The much hyped malfunction indicator MIL is a highly developed security measure for protecting the drivers. In most cases, it is referred as the check engine light indicator and usually informs the driver of potential for harm. OBD 2 diagnostic tools are the only known devices with the capacity for resetting this unique area.
Older car models were known to be compliant with the OBD2 software control system. However, with much development in automobile industry, the use of the power train control model (PCM) which is commonly known as the electronic engine management system has taken root.
Despite the different mix up’s in how it is called in Europe as electronic control unit and the normal (EMS) known to many, the functions are just the same. The options just give you some fall back as follows;
- You can decide to consult a vehicle technician.
- Do your personal vehicle code diagnosis and perform the required rectification as recommended.
It is not advisable to continue with the drive when the engine light gives continuous warning. This is because the engine in this condition is known not to function optimally and even though it may still be running shows a warning sign that all is not well.
Continuing with the journey is courting a calamity. So it is advisable that the vehicle be halted for the required rectifications to go on before the journey continues. Whatever you decide put the vehicle somewhere either under your own check or in the hands of qualified technicians.
When the engine light fault continues to pop up with no sign of it being erased, this is usually referred to as the intermittent check engine light syndrome. It is recommended for it to be rectified soon in spite of the fact that it is not that serious. Though it may be a minor fault, leaving it may cause a major condition which may not be as easy to rectify.
Some of the following are what the OBD2 scan tool can do;
- When triggered, it checks engine light and MIL lights
- Acceleration rates
- Engine idling, especially the rough mode.
- Fuel consumption rates above the normal.
Oxygen sensors P130-P167 or the EVAP codes P0445 are usually the likely causes of the check engine light situations. The worst part of this is that this may also cause an emission test failure and may turn the owner into a vagabond.
However, simple leak gasket alone may be the cause of some of the known OBD 2 faults. With the OBD codes, you are assured of an up to the minute help to both the owner and technician to rectify the problem.
To be able to effectively solve the problem, the technician or anyone requires precise fault detection mechanism. This may involve going as far as analyzing the data, the readers will be handy in helping g the mechanic and the client reach a mutually binding working relationship which is less costly and less labor sapping.
The monetary benefits to the technician in this case may not be overlooked because in some cases they may be forced to adjust their schedules and charges to meet the unrealistic fault time rectification schedules.
The good thing with the OBD2 machine is that it does not require a wide level of know how to be able to operate. Technicians whose knowledge is handy may be engaged but some people prefer working alone before any consultations.
In the later case, the technician’s are precluded from adding anything which may be of financial benefit to them. This is why with this tool, the technician must have a two pronged approach when charging for the service rendered.
OBD2 –the on board diagnostic system in perspective
Using what is usually only referred to as the system parameters. The on board diagnostic has been seen to effectively record engine trouble code within its memory systems especially when there is a fault. Despite not showing where the fault is, the codes enable the reader to see the area where fault its located which makes the fault identification quite easy. For the fault to be specifically identified, the breakdown and analysis are quite handy. Some of the bad sides of the on board diagnostic tools is giving incorrect information reading fuel.
To be able to scan effectively, the OBD2 scan tools are plugged into the engine. This alone initiates the coding and reading of data. Using some of the machines can be difficult however. This is because by giving you only the code and no meaning, you are lefty with the task of trying to k now what the meaning is.
It is therefore better if you went for the ones which give the code and definition though they are more advanced and costly. Automatic upgrades, freeze data, resetting of engines, display of data and the connection to the internet are what you get with the advanced models which are within your reach anyways.
For pundits, better performance is the key and achieving it is paramount whatever the case. That is why where exhaust emission is concerned, hidden engine software is usually tweaked by engine tuners to get street legal but better performing engines.
Cost effectiveness ids the code word in any investment on an OBD2 scan tool. Getting what is compatible and good quality is usually the aim of most novices. For knowledgeable and well informed technicians, using the advanced scan tools should be the main preserve.
With the rate of the competition brought by the electronic management systems, many technicians agree that the OBD2 reader is their best companion. The level of compatibility should be what informs your major decision when in the process of selecting an appropriate scan tool.
It it can work on several car brands, the cost is reduced, so check the vehicle compatibility because there are other older car versions not covered by the OBD2 emission requirement.
