How are electronic parts tested?

Testing electronic parts requires precision and experience, and we take that responsibility seriously. At 603 Auto Salvage, we have specialized diagnostic tools that allow us to test modules, sensors, switches, alternators, starters, and other electronic components before listing them for sale.

Our technicians use multimeters, load testers, and OEM diagnostic scanners to verify functionality. Whenever possible, we test parts while they are still installed in the donor vehicle to ensure they communicate correctly with the vehicle’s computer systems. This is especially important for components such as engine control units (ECUs), transmission modules, and body control modules.

For parts that cannot be bench-tested, such as airbags or sealed sensors, we rely on a combination of visual inspection, code scanning, and compatibility verification. We check connectors, circuit boards, and terminals for corrosion or damage. Only clean, intact, and operational parts are approved for resale.

Each electronic part is labeled, cataloged, and stored in climate-controlled areas to prevent deterioration. We also provide customers with return support if a part doesn’t function as expected, provided it was installed according to proper procedures.

Electronics are one of the trickiest parts of modern vehicles, but we’ve built our reputation on handling them carefully and professionally. You can buy confidently knowing that every module or sensor from 603 Auto Salvage has been checked by skilled hands using the right equipment.
