CAADE Damage Analysis and Inspection 5 — Questions and Answers
Question 1: A vehicle appraiser notes that the trunk lid closes flush on the right side but sits slightly proud on the left. Without other damage indicators, what is the most appropriate next step?
- Document as factory variance and move on
- Perform diagonal measurements on the rear aperture and inspect the rear frame rails (Correct answer)
- Adjust the trunk lid strikers only
- Check trunk lid hinge bolts for looseness
Correct answer: Perform diagonal measurements on the rear aperture and inspect the rear frame rails
Trunk lid misalignment can indicate rear structure deformation; diagonal measurements and frame rail inspection are needed to rule out underlying structural damage.
Question 2: When an appraiser identifies corrosion perforation on a structural rail, the repair method that restores full structural integrity is:
- Applying rust converter and seam sealer over the affected area
- Sectioning and replacing the damaged rail portion with OEM or equivalent material (Correct answer)
- Grinding the rust flush and applying a protective coating
- Using weld-through primer alone to bridge the perforated area
Correct answer: Sectioning and replacing the damaged rail portion with OEM or equivalent material
Structural perforations require sectioning and replacement of the affected rail section to restore the component's designed load-carrying capacity.
Question 3: During an inspection, an appraiser finds that the VIN plate on the dashboard is slightly misaligned and shows evidence of being re-riveted. This finding most critically raises concern about:
- Factory quality control issues
- Possible VIN tampering or title fraud (Correct answer)
- A dealer-installed GPS tracker
- Water intrusion around the windshield
Correct answer: Possible VIN tampering or title fraud
A re-riveted or disturbed VIN plate is a major red flag for potential VIN tampering, which may indicate a stolen vehicle or title fraud.
Question 4: What is the correct sequence for performing a complete vehicle damage inspection?
- Interior → Exterior → Underbody → Mechanical
- Walk-around exterior → Open panels → Interior → Underbody → Mechanical/Operational (Correct answer)
- Mechanical → Underbody → Exterior → Interior
- Underbody → Interior → Exterior → Operational
Correct answer: Walk-around exterior → Open panels → Interior → Underbody → Mechanical/Operational
The industry-standard sequence begins with an exterior walk-around, then opened panels (hood/trunk/doors), followed by interior, underbody, and finally mechanical and operational checks.
Question 5: A vehicle's ADAS camera system (forward collision warning) requires recalibration after a collision primarily because:
- The camera lens may have been scratched
- Front-end repairs can shift the camera mounting angle, affecting its field of view and detection zone (Correct answer)
- Collision impact always corrupts the camera's software
- Insurance companies require it regardless of repair scope
Correct answer: Front-end repairs can shift the camera mounting angle, affecting its field of view and detection zone
Even minor front-end repairs can alter the mounting angle of ADAS cameras, shifting their calibrated detection zone and requiring static or dynamic recalibration.
Question 6: When evaluating a vehicle with suspected prior airbag deployment, finding white powder residue in the dashboard seams is indicative of:
- A cleaning product residue from detailing
- Sodium azide or similar propellant byproduct from airbag deployment (Correct answer)
- Deteriorating foam padding
- Insulation material breakdown
Correct answer: Sodium azide or similar propellant byproduct from airbag deployment
White powder residue in dash and interior seams is a classic sign of airbag deployment, resulting from the propellant (historically sodium azide or modern alternatives) and bag lubricant released during inflation.
Question 7: Which condition would MOST likely cause a vehicle to fail a structural integrity assessment after a collision repair?
- Minor paint color mismatch on a quarter panel
- Repair performed with heat on a high-strength steel (HSS) rail without replacement (Correct answer)
- Non-OEM trim clips used during reassembly
- Slight variation in door gap width within 2mm of specification
Correct answer: Repair performed with heat on a high-strength steel (HSS) rail without replacement
Applying heat to high-strength steel (HSS) reduces its tensile strength, compromising the designed crash performance; OEM repair procedures typically require replacement, not heat repair.
