembly. Data feeds into a digital twin of the vehicle’s current health state, useful for predictive planning.

All raw data is preserved in a tamper-evident archive, with metadata including vehicle mileage, battery voltage at capture, ambient temperature, and diagnostic tool serial number. This allows re-analysis after software updates or incident reports. The goal is not just diagnosis but preserving a verifiable record of system behavior at a point in time.
