Check Engine Light Diagnostics In Auburn, MA

One of the most frustrating things for a vehicle owner is seeing a lit check engine light on their dashboard. When this light comes on, it signifies that there is an engine, emissions, fuel system, or even a transmission-related issue where it is no longer operating within its specific design parameters. If the Check Engine Light is flashing, the vehicle should not be driven. If the light is illuminated it will also fail the Massachusetts State Inspection and receive a black “R” instead of a passing.

Our Approach To Diagnostics

Contrary to what most believe, there is not really an all-knowing computer that you simply “hook up” to the vehicle and it determines what needs to be repaired. The OBDII (On Board Diagnostic 2) link connects to a series of electronic modules that power and monitor the many systems of the vehicle. A diagnostic scan tool can retrieve a code or number of codes that signal interruptions of electrical values. These values are sequenced or “coded” to individual systems. While there are many “codes” that can routinely result in certain repairs, the code does not determine the fix. These values need to be understood in both cause and effect and a professionally trained technician knows both how and what to test without just replacing parts. Many consumers have developed a fear of paying for diagnostic time because they feel it is not a proactive approach to their problem, but neither is replacing unnecessary parts. However, the problem is that a vehicle not operating correctly when the light is on, and that is a concern for the customer and the shop they chose to fix the vehicle as efficiently and accurately as possible. When it comes to diagnosing, we recognize that it is not a one size fits all, so we offer both “Minor” and “Major” Diagnostic Services that are relative to the anticipated time needed to test the system for an accurate repair. In the event of multiple system faults, more time or tests may be necessary and that would be discussed with the customer ahead of time. When it comes to time/labor, or parts- you will never spend money that you do not authorize first.
