Proof and documentation close out mobile ADAS Calibration on a Mercedes-Benz Cls-Class, providing objective evidence that required routines were completed. A strong closeout includes a post-scan report showing which modules were checked, which DTCs existed before service, and whether any calibration-related faults remain afterward. It should also list the completed routines—forward camera calibration, radar aiming/verification, steering angle initialization, or sensor-fusion validation—so scope is clear. When possible, record the scan-tool routine name and completion status for the specific Mercedes-Benz Cls-Class configuration. These records matter beyond today’s visit. They establish a “known good” baseline that helps after later alignment work, suspension changes, another windshield replacement, or additional repairs that affect sensor geometry. They also support claims by showing ADAS Calibration was performed as a required step after glass or front-end work, not simply by clearing codes. Good documentation includes date/time, technician identification, method used (static, dynamic, or both), and brief notes on on-site prerequisites (level surface, tire pressures normalized, battery support used). If a dynamic drive was required, noting general completion conditions can explain why the routine passed. Finally, confirm warnings are off and features can be enabled; if completion isn’t possible, document the limiting factor and the next-step recommendation.
