Why Is an ADAS Warning On After Windshield or Collision Repair?
An ADAS warning after windshield, bumper, alignment, or collision repair may mean a camera or radar cannot operate correctly, a sensor was moved or disconnected, calibration is required or incomplete, mounting geometry changed, or an electrical fault is present. A successful scan alone does not confirm that every required repair procedure was completed.
What Summit evaluates
Repair events that can affect the system.
Windshield replacement
Glass, camera mounting, removal, reconnection, and manufacturer procedures can affect operation.
Bumper or grille work
Radar position, brackets, covers, wiring, and nearby repairs can change performance.
Collision or structural repair
Vehicle geometry and sensor reference points may no longer match learned values.
Alignment or ride height
Changes in vehicle direction or stance can affect where cameras and radar are aimed.
Calibration incomplete
The wrong procedure, environment, setup, prerequisites, or unresolved fault can prevent completion.
Wiring or communication
Damage, connectors, custom coax, modules, power, grounds, and networks may require diagnosis.
Why diagnosis matters
A code is the beginning of the investigation.
Summit reviews the repair event, applicable manufacturer requirements, mounting and wiring condition, scan information, calibration history, alignment and setup prerequisites, and the complete electronic system.
