AARC Automotive Parts Grading & Inventory 2 — Questions and Answers
Question 1: A used transmission has minor surface rust on the housing but all internal components are verified functional. What grade should it receive under ARA standards?
- Grade A
- Grade B (Correct answer)
- Grade C
- Scrap only
Correct answer: Grade B
Grade B indicates a part that is functional but has cosmetic flaws such as surface rust that do not affect performance.
Question 2: Which ARA grading designation indicates a part has been tested and certified to meet OEM performance specifications?
- Inspected
- Tested (Correct answer)
- Certified
- Guaranteed
Correct answer: Tested
The 'Tested' designation under ARA standards means the part has been functionally verified to operate within OEM specifications.
Question 3: When inventorying a hood with a repaired dent that is nearly invisible, which grade is most appropriate?
- Grade A
- Grade B+
- Grade B (Correct answer)
- Grade C
Correct answer: Grade B
Grade B is assigned to body panels that have been repaired or have minor imperfections detectable upon close inspection.
Question 4: An engine with an unknown mileage history and no test results should be listed in the inventory system with what notation?
- Grade A — assume good
- Untested — mileage unknown (Correct answer)
- Grade C by default
- Do not list until tested
Correct answer: Untested — mileage unknown
ARA standards require accurate disclosure; unknown mileage and untested status must be explicitly noted to avoid misrepresentation.
Question 5: Which factor is MOST critical when grading a used airbag module for resale?
- Exterior housing condition
- Whether the airbag has ever deployed (Correct answer)
- Connector pin corrosion
- Storage temperature history
Correct answer: Whether the airbag has ever deployed
A deployed airbag module cannot be resold as functional because the inflator is single-use and the module is spent.
Question 6: What is the primary purpose of using standardized ARA part grades in an inventory management system?
- To comply with EPA hazardous waste rules
- To enable consistent pricing and buyer expectations nationwide (Correct answer)
- To track warranty claims by VIN
- To satisfy state smog inspection requirements
Correct answer: To enable consistent pricing and buyer expectations nationwide
Standardized grades create a common language so buyers at any recycler understand the condition they are purchasing without physically inspecting every part.
Question 7: A catalytic converter is removed from a vehicle with a salvage title due to flood damage. Internal inspection shows no physical damage. How should it be graded?
- Grade A — no visible damage
- Grade B — flood history noted (Correct answer)
- Scrap — flood vehicles always disqualify converters
- Cannot grade without lab analysis
Correct answer: Grade B — flood history noted
Flood history is a material condition that must be disclosed; Grade B with flood notation reflects functional potential with a known risk factor.
