CHAPTER 5: CONCLUSIONS AND RECOMMENDATIONS
5.1. Conclusions:
After a period of working on the graduation project, the group completed the topic
Restoration and research of Toyota Hiace 2KD-FTV engine teaching model. During the
process of researching and implementing the project, the group absorbed a large amount
of in-depth knowledge about the Diesel engine. From there, it helps members better
understand the engine electrical systems of actual vehicles.
The following are some of the groups accomplishments:
• Build a theoretical basis for restoration and research the Toyota Hiace 2KD-FTV engine
teaching model
• Renovate the functional parts of the model to operate properly, for the purpose of
teaching.
• Use AUTEL diagnostic tool to detect error codes and read live data.
• Set up pans to help students practice errors on the system. Thereby, teachers can use the
model to teach, helping students in later grades get closer to the Toyota engine system.
5.2. Recommendations:
Even though the model has been finalized, there are still imperfections. Hopefully,
the model will be improved and developed in the future to enable it to be as near to reality
as possible while still serving learners well.
