Editorial Policy

The publisher is STEP Diagnostics. Articles do not carry a personal author byline. The absence of a byline does not mean that a guide has been independently reviewed by an engineer, a vehicle manufacturer, or a certified technician.

Public diagnostic content should:

• identify the DTC, vehicle, and configuration as precisely as the available record supports;
• distinguish vehicle-specific material from general background;
• keep observations, confirmed test results, possible fault areas, and diagnostic conclusions separate;
• describe a checkable path without presenting an unconfirmed cause as a fact;
• avoid expanding a procedure to model years, engines, or configurations that have not been supported;
• use clear language without adding filler for search engines; and
• remind the reader to follow applicable safety procedures and current service information.

A DTC can appear on many vehicles while the correct diagnostic procedure can vary by model, configuration, software, and operating condition. A guide is not automatically applicable to every vehicle that stores the same code.

Each vehicle-specific guide should identify the vehicle represented by its underlying record. A year or engine range is shown only when the available information supports that range. Readers must confirm the exact vehicle and current service information before applying a test or repair procedure.

STEP treats these as different categories:

• Reported information includes the concern, symptoms, DTCs, and operating conditions supplied at the start of a case.
• Observed or confirmed facts include measurements, inspection results, and other evidence that has been recorded.
• Hypotheses are possible explanations or directions that still require testing.
• Diagnostic decisions remain the responsibility of the technician using the evidence.

Public content should not blur these categories or allow an automated system to present a hypothesis as a confirmed diagnosis.

Content may be prepared with the help of software and AI-assisted tools for organization, formatting, and consistency checks. These tools are not credited as personal authors and do not provide independent technical approval. Before publication, the content package is checked for route identity, DTC and vehicle labels, supported applicability, required sections, metadata, internal-link conflicts, and prohibited claims.

STEP does not reproduce private repair-information documents as public articles. Public guides are not a substitute for current service information, safety instructions, technical service bulletins, or manufacturer procedures applicable to the exact vehicle.

The presence of a guide on STEP Diagnostics does not mean that a vehicle manufacturer, MOTOR, ALLDATA, Mitchell 1, or another information provider has endorsed or independently reviewed that guide.

If a guide contains an incorrect DTC label, vehicle configuration, technical statement, broken link, or other material error, use the Contact page and select Product feedback.

Correction requests are evaluated against the affected article and its available context. Material corrections should update the visible content and its modification date. STEP may remove or limit a page when its applicability cannot be stated responsibly.

This policy may change as the publication process and product mature. The page will show its effective date and most recent revision date.
