Repair events and calibration decisions
A repair event starts a vehicle-specific research and inspection decision, not an automatic one-size-fits-all calibration.
Record the VIN, fitted ADAS options, repair location, removed/installed components, customer complaint and any relevant damage. Then find the current manufacturer information that applies to this system and event. The procedure may call for inspection, adjustments, diagnostics, programming, calibration, multiple operations, or no calibration for the particular action.

Choose an event. Explain the mechanism first, then decide what evidence a technician needs.
Wheel alignment and vehicle reference geometry
An alignment adjustment can change the reference used by a camera, radar or steering-related assistance system.
Thrust direction, wheel alignment and steering reference are related but not interchangeable. Camera or radar mounting may use manufacturer-defined vehicle datums. A vehicle can drive with an apparently centered steering wheel and still have an alignment or reference issue that matters to a specific ADAS procedure.
Inspect tire and suspension condition, ride height and alignment per the relevant repair and calibration procedures.
Determine whether steering angle reference, yaw-related calibration or other functions require checks or additional steps for this specific vehicle.

Windshield and forward-camera service
Glass is part of the optical environment for many forward-looking camera systems.
For equipped vehicles, a windshield replacement can change the relationship among the camera, mount, glass and roadway scene. The appropriate response depends on the actual camera system, glass specification, installation and manufacturer instructions. Other glass-related actions may have different requirements.

Collision and body repair
A cosmetic-looking impact can require investigating sensor, bracket, mounting and body reference integrity.
Document impact location, structural repairs, panel replacement, sensor and mount removal, grille/bumper materials, hidden damage, harness condition and repair method. A sensor may communicate normally while physically mispositioned. Conversely, the lack of a warning lamp does not establish that no ADAS inspection is required.

Suspension, bumper, lighting and related service
ADAS-related inspection may extend beyond direct camera or radar replacement.
Some sensor or reference requirements can be affected by suspension height changes, wheel/tire changes, steering component service, bumper or grille replacement, sensor coverings, mirror-mounted components, harness work, module programming or an altered vehicle configuration. Whether a given action triggers a required operation is model-, system- and procedure-dependent.
| Service event | Physical or electronic issue to investigate | Research question |
|---|---|---|
| Suspension/ride height | Relative sensor height and orientation, steering/vehicle geometry | Which checks and calibration steps apply after this exact repair? |
| Front bumper/grille | Radar mounting, bumper materials, sensor windows, wiring | Are the approved parts, mounting and recalibration requirements satisfied? |
| Module/sensor change | Compatibility, programming, identity, installation and aiming | Does the OEM require configuration, calibration, verification or additional work? |
| Mirror/trim/glass | Camera/mount installation and clear optical path | What applies to the equipped camera system and repaired component? |
Build an evidence-based repair plan
Different repairs on the same vehicle may lead to different service paths.
A defensible plan distinguishes what happened, what was observed, what the manufacturer requires, what was performed, and what remains unresolved. If a procedure or compatible equipment is unavailable, document the limitation and arrange a qualified referral rather than inventing a substitute.
Interactive repair-plan simulator
Illustrative scenario: a vehicle with forward camera and front radar arrives after glass service and minor front-end damage. The VIN-specific procedure has not yet been retrieved. Choose an action at each stage; an incorrect choice explains the issue and lets you reconsider.
Handoff, verification and accurate documentation
Complete service means recording both the evidence and the limits of what was done.
Record VIN/configuration, work and replaced parts, relevant inspection/measurement findings, applicable procedure reference and revision/date when available, tool and target identification when applicable, before/after DTC evidence, actual routine results and required post-checks. Separate tool-generated completion indicators from independent verification. If a system remains not ready, uncalibrated or not verified, say so clearly and follow appropriate shop/customer escalation procedures.
Documentation decision
The scan tool displays “calibration completed,” but an OEM-required post-check is still outstanding. Which statement belongs on the work order?
