The information you have given me about the "course" is very limited. I would need to know more to determine if it includes vehicle maintenance.
In general, courses in automotive technology, diesel technology, or transportation maintenance will include some level of vehicle maintenance instruction. This could range from basic preventative maintenance such as oil changes and tire rotations to more complex tasks such as engine repair and transmission overhauls.
However, courses in computer science, engineering, or business are unlikely to have substantial components of vehicle maintenance.
To know if a course teaches about vehicle maintenance, I suggest that you:
Read the course syllabus: The syllabus outlines the topics to be covered.
Contact the instructor of the course: They would be the best source of information about the content of the course.
Read the course description: The description is a brief overview of the course objectives.
