Options for diagnosing faults may include:
continuity testing
insulation testing
isolation and repair to located faults
replacement of blown fuses or circuit breakers
replacement of damaged connectors or terminals
visual inspection and evaluation of components.
Inappropriate testing procedures may include:
intrusive testing (which must not be performed as it is not a recommended test and repair method), which includes:
back probing terminals and connectors and fuse holders with inappropriate test probes
probing terminal and connectors with inappropriate test probes
pushing sharp probes and objects into wiring insulation.
Faults may include:
open circuits
short circuits
high resistance circuits
damaged insulation
frayed wires
burnt wiring
water and moisture ingress
connector damage
terminal damage
diagnosis trouble codes (DTC) being set.
Reprogramming options may include:
service programming system (SPS)
manufacturer programming code and relearn procedures
original equipment manufacturer (OEM) specific programming code.
Post-repair testing may include:
validating effectiveness of the replacement or repair action
confirming that reported fault has been rectified
confirming that no other faults are present as a result of the replacement and the reprogram or repair action.

EVIDENCE GUIDE
The evidence guide provides advice on assessment and must be read in conjunction with the Performance Criteria, required Skills and Knowledge, the Range Statement and the Assessment Guidelines for the Training Package.
Overview of assessment

Critical aspects for assessment and evidence required to demonstrate competency in this unit
The evidence required to demonstrate competency in this unit must be relevant to workplace operations and satisfy all of the requirements of the performance criteria and required skills and knowledge.
A person who demonstrates competency in this unit must be able to:
observe safety procedures and requirements
select methods and techniques appropriate to the circumstances
complete preparatory activity in a systematic manner
remove and replace a minimum of four units and assemblies to workplace, manufacturer and component supplier requirements, including:
one supplementary restraint system module
one body control module
one engine or powertrain control module
complete final functional test to specification
present vehicle and equipment in a condition that complies with workplace requirements.
Context of, and specific resources for assessment
Competency is to be assessed in the workplace or a simulated workplace environment that accurately reflects performance in a real workplace setting.
Assessment is to occur:
using standard workplace practices and procedures
following safety requirements
applying environmental constraints.
Assessment is to comply with relevant:
regulatory requirements
Australian standards
industry codes of practice.
The following resources must be made available for the assessment of this unit:
workplace location or simulated workplace
material relevant to removing and replacing electrical and electronic units and assemblies
equipment, and hand and power tools appropriate to removing and replacing electrical and electronic units and assemblies
specifications and work instructions.
Method of assessment
Assessment must satisfy the endorsed Assessment Guidelines of this Training Package.
Assessment methods must confirm consistency and accuracy of performance (over time and in a range of workplace relevant contexts) together with the application of required skills and knowledge.
Assessment methods must be by direct observation of tasks and include questioning on required skills and knowledge to ensure correct interpretation and application.
Competence in this unit may be assessed in conjunction with other units which together form part of a holistic work role.
Where applicable, reasonable adjustment must be made to work environments and training situations to accommodate the needs of diverse clients.
Assessment processes and techniques must be culturally sensitive and appropriate to the language, literacy and numeracy capacity of the candidate and the work being performed.
