Frequently asked questions
Answers about inquiries and availability.
We discuss observation categories and document fields by phone or email. Technical diagnosis requires hands-on inspection at a licensed facility. Describe symptoms in the contact form for more focused reference guidance.
Include vehicle make, model, model year, trip type, and the module or term you are studying. OBD codes from a scan tool are helpful context but do not replace shop inspection.
Initial reference questions through the contact form are handled without charge. If an inquiry requires extended custom documentation, we explain scope before any optional paid editorial work.
Data is used only to respond to your inquiry. See our Privacy Policy for full details.
