Ръководствата за диагностика, започват от 1990 година и са разделени в следните раздели:
Купе и аксесоари
Шаси и задвижване
Двигатели
Дизелови двигатели
Информация / Комуникация
Контрол на климатика
В тези раздели, съдържанието е разделено по системата на автомобила и модел на автомобила. Съдържанието покрива тестовите процедури за електронно контролираните системи и техните под системи като хидравлика, пневматика и механика.
Описанието на функциите, процедурите по ремонта и тестовите процедури на прости системи са описани накратко. Ръководствата за диагностика са предназначени за използване само от авторизиран Мерцедес персонал за тестове, диагностика и сервиз на автомобилите на Мерцедес-Бенц. Всички документи са на английски език и нямаме намерение да ги превеждаме. mercedes-bulgaria.com не носи отговорност за евентуални щети причинени от неправилна процедура при провеждане на диагностика и препоръчваме такава да се извършва от специализирани сервизи.Съкращения (акроними), използвани в ръководствата за диагностика.
