This unit describes the performance outcomes required to diagnose complex faults in engine management systems and determine the repair action necessary to restore system performance. It involves confirming the existence of a fault, choosing the diagnostic procedure and tools, applying the diagnostic procedure, reporting conclusions and making repair recommendations. Complex faults are outside the normal scope of a technician s diagnosis and repair work. They include intermittent faults, multi-system faults, faults introduced as a result of system repairs, and indirect faults caused by the influence of external systems, requiring the application of complex diagnostic processes to resolve.
This assessment will be conducted in the CAC classroom or simulated workplace environment in the main campus building at 8-10 Cross Street, Footscray West VIC 3012 or actual designated workplace. Assessment is to occur:
Your Assessor will use the assessment criteria in this document and will provide feedback / comment. Your Trainer / Assessor will inform you of the due date for this assessment task.Your Assessor will grade as either S – Satisfactory or NS – Not Satisfactory for the assessment. In all cases your Assessor will provide you with feedback.
Two different vehicles or machinery with disc and drum braking systems requiring servicing Tools, equipment and materials appropriate for inspecting and servicing braking systems Re-assessment Students who are unsuccessful at achieving competency at the first attempt will be offered coaching,information and additional time (other needs if required) before a second and possibly a third attempt is made.If the student is not able to satisfactorily complete the assessment after the third attempt the student will be deemed Not Competent and resulted as such.
Where a student wishes to appeal an assessment decision they are required to notify their assessor in the first instance. Where appropriate the assessor may decide to re-assess the student to ensure a fair and equitable decision is gained. The assessor shall complete a written report regarding the re-assessment outlining the reasons why assessment was or was not granted. Refer to important that assessors do not teach at the assessment but allow students to competence for themselves.Feedback is to be given at the completion of the assessment using the feedback to student. If a student does not meet a standard, the assessor is to sit down with them and assist them in their understanding. Should you disagree with the assessment outcome, you can appeal the decision as stated in the Student Handbook.
Your student record must indicate that you have all required skills and knowledge in completing the task. For each assessment, the assessor is to act as a supervisor and not interfere with the assessment. In the event that the assessment activities will impact on your safety or that of others, the assessment must be stopped immediately.
Attaching documents Attached documents are accepted but must be labelled with the following information:
Unit Name and Title, Students name, Student ID, Date of Submission, Student signature.
Assessment is mapped to the unit and must be completed by the end of each unit. This is a summative assessment, which requires each student to have adequate practice prior to undertaking this assessment The assessment consists of two tasks Assessment
For answers to written questions, reports and projects, you must:
• Print clearly in black or blue pen or type it as a word document
• Answer each of the key points and /or follow instructions
• Assessments written in pencil or are illegible will not be accepted.
Ask your assessor if you do not understand any part of the assessment. Whist your assessor cannot tell you the answer, he/she may be able to re-word a question or instruction to assist in a better understanding for you.Assessment Task 1: This is a questions and answers assessment over time. The assessor must provide students with sufficient information to complete this assessment over the duration of the full day training session. At the beginning of each review session the students would be given time to familiarise with the questions. Students would be given extra time at the end of the day to complete this assessment or to clarify facts with the Trainer/Assessor.
Assessment Task 2: For this observation, students are required to diagnose complex faults in engine management systems in three
(3) different vehicles that you have been given to by your Trainer/Assessor. Students are to collect information from appropriate workshop manuals (hardcopy or online) of the vehicle allocated by the assessor and also practically demonstrate the task given below. Student would be allocated with 60 minutes for each system type and this assessment can be conducted over the weeks as per the direction of the Trainer. Necessary feedback would be provided by the trainer at the end of each the demonstration. The assessor must follow the session plan aligning on which day to conduct the practical observation.
Making Rules Your assessor will assess the evidence submitted for the following elements, performance criteria,performance evidence and knowledge evidence to confirm that the student evidence submitted demonstrates validity, sufficiency, authenticity and confirms current skills and knowledge relevant to the unit of competency.
Your assessor will be looking for the following in this assessment task: -
Identify and confirm the work requirement
Prepare to perform diagnosis
Apply diagnostic procedures
Complete work processes
work health and safety (WHS) and occupational health and safety (OHS) requirements relating to diagnosing complex faults in engine management systems, including procedures for:
o working with high pressure petrol fuel systems
o working on vehicle high voltage ignition systems
o identifying hazards and controlling risks associated with wearing jewellery while working around high current wiring systems
Types of complex faults relating to engine management systems, including:
o intermittent
o multi-system
o introduced as a result of system repair
o indirect, caused by the influence of external systems
o injectors
o air flow meters
o temperature sensors
o pressure sensors
o throttle position sensors
Testing procedures for engine management systems, including procedures for:
o dynamic and static testing of vehicle or machinery
o component failure analysis
types, functions, operation and limitations of diagnostic testing equipment required to diagnose complex faults in engine management systems, including:
o scan tools
o oscilloscopes
procedures for accessing and interpreting scan tool system data, including:
o diagnostic trouble codes (DTCs), including:
conditions that set the DTCs
conditions for running DTCs
o live data
o freeze frame data
o waveforms
Methods and processes for documenting and reporting diagnostic findings and recommendations Competency Decision Student must satisfactorily complete each assessment tasks to be Competent (C) in the unit. Student with unsatisfactory completion of any of the assignment tasks will be deemed Not Yet Competent.
