1. Bachelor of Applied Technology
Assessment 3 Descriptor
Course: APTE 7504 Vehicle Electronic Diagnosis
Assessment name: Case Study Evaluation (in groups)
Weighting: 30% (30 Marks)
Due date: Week 15
Submission procedure: A 15 minute case study evaluation presentation is to be made by
each group with all members contributing equally.
Learning Outcomes:
This task relates to Learning Outcome 2 & 3
Purpose:
The purpose of this assessment is to evaluate a complex vehicle electronic diagnosis. The
students will judge the effectiveness of the diagnosis of a vehicle electronic system. They will
also identify the scope of the rectification process. The knowledge gained from the earlier
study on various vehicle electronic systems and the diagnostic process followed in
assessment 2 will be used in this evaluation assessment.
Instruction:
(Time for presentation – approximately 15 minutes)
Evaluate the effectiveness of fault diagnosis conducted on the vehicle electronic system in
the case study. Follow the principles of the generic six step diagnostic process and align the
symptoms to possible causes/faults based on your knowledge of the system. Also use your
knowledge to evaluate the various components which should be tested and test procedures
(data collection and analysis) which should be followed. Present your findings and evaluation
in the form of a 15 minute presentation.
You should clearly state with justification (from your evaluation) if the fault diagnosis process
was satisfactory or not. If the diagnosis was not satisfactory according to you, clearly identify
any steps or measures that could be used to improve the fault diagnosis.
In determining the rectification process you need to consider part/component replacement
and cost analysis.
You must reference all sources of information and ensure your sources are reliable.

2. Content
You must address the following:
 Follow the second generic six step process (refer to course introduction section
(week 1)) in your diagnosis. Details of the some of the steps may be similar to the
eight step diagnostic procedure (refer to course introduction section (week 1))
 Align the symptoms to possible causes/faults based on your knowledge of the
system, any available diagnostic trouble codes (DTCs) information, and scan tool
data. This will form the crucial steps (3. Evaluate and 4. Test) of the diagnostic
process. Make a fault tree analysis (FTA) diagram (also known as root cause
analysis (RCA) fishbone diagram) and/or flowchart. You will include this in your
report.
 Determine the various components and test procedures (data collection and
analysis) that you would use.
 Compare the fault diagnosis conducted in the case study with your approach
 Clearly conclude from your comparison if the fault diagnosis process in the case
study was satisfactory or not. If the diagnosis was not satisfactory according to you,
clearly identify any steps or measures that could be used to improve the fault
diagnosis.
 Determine the rectification process considering part/component replacement and
cost analysis.
Marking
You will be marked on the criteria outlined in the marking rubric and will consider how well
