What this repair actually is.
Before major repair or collision work, a technician scans every computer module in the vehicle and records all stored trouble codes and system statuses. This creates a documented baseline — pre-existing faults are identified up front, insurers and warranty claims get the paperwork they require, and the repair plan accounts for everything the vehicle is reporting.
How you can tell.
- Vehicle headed in for major or collision repair
- Insurance company requires scan documentation
- Multiple warning lights before repair
- Want a documented baseline before work starts
- Buying repairs on a car with unknown history
Without a baseline scan, pre-existing faults surface mid-repair — causing disputes, delays, and repairs that miss related problems.
