One of the questions asked by
some workshops dedicated to the maintenance of vehicles in the electronic part
is that of What scanner should I buy?
There Are Several Questions That As A Workshop I Should Ask Myself:
- I am a workshop that attends different brands or do I distinguish myself by attending only one or two?
- What level of attention am I going to pay to the vehicles? Do I only work on electronic engine control? Or do I generally attend to the different electronically controlled systems?
- The models of vehicles that I work in the workshop are very varied, some are vehicles are known as the first generation (OBD I) and I also serve vehicles of newer models of the second generation OBD II?
- In the workshop do I need to program modules, code keys?
In response to some of these questions, factories that develop
automotive diagnostic equipment offers the market different ranges of automotive a scanner such as:
- There are Automotive Scanners focused on allowing the shop to perform specific functions such as resetting the oil lights (after vehicle repair and maintenance, the maintenance team can be used to disable or reset the warning lights on the dash to eliminate unnecessarily warning), program tire pressure sensors (after changing tire pressure sensor or changing tires, which can make the ECU re-identify signal transmission data and the position of each tire sensor ), to reset the steering angle (calibrate the data zero point and actual steering wheel position stored in the ECU after a four-wheel alignment is complete).
- There are also a wide variety of automotive scanners of different brands on the market focused on reading fault codes from the OBD II system, as a rule vehicles manufactured in the United States from 1996 and in Europe from the year 2000 must comply with the standards of the OBD II system (Within them all vehicles must have a sixteen (16) pin connector according to the SAE J1962 standard), in our Latin American countries we have different types of vehicle models that have this connector but they do not necessarily comply with all the regulations of this system.
- These scanners allow the technician to obtain the different fault codes that are stored in the ECU but only those related to the electronic engine control, additionally they allow the technician to erase the fault codes and only works on vehicles that have DLC of 16 pins, models prior to this system cannot be verified with this type of diagnostic tools.
- We also find other types of intermediate scanners that allow the technician to enter the models that have a 16-pin diagnostic connector, but not only enters the engine but can also enter the other electronically controlled systems such as (Automatic gearboxes, ABS brakes, airbags or SRS supplemental restraint systems, etc.), allows the technician to verify fault codes, clear fault codes, and read current parameters on each system.
Like the previous type, it can
only scan vehicles that have a 16-pin diagnostic connector, and it is not
possible to work with previous models of this system.
- Also in the market different brands of automotive scanners are offered that are called as high-range or coverage, these are the original Equipment or Scanner of each brand or the so-called Automotive OEM Scanner. This type of diagnostic tool is considered a high level, because its coverage in brands is quite complete and in terms of the different types of functions they allow the technician to work in all the vehicle systems that generally vary from brand to brand. Even among the different models, the type of specialty in these tools comes close in an important percentage to all the functions that can be carried out with an equipment considered original.
With this type of scanner the
technician manages to enter the reading of fault codes or DTC, erasing the
fault codes stored in the control module of the system that presents the fault,
you can read the different current parameters that the vehicle has in real-time
in the system that is being read, allows to carry out special functions that
may vary according to the brand or model that is being worked on, such as
motorized throttle calibration, coding of diesel injectors, cylinder balance,
checking the power provided by each one of them, checking the operation of the
injectors in a gasoline or diesel engine (it allows the scanner to cancel the
operation of an injector either randomly or manually), in some models it allows
coding the keys, They can be activated (the fans, the operation of the fuel pump
and the activation of different accessories such as electric windows, alarm,
windshield wipers, radio, etc.
These devices are mostly sold with software that can be updated online for a period of time, some brands allow it for a period of one year, others for two years, but the most important thing is that at a cost you can continue updating so that the tool does not become obsolete.
