Computer Diagnostics

Today's vehicles are manufactured with complex inter-related systems. Computers continuously monitor and store information concerning the performance of these systems. When the computer determines that one or more of these systems is not operating properly, a signal is sent to turn on warning lights to let you know something is wrong.

Dash Warning Lights

While warning lights can illuminate and the car still seems to be driving just fine, ignoring these lights can lead to serious mechanical issues, such as engine damage, component failure or entire system failure. In some instances, this can be a safety hazard.

At Roy Brothers Tire and Auto, we have the tools, training and technology to handle diagnostic issues. We will perform an onboard computer system analysis in order to retrieve the computer codes, computer software version numbers, freeze frame data, and critical sensor data. From this information, we can determine which system has set off the warning light and investigate the issue at the source.

System Specification Testing

Despite the lack of dash warning lights, your vehicle's systems could be under-performing. Roy Brothers will tap into your car's computer and run tests determine if your systems meet proper specifications. These tests may include an analysis of:

  • Emissions system
  • Backpressure and vacuum

  • Electrical engine timing
  • Mechanical engine timing
  • Ignition system

Come see us at Roy Brothers for a computer diagnostic test and we'll see that your vehicle is running at its best!
