About this exam

The AUR30320 Certificate III in Automotive Electrical Technology is an Australian vocational qualification reflecting the role of people who service, diagnose and repair electrical systems and components in vehicles within the automotive electrical service and repair industry. It suits apprentices and existing technicians who want a formal, nationally recognised credential for automotive electrical work, including light vehicle, heavy vehicle and emerging electric and hybrid technologies depending on the electives chosen.

The qualification requires 32 units: 21 core units plus 11 elective units. Core study builds foundation skills in workplace safety and environmental practice, electrical test equipment, soldering, circuit and wiring knowledge, lighting and harness installation, battery, charging, starting and ignition systems, engine management for spark and compression ignition engines, instruments and warning systems, electronic body management, diagnostic test strategies and engine servicing. Electives let candidates specialise in areas such as electric and hybrid vehicles, ADAS diagnostics and calibration, air conditioning, braking, steering and suspension electronics, network control systems or welding.

There are no entry requirements and no licensing, legislative or certification requirements apply to the qualification at the time of publication. Preparation should combine supervised workshop practice with theory revision of circuit principles, diagnostic strategies and safe work procedures. Confirm unit availability and training arrangements with your registered training provider, since elective offerings vary.

What you'll study

Common questions

About Cert III Auto Electrical preparation

How many units must I complete for this qualification?

You need 32 units in total: 21 core units plus 11 elective units. All 11 electives may come from the listed elective units, or up to 6 may be drawn from a Certificate II qualification or above in this Training Package or another endorsed Training Package or accredited course.

Are there any entry requirements?

No. The National Training Register lists entry requirements as nil, so you do not need prior qualifications or specified subjects to enrol. Individual training providers may still apply their own enrolment conditions, so check with your provider before committing.

Does this qualification license me to work as an auto electrician?

No licensing, legislative or certification requirements apply to this qualification at the time of publication. Licensing for electrical work is handled separately by state and territory regulators, so check your local requirements if you intend to perform regulated work.

What does the core study cover?

Core units cover safe and environmentally responsible work practices, electrical test equipment, soldering, automotive circuits and wiring, lighting and harness installation, batteries, charging, starting and ignition systems, spark and compression ignition engine management, instruments and warning systems, electronic body management, diagnostic test strategies and engine inspection and servicing.

Which electives are available?

The elective list is broad. It includes electric and hybrid vehicle units, ADAS knowledge, diagnosis, scanning and calibration, air conditioning and HVAC units, electric braking, steering and suspension electronics, network electronic control, dynamic control systems, heavy vehicle electronic systems, marine electrical systems, welding, technical guidance and quoting skills.

How should I order my study?

Start with the safety, environmental and electrical fundamentals units, then move to test equipment, circuits, soldering and wiring. Progress to batteries, charging, starting and ignition before tackling engine management, body management and diagnostic strategy units. Choose electives that match your workplace equipment and the vehicles you actually service.

What are common reasons candidates struggle?

Weak circuit theory and poor diagnostic discipline are frequent problems, along with unfamiliarity with wiring schematics and test equipment. Candidates also underestimate the engine management and electronic body management units. Practise reading wiring diagrams, measuring circuits and documenting diagnostic test strategies rather than memorising fault codes.

Has the qualification changed recently?

Yes. Release 5 added ADAS knowledge and ADAS diagnosis and repair units to the general electives, and replaced AURETR149 with AURETR249, which covers scanning and calibrating advanced driver assistance systems. Earlier releases also added and removed elective units, so confirm you are enrolled against the current release.

Can I get credit for units I already completed?

The packaging rules allow up to 6 units from a Certificate II qualification or above in this Training Package or another endorsed Training Package or accredited course. Electives must be relevant to the work environment, maintain AQF alignment, avoid duplicating outcomes and contribute to a valid vocational outcome. Your provider assesses credit.
