Mobile ADAS Calibration is best closed out with objective proof, and for a Hyundai i20 that proof is typically the pre-scan/post-scan record plus documented routine completion. A strong record shows what codes and module conditions existed before service, which calibration routines were performed, and whether any related faults remained afterward. Documentation should name the systems addressed—forward camera calibration, radar aiming/verification, steering angle initialization, sensor-fusion validation—so scope is explicit. Where possible, capture the scan-tool routine name and completed status to tie results to the correct workflow for that Hyundai i20 configuration. This evidence supports safety assurance, claim records, and future diagnostics. It establishes a baseline that can be referenced after later alignment, suspension changes, another windshield replacement, or repairs that affect sensor geometry. It also shows ADAS Calibration was performed as a necessary step after glass or front-end work rather than a discretionary add-on. Good documentation includes date/time, technician identification, method (static, dynamic, or both), and brief notes on verified prerequisites (level surface, tire pressures normalized, battery support used). If a dynamic drive was required, note general completion conditions. After documentation is generated, confirm warnings are off and features can be enabled; if completion isn’t possible on-site, document the limiting factor and recommended next step.
