Diagnostic Services

Modern Vehicles are equipped with on-board diagnostic abilities to monitor the performance of critical systems.  Computers in your vehicle will be able to detect the symptoms of a problem and illuminate a warning light on the dash to indicate that there is a problem. You may see a “Check engine” light or “Service Engine Soon” light. This light will indicate when there is a problem with the engine, transmission, or emission control system. You may see an “ABS” light, this will indicate a problem with the Anti Lock Brake System. Some vehicles will also have a warning light for traction control or stability control. These on-board diagnostic systems will often provide a trouble code to indicate the specific system that requires diagnosis.

What Are Diagnostic Services?

Diagnostics are an important step in determining a needed repair for your vehicle. A technician will use information obtained from the customer interview, as well as trouble codes provided by the vehicle to determine what system is not functioning properly. An example of a trouble code might be: P0300. This code indicates a random misfire on all cylinders. There could be a variety of causes for this issue. The technician will inspect and test components related to maintaining the correct fuel and air mix inside the cylinders as well as the ignition system to determine why the vehicle is not able to consistently ignite a fuel/air mixture. Diagnostics conducted by a trained professional will ensure that the correct repair is done the first time. Trying to repair a vehicle without first conducting a diagnostic often results in wasted time and money replacing parts that aren’t part of the problem.

What Does the Check Engine Light Indicate?

The Check Engine Light is a visual indication that your vehicle has detected a problem with one of the systems that is monitored by your vehicle’s on board computer. The computer stores a code that can be retrieved using a diagnostic scan tool. In some cases the computer may also have stored freeze frame data. This data captures a snapshot of the vehicle conditions when a problem is detected. This will aid a technician when he or she is conditioning a diagnostic to determine the root caust of the trouble code. 

Is It Always a Sign of Major Engine Repair?

The check engine light does not always indicate that there is a serious problem. You may not even notice any difference in the operation of your vehicle. For example, you may have a leak in your air induction system allowing unmetered air into the engine, and producing a lean condition. This means that there is too much air for the amount of fuel that your vehicle is injecting to the cylinder. Today’s vehicles have the ability to compensate for a problem like this by adding more fuel to keep the engine running well. While you may not have noticed a change in performance, your fuel economy could be suffering. 

If your check engine light comes on, having a diagnostic done soon is the best option. You may avoid a problem becoming worse by addressing the problem early on. Some vehicle owners will choose not to address the check engine light unless they do notice a problem with the performance of the vehicle.  The problem with this choice is that there may now be multiple trouble codes. It can now be difficult to determine exactly what the cause of your performance issues is and increase the cost and difficulty of a diagnostic. 

What does a flashing check engine light mean?

A flashing check engine light indicates a serious problem that will likely cause more damage to the engine if it is not addressed immediately. The best choice is to find a safe place to pull over and have your vehicle towed to a repair facility capable of performing diagnostics. 

Can I do a diagnostic myself at home?

You can now purchase an OBD II scanner at a parts store or online. These scanners may allow you to retrieve trouble codes from your vehicle. Most entry level scanners will however not allow you to view codes from all systems. The Airbag and Transmission control modules will most likely not be accessible with an entry level scanner. It is common for your everyday vehicle owner to misinterpret trouble codes, and replace parts that are not the cause of the problem. One of the most common examples of this is oxygen sensors. The oxygen sensors monitor the amount of fuel in the exhaust leaving the engine. While a trouble code may be present due to a faulty sensor, it is just as common for another problem to be having an impact on the amount of fuel in the exhaust. This can generate the same code as a faulty sensor. 

So, while you may sometimes get lucky, the only sure way to fix your vehicle right the first time is to have a trained technician perform a diagnostic.
