This type of car diagnostic tool like the OxGord CAN OBD II scanner allow for the retrieval of diagnostic trouble codes when the check engine light is illuminated. Having a diagnostic trouble code is very useful since it will give a direction of where to go in the diagnostic procedure. However, just having the code is not all of the information needed to start moving on the correct path towards diagnosing a vehicle. Having a description of what the code means is extremely important. There are many scan tools on the market. Some scan tools simply give the code with no other description. There are many different codes that can be set for an OBD II equipped vehicle. Even professionals will not know what every code means. Having a scan tool that will not only give the code, but also the description is very valuable. Without the description of the code it can be very difficult to know where the process of diagnosis starts. One code can be affected by multiple systems that are equipped on the vehicle. The code given does not necessarily give the consumer the root cause of the issue. Without the description of the code there is no way to know what course of action needs to be taken in the diagnostic procedure.
There is one very important step that needs to be taken after any repair for a check engine light is performed. Clearing the diagnostic trouble code needs to be done to ensure that the vehicle is repaired correctly. If the code is not cleared then the check engine light will continue to be illuminated even though the repair was made. This can also be useful when attempting to diagnose a vehicle. In some situations, there will be multiple codes stored in a vehicle’s computer system. When there are multiple codes it can be difficult to determine the root cause of all the codes. Some codes may even have been set because of a different code that is also stored. When this occurs it could be beneficial to start fresh. Vehicle computers use monitors to determine if there is an issue with a vehicle. These monitors run tests while the vehicle is running. When clearing diagnostic trouble codes these monitors are also reset. If there are multiple codes stored in the vehicles computer the next diagnostic step may be to clear the trouble codes, perform a road test with the vehicle, and see which codes return. This will show which codes are current, and constant failures. The OxGord Can OBD II scanner will give access to the vehicle’s computer so these trouble codes can be cleared, and the system can start fresh.
