Diagnostics is one of the most misunderstood processes in automotive repair. The perception is there is a magical “Diagnostic Machine” we attach to your vehicle and the solution to your problem is produced out of the “Machine”. In reality diagnostics is a procedure to systematically use test equipment and information systems to determine the cause of a vehicle’s ailment.

The testing tools, information systems, and technician knowledge requires a commitment to training and equipment expenditures. Glenwood Auto Service has made and continues to make that commitment.

Antilock Brake Systems (ABS)

Check Engine Light


“CHECK ENGINE LIGHT”, “SERVICE ENGINE SOON”, commonly referred to as a malfunction indicator light (MIL) by the manufacturer. These warning lights indicate that an error was logged in the computer system that controls a vehicle system. Severity of the problem is not always obvious to the driver. Errors that illuminate the MIL light can change the operation of the computer system. A fuel efficiency decline, unusual transmission operation, or component damage can be a result of inattention to the MIL light.

We take pride in our ability to offer complete diagnostic capability on all domestic and import vehicles.
