A current guide to the ASE G1 format, 2026 maintenance and light repair blueprint, Prometric test-center delivery, engine, drivetrain, suspension, brakes, electrical, and HVAC basics.
ASE G1 is designed for maintenance and light repair technicians rather than full A-series master status. It covers the common inspection, service, and light repair work that shows up every day in entry-level and general-service roles.
Use these official structure points to keep G1 prep aligned with the 2026 ASE Auto Maintenance & Light Repair study guide.
G1 identifies Auto Maintenance and Light Repair technicians who can perform common maintenance and light repair tasks.
ASE lists the G1 certification appointment as 55 total questions, 45 scored questions, and 90 minutes.
ASE certification requires passing the test and documenting relevant work experience; vocational training may count toward part of the requirement.
The G1 recertification test has 28 questions and a 45-minute testing time.
Suspension and steering is the largest specification area at 13 questions, or 24%.
The blueprint also covers engine systems, brakes, electrical, manual drivetrains, automatic transmissions, and HVAC.
G1 focuses on day-to-day service tasks: verifying concerns, using service information, performing inspections, changing oil, checking cooling systems, replacing belts and hoses, retrieving DTCs, servicing filters, and recognizing when more diagnosis is needed.
Suspension and steering plus brakes make up the largest share of the specification table, so candidates should practice tire wear, wheel and tire service, steering and suspension inspection, brake measurements, brake fluid, and routine brake hardware service.
Electrical questions are practical: batteries, starting checks, lighting, wipers, warning indicators, fuses, basic circuits, and recognizing when a system needs deeper diagnosis.
G1 does not replace the A1-A8 Master Automobile Technician path. It is a focused credential for maintenance and light repair roles and can be a sensible first ASE professional certification.

ASE G1 Auto Maintenance and Light Repair identifies technicians who can perform common maintenance and light repair tasks. ASE's 2026 G1 study guide lists the certification appointment as 55 total questions with 45 scored questions and a 90-minute testing time; the G1 recertification test has 28 questions and 45 minutes. ASE certification requires passing the test and documenting relevant work experience, with appropriate vocational training able to count toward part of the requirement. The G1 specification table organizes preparation across Engine Systems (9 questions, 16%), Automatic Transmission/Transaxle (4, 7%), Manual Drive Train and Axles (6, 11%), Suspension and Steering (13, 24%), Brakes (11, 20%), Electrical (8, 15%), and Heating, Ventilation, and Air Conditioning (4, 7%). Preparation should emphasize oil and filter service, cooling checks, belts, hoses, air induction, basic DTC retrieval, spark plugs, EVAP inspection, DEF checks, transmission fluid checks, CV joints, tires, steering and suspension inspection, brake service, battery and starting checks, lighting, wipers, and HVAC filters or basic performance checks.
ASE lists the 2026 G1 certification appointment as 55 total questions, with 45 scored questions.
The G1 certification testing time is 90 minutes.
The G1 specification covers engine systems, automatic transmission/transaxle, manual drive train and axles, suspension and steering, brakes, electrical, and heating, ventilation, and air conditioning.
No. Master Automobile Technician status is based on A1 through A8 plus the experience requirement; G1 is a separate maintenance and light repair certification.
Yes. ASE says the G1 test includes a Leer en espanol button for side-by-side Spanish and English question and answer rendering, plus the ASE Spanish/English glossary.
Anchor study time to suspension and steering, brakes, engine systems, electrical, drivetrains, transmissions, and HVAC in their official G1 weights.
Practice oil service, coolant service, belts, hoses, filters, DEF, tire inspection, battery checks, brake measurements, and basic DTC retrieval.
Study spark plugs, secondary ignition inspection, transmission fluid checks, CV joints, suspension components, wheel service, brake hardware, lighting, wipers, and cabin filters.
Run 55-question timed practice blocks in 90 minutes and revisit flagged inspection or specification questions before submitting.
Use the guide to self-serve, or talk to a coordinator if you need help mapping timelines, official requirements, or troubleshooting day-of logistics.
