Generic + manufacturer-specific definitions for powertrain, body, chassis, and network codes — with AI lookup across thousands of OEM sources.
Generic + manufacturer-specific definitions for every domain a vehicle's diagnostic system reports against.
Engine, transmission, fuel, ignition, emissions. Diesel, gas, EV, and hybrid systems — including OEM-extended P-codes for commercial and emerging powertrains.
HVAC, lighting, airbags, body controllers, comfort and convenience systems. Generic OBD-II body codes plus manufacturer-specific extensions.
ABS, traction control, suspension, steering, brake systems. Heavy-vehicle chassis codes from J1939 alongside light-vehicle OBD-II.
CAN bus, LIN, ECU communication faults. Lost-communication, missing-message, and bus-off events that point to wiring or controller failures.
Across thousands of OEM sources — generic OBD-II, manufacturer-specific, and J1939 SPN/FMI — resolved into one result.
Any P / B / C / U code, or a J1939 SPN / FMI pair. From a console, an API call, or a Wayne question.
The lookup spans generic OBD-II definitions and the manufacturer-specific surface for 40+ OEMs in a single pass.
Definition + domain + the most likely manufacturer interpretation, delivered in one click.
Every fault Wayne surfaces in plain English is grounded in the same 100K+ DTC reference. No hallucinated diagnoses. No best-guess interpretations.
