What Are Auto Computer Diagnostics?

Modern vehicles rely on complex onboard computer systems to monitor engine performance, transmission operation, emissions systems, fuel delivery, sensors, and more.

When you bring your vehicle to Cassill Motors for computer diagnostics in Cedar Rapids, we:

  1. Connect your vehicle to advanced diagnostic scanning equipment
  2. Retrieve fault codes from onboard computers
  3. Analyze live performance data
  4. Interpret manufacturer-specific trouble codes
