- (no calculation-based items — the core tasks ASE lists for this area.
- Road / Operational Test (4 of 50 — 7%) — confirm braking performance and that the truck does NOT pull, turn each SYMPTOM into a specific responsible COMPONENT, pull to one side when released = low front-tire pressure, brake.
How to use it in your final week
- Front-load Frame & Chassis — at 26 of the 50 scored questions it is about 43% of the test on its own, so if you master one section from the sheet, make it this one.
- Then work Engine Systems (12 of 50) — the sheet leads there with engine oil check.
- Then work Electrical & Electronics (12 of 50) — the sheet leads there with battery state of charge (open-circuit, at REST).
- Drill the reversal traps until they are reflex — the most commonly flipped one on this test is judging pushrod stroke WITHOUT identifying the chamber type.
- Read the sheet the morning of your appointment for a last pass on the memory hooks, then answer every one of the 60 questions — 10 are unscored research items and you are not told which.
