Recognition of Prior Learning (RPL)
RPL is a formal process that recognises skills developed through previous training, work or life experience,
which match a unit of competency in a training course. If you believe you already have the skills covered in this
unit of competency, discuss this with your trainer, who will provide you with instructions for applying for RPL.
National Recognition / Credit Transfer
Qualifications or statements of attainment issued by other Registered Training Organisations are recognised by
the College. Where this unit of competency is equivalent to a unit of competency previously completed with
another provider, credit transfer will be offered and the course length adjusted accordingly. It is the
responsibility of the student to provide the relevant evidence of qualifications or statements of attainment issued
by other Registered Training Organisations, which will be verified by the College prior to credit transfer being
applied.
Support Services
Your trainer/assessor is able to clarify any aspect of an assessment task prior to it being administered. This
may include clarifying: knowledge and skills covered during the training program; the meaning of written
assessment questions; performance standards for practical assessments; and marking criteria.
Once the assessment process has commenced however, the assessor is not able to provide any intervention
or guidance, unless it is to prevent an unsafe act from being performed.
Please ask for help when you need it, as your trainer/assessor may not be aware that you have not understood
aspects of the training program, or are not feeling confident enough to engage in assessment activities.
Plagiarism
Plagiarism is using the words or ideas of others and presenting them as your own. Plagiarism is a type of
intellectual theft. It can take many forms, from deliberate cheating to accidentally copying from a source without
acknowledgement. In your assessments you must come up with your own ideas, however, at times you may
need to make reference to work that has been conducted by others. Important points to be aware of:
 Know what plagiarism is – refer to http://www.plagiarism.org/ for more information
 Reference your work / acknowledge all of your sources
“All of the following are considered plagiarism:
 turning in someone else's work as your own
 copying words or ideas from someone else without giving credit
 failing to put a quotation in quotation marks
 giving incorrect information about the source of a quotation
 changing words but copying the sentence structure of a source without giving credit
 copying so many words or ideas from a source that it makes up the majority of your work, whether you
give credit or not...”
Where a student plagiarises, the student will need to resubmit their work and will be given a first and
final warning for misconduct. If a student plagiarises a second time, their CoE may be cancelled
immediately for serious misconduct.

Question 5: What is an Electronic Stability Program system (ESP)?
It is the computerizedsafely technology which is present in modernvehicles. This is designedto recoverthe stabilityof vehicle by reducinganddetectingthe
loss of direction therefore Securingthetyres fromskiddinguncontrollably (Khedkar etal., 2015). This also works like theinvisible safetynet that controls
andmonitors the driving.
Question 6: List three (3) ways the PCM reduces torque to the drive wheels when the Traction Control System (TCS)
system is in traction control mode?
Traction control is the chance which could be found on the Vehicles equipped by the anti-lock brake
system which is also known as ABS. It is the add-on feature that recovers the traction when the vehicle is
accelerating on a slick or wet surface. When traction control is required then it also applies the brakes on
the wheel of drive that is losing the traction also. Some of the ways that how the BCM reduces the torque
to drive the wheels-
By growing the exhaust gas recirculation flow.
By decreasing or cutting of the pulses of fuel injection to more than one cylinder.
By momentarily up shifting the transmission to a maximum gear.

Question 7: What is the principal function of the OBD-II system?
The systemofOBD-IIgives access todata fromthe ECU which is also known as theenginecontrol unit andit offers the valuable informationsource if
troubleshootingissues in the vehicle. TheSAE J1979 standarddemonstrates the concept for requestingthe different diagnosticdata as well as the standards
parameters list whichmight be obtainable fromthe ECU.
Question 8: What is the purpose of an OBD-II monitor and give an example of what it can monitor?
OBD-II readiness monitors are easierbut powerful self check usual. Theygive views to theself diagnostics of car. The readiness purpose monitors is toself-test
the emission control systemofcar. On-boarddiagnostic (OBD)defines to theautomotive electronic systemthat gives vehicles self-diagnosis as well as exposure
abilities for maintenanceandrepairtechnicians.The OBD also provides technicians access to subsysteminformationfor the performancemonitoringas well as
analyzingrepair requirement.

Question 13: Complete the following statement about logical diagnosis using the following words?
Words: Available, Approach, Attention, Causes, Critical, Define, Diagnostic, Evident, Good, Happens,
Information, Isolate, Knowledge, Obvious, Original, Pinpoint, Present, Problem, Repair, Symptoms,
System, Test, Verify, Visual
When __diagnostic aids are not available or prove to be ineffective, most good technicians
conduct a good visual inspection and then take a logical __approach to finding the cause of the
problem. This relies on critical thinking skills as well as system knowledge . Logical
diagnosis follows these steps:
1 Gather _information about the problem. Find out when and where the problem
happens and what exactly happens.
2 Verify that the __ problem exists. Take the vehicle for a road__ test and try to
duplicate the problem, if possible.
3 Thoroughly__ define what the problem is and when it occurs. Pay strict attention
to the conditions present when the problem happens. Also, pay attention
to the entire vehicle; another problem may be __evident
to you that was not evident to the customer.
4 Research all__ available information to determine the possible_ cause of the
problem. Try to match the exact problem with a_ symptoms chart or think about what is
happening and match a or some components to the problem.
5 Separate the problem by testing. Narrow down the probable causes of the problem by
checking the obvious or easy-to-check items.
6 Continue testing to_ pinpoint the cause of the problem. Once you know where the problem
should be, test until you find it!
7 Locate and_ test the problem, then_ verify the repair. Never assume that your
Work solved the _ visual problem. Make sure the problem is history before returning it to
the customer.

Assessment Task 2: Job Safety Analysis
TASK SUMMARY:
This task is designed to develop your skills in identifying WH&S hazards/risks relating to the diagnosis of
complex system faults.
A Job Safety Analysis (JSA) is a procedure which helps integrate accepted workplace health and safety
principles and practices into a particular task or job to eliminate or reduce the risks or hazards to as low as is
reasonably practical.
Conducting a JSA will allow you to identify all potential hazards associated with a task(s) or job and to put in
place control measures to manage the risks to ensure the task or job is completed safely.
The benefits of conducting a Job Safety Analysis (JSA) include:
 Meet WHS standards
 keeping people safe ie. protect anybody working and visiting from injury or illness.
 complying with national safety regulations
 protecting the organisation from legal and financial penalties.
 Access to textbooks and other learning materials
 Access to workshop WHS policies, procedures and work instructions
 Access to a computer, printer and the Internet (where applicable)
 This assessment will be done in the automotive training workshop.
 Your assessor will provide you with the final due date for this assessment.
 A completed Job Safety Analysis Form

of 77
1. Consider the tasks/ job you will complete for any potential hazards.
2. Conduct a risk assessment (to determine the level of risk) of each hazard you have identified using the
RISK Matrix.
3. Record them on the JSA form (provided).
4. Continue to complete the JSA form.
5. Record the level of risk as: 12-25 (Extreme), 7-11 (Moderate to High), 4-6 (Low to Moderate), or 1-3
(Low) by using the RISK Matrix to determine the level of risk.
6. Once you have completed the JSA form, discuss the outcome of the hazard analysis, ie recommended
control measures with your assessor.
Any hazards identified will then need to be assessed to determine their level of risk and to put in place
control measures to manage the risk.
Assessment Task 2: Job Safety Analysis

information as possible from the customer. Are there aftermarket accessories on the vehicle? When
does the condition occur? Where does the condition occur? How long does the condition last? How
often does the condition occur?
2. Vehicle Operating as Designed: This condition exists when the vehicle is found to operate normally.
The condition described by the customer may be normal. Compare with another like vehicle that is
operating normally under the same conditions described by the customer.
3. Preliminary Checks: Conduct a thorough visual inspection. Review the service history. Detect unusual
sounds or odours.
4. Check for related Bulletins, Recalls and Preliminary Information.
5. Control Module Communication and DTC Check: Using a scan tool, perform the Vehicle DTC
Information function and verify that all vehicle control module communicates with the scan tool.
Record on the Job card the following information:
 Any control module that is not communicating
 Any DTC, including symptom byte, and the control module that has set the DTC.
Technician Note
Do not clear any DTCs unlessinstructedto do so by a diagnosticprocedure.If any DTC is Powertrainrelated,
selectCapture Info to store DTC and Freeze Frame/Failure Recordsto the Scan Tool.
6. For the DTC logged, describe how the system operates below.
7. What are the conditions for ‘Running’ the DTC?
8. What are the conditions for ‘Setting’ the DTC?
9. List the possible causes that could cause the above DTC to log?
10. Isolate the problem by testing. Narrow down the probable causes of the problem by following the
Pinpoint test as specified in the WSM for the DTC’s above.
Note your findings on the back of the Job Card
CAUTION!
Do not inserttest equipmentprobes (DMM etc.) into any connector or fuse block terminal. The diameter of
the test probes will deform most terminals. A deformed terminal will cause a poor connection, which will
resultin a system failure.Alwaysuse the ApprovedTerminal Release Tool Kit to probe terminals. Do not use
paper clips or other substitutes to probe terminals.
11. Document your test result on the back of the Job Card, and compare them to the vehicle WSM.
12. Report the fault. You must report your findings to the customer by filling in the Recommendations for
the repair of the vehicle on the back of the Job Card.
