A current guide to the ASE A6 format, 50 scored-question blueprint, Prometric test-center delivery, electrical diagnosis, batteries, starting, charging, lighting, instrument cluster, and body electrical objectives.
ASE A6 is a diagnosis-heavy electrical test. It expects technicians to use measurements, wiring diagrams, scan data, and circuit logic to find faults rather than guessing at parts.
Use these official structure points to keep A6 prep aligned with the ASE Automobile & Light Truck study guide.
A6 is part of ASE Automobile & Light Truck Certification Tests for cars, SUVs, and light-duty trucks up to Class 3.
The A6 certification appointment has 60 questions in 1 hour 30 minutes, including 50 scored questions plus unscored research questions.
ASE certification requires passing the test and submitting appropriate hands-on work experience.
ASE credentials are valid for five years; the A6 recertification test is shorter at 25 questions and 45 minutes.
General electrical/electronic system diagnosis is 13 scored questions, or 26% of the test.
Body electrical is 22%, battery/starting is 18%, lighting and instrument systems are 12% each, and charging is 10%.
A6 gives the largest weight to general electrical diagnosis, so candidates should practice voltage drop, current, resistance, continuity, waveform interpretation, scan data, DTCs, schematic reading, shorts, opens, grounds, and parasitic draw.
Battery and starting questions require state-of-charge tests, load or capacitance tests, memory preservation, jump-start procedures, starter current draw, voltage drop tests, relays, solenoids, and slow-crank diagnosis. Charging questions require output tests and belt or pulley inspection.
Body electrical systems are a large domain and can include power windows, locks, seats, mirrors, wipers, modules, switches, relays, harnesses, data networks, and initialization procedures.
A6 allows 90 minutes, but electrical scenarios can consume time. Practice deciding what measurement comes next and flag circuit-trace questions that need a second pass.

ASE A6 Electrical/Electronic Systems is part of the Automobile & Light Truck Certification Tests for technicians who diagnose, service, and repair cars, SUVs, and light-duty trucks up to Class 3. ASE lists A6 as 50 scored questions, with 60 total questions in the certification appointment because certification tests include additional unscored research questions; the testing time is 1 hour 30 minutes. Certification also requires appropriate hands-on work experience, and credentials must be renewed every five years. The official A6 blueprint covers General Electrical/Electronic System Diagnosis (13 scored questions, 26%), Battery and Starting System Diagnosis and Repair (9, 18%), Charging System Diagnosis and Repair (5, 10%), Lighting Systems Diagnosis and Repair (6, 12%), Instrument Cluster and Driver Information Systems Diagnosis and Repair (6, 12%), and Body Electrical Systems Diagnosis and Repair (11, 22%). Preparation should emphasize voltage drop, current flow, resistance, continuity, waveforms, scan tool data, DTCs, shorts, opens, parasitic draw, schematics, data bus communication, module programming, batteries, starters, charging output, lighting, warning indicators, gauges, power accessories, locks, windows, wipers, mirrors, seats, and networked body controls.
ASE lists A6 as 50 scored questions, while the certification appointment contains 60 total questions because additional unscored research questions are included.
The A6 certification testing time is 1 hour 30 minutes.
The scored blueprint covers general electrical/electronic diagnosis, battery and starting systems, charging systems, lighting systems, instrument cluster and driver information systems, and body electrical systems.
General electrical/electronic diagnosis is the largest domain at 26% of the scored test.
Yes. Passing A1 through A8 and meeting the experience requirement earns ASE Master Automobile Technician status. A6 is also a prerequisite path for some advanced ASE credentials.
Anchor study time to the six A6 domains, starting with the 26% general electrical diagnosis section.
Practice voltage drop, current draw, continuity, resistance, parasitic draw, charging output, starter draw, and waveform interpretation.
Work through fuse, relay, switch, ground, module, connector, and data bus paths until fault location becomes systematic.
Run 60-question timed practice blocks in 90 minutes and reserve time for wiring-diagram questions.
Use the guide to self-serve, or talk to a coordinator if you need help mapping timelines, official requirements, or troubleshooting day-of logistics.
