ACKNOWLEDGMENTS
After more than three months of researching and implementing the project titled
“Automotive Electrical System Toyota Innova 2017,” our team has successfully
completed the graduation project on schedule. This achievement is the result of not only
our dedicated efforts, serious study, and hard work but also the invaluable support and
assistance from our teachers, the university, friends, and family. We would like to
express our sincere and profound gratitude to all.
First, we wish to convey our pride and deep appreciation to the faculty, staff, and
Board of Directors of Ho Chi Minh City University of Technology and Education,
particularly the Faculty of Automotive Engineering. At this institution, we have been
provided with access to modern specialized knowledge and a professional learning
environment, while also being equipped with essential skills for our future careers. The
experiences at this university have significantly contributed to building a valuable
foundation, enabling us to confidently step into the professional world.
We extend our special thanks to Mr. Vu Dinh Huan, our lecturer, who has
wholeheartedly guided, accompanied, and supported our team throughout the project.
Despite numerous challenges related to knowledge, resources, and time, he remained
patient, rigorous, and responsible in every working session. He not only imparted
knowledge but also inspired us with passion, a spirit of continuous learning, and
meticulousness in research. It is thanks to his invaluable guidance and support that our
team successfully completed the project “Automotive Electrical System Toyota Innova
2017” on time.
We also sincerely thank our seniors and fellow students who shared their experiences,
reso

7. Conclusion
To conclude, the voltage is not provided to the Left Mirror Motor (0V at all modes),
which is different from the normally operating voltage. Meaning that, the wire connects
the pin from the Mirror Switch (5) to the Left Mirror Motor (8) is intermittent.

CONCLUSION AND RECOMMENDATIONS
1. Conclusion
Throughout the process of researching and completing this graduation project, under
the dedicated guidance of M.S. Vu Dinh Huan, our group successfully designed and built
a model of the body electrical system of the 2017 Toyota Innova. This project not only
helped us consolidate our specialized knowledge - particularly regarding automotive
body electrical systems - but also improved our teamwork, technical thinking, discussion,
and critical thinking skills.
The main outcomes of the project include:
- Designing and simulating the body electrical system model.
- Constructing a physical model of the actual system.
- Developing practical exercises and fault simulations to support teaching and training.
- Utilizing a diagnostic tool to read, analyze, and repair system errors.
- Compiling a written report covering the theoretical background and the
implementation process.
However, the model still has some limitations, such as focusing only on basic body
electrical systems, and some components lacking aesthetic quality in their design.
2. Recommendations
To further improve and enhance the application value of the model, we propose the
following future development directions:
- Redesign the model for better aesthetics and structural durability.
- Expand the range of fault simulations to diversify training scenarios.
- Equip immobilizer on our project, rear door lock and power window.
We are aware that, due to our limited knowledge and experience, there are still
shortcomings in our work. We sincerely welcome feedback from instructors and fellow
students to help us improve both the model and our understanding of the subject matter.
