ASE B6 Damage Analysis & Estimating common mistakes
ASE B6 Damage Analysis & Estimating · Understand the traps and how to avoid them.
Writing an estimate line for a damaged part without first confirming the vehicle's VIN, production date, and trim/option content, then pricing or ordering the wrong variant.
Candidates treat the estimate as a pure visual exercise and skip the identification step, assuming all trims of a model share the same panels, lamps, and bumper covers.
What to do instead
Establish a habit of documenting VIN decode, door-jamb labels, and RPO/option codes before any part is priced; verify part numbers against VIN-filtered catalog data and note supersessions.
Judging a panel as repairable or replaceable from appearance alone without measuring or checking for backing damage, creasing, or stretched metal.
Candidates rely on the visual impression of dent size and miss that location, crease sharpness, panel curvature, and access for tools drive the repair/replace call more than area.
What to do instead
Apply explicit criteria: crease depth and sharpness, proximity to body lines and edges, double-wall or adhesive-bonded construction, and whether the back side is accessible; state the criteria in the estimate justification.
Missing hidden or consequential damage behind the struck panel (inner wheelhouse, apron, radiator support, bumper reinforcement, absorbers) and writing only the outer cosmetic parts.
Candidates estimate what is directly visible and do not mentally trace the load path or anticipate what must be removed to inspect.
What to do instead
For every impact, list the load path and the components that must be disassembled to inspect; include an inspection/teardown operation and flag potential hidden damage as a supplement pending teardown.
Treating a unitized body like a full frame and describing 'frame damage' or recommending frame straightening on a unibody vehicle.
Candidates conflate the two construction types and do not distinguish structural rails, aprons, and strut towers from a ladder frame.
What to do instead
Identify construction type first (body-over-frame vs. unitized), then use the correct terminology and measuring approach; know that unibody structural repair centers on rails, aprons, and control-point dimensions.
Failing to specify measuring or setup time on a structural pull, or omitting the pre/post measuring and documentation steps.
Candidates think of the pull itself as the whole job and forget that setup, anchoring, measuring, and documentation are separate billable operations.
What to do instead
Build the structural line item as setup/anchoring, pre-repair measure, pull, post-repair measure, and document each with before/after readings; verify against the vehicle's dimensional spec sheet.
Overlooking mechanical, electrical, and interior damage that accompanies a body hit (cooling pack, sensors, wiring, airbag components, seatbelts, trim clips).
Candidates focus on sheet metal and do not walk the adjacent systems or check for diagnostic scan requirements after an impact.
What to do instead
Perform a systematic sweep of adjacent systems on every estimate: cooling/condenser, lamps and sensors, harness routing, restraint components, and interior trim fasteners; include scan tool diagnostic time where required.
Choosing replace when repair is the correct and more economical operation, or vice versa, without weighing labor, materials, and part cost together.
Candidates compare only part price to labor rate and ignore refinish materials, corrosion protection, blend time, and the labor hours embedded in either path.
What to do instead
Do a side-by-side comparison of total repair cost (labor + refinish + materials + corrosion protection) against replace cost (part + R&I + refinish + blend); document the rationale on the estimate.
Omitting required refinish operations such as blending adjacent panels, edge and jamb painting, texture matching, or corrosion protection on replaced panels.
Candidates list paint as a single line and do not decompose it into prep, sealer, base, clear, blend, and protective coatings.
What to do instead
Itemize refinish by panel and operation; explicitly include blend panels, jambs and edges, texture/gravel guard, and OEM-required cavity wax or seam sealer on structural and panel replacements.
Failing to recognize and document a supplement when teardown reveals additional damage, or writing a supplement without referencing the original estimate line.
Candidates treat the first estimate as final and do not understand the supplement workflow, photo documentation, or the need to tie new lines to the original repair order.
What to do instead
After teardown, compare found damage to the original estimate, add supplement lines with photos and part numbers, reference the original line items, and obtain authorization before proceeding.
Mishandling total-loss math or customer communication, such as comparing repair cost to purchase price instead of actual cash value, or failing to explain the valuation and options clearly.
Candidates confuse market value, ACV, salvage value, and repair cost, and they deliver the total-loss decision without explaining the basis or the customer's options.
What to do instead
Compute and explain the total-loss threshold using ACV, repair cost, and salvage value; present the valuation method, the numbers, and the customer's choices (repair, settle, retain salvage where allowed) in plain language and document the conversation.
