Scan
tools have become absolutely necessary in modern automation. Professional
mechanics and garage technician are indebted to the auto scan tool that will
probably let him know immediately what is wrong with the engine. So what is a
scan tool? It is a device that is used to obtain and access diagnostic
information on board an automobile. They come in various shapes and sizes but
there are usually two main types: the stand alone and the computer based. The
former does not require a computer to work, has a small screen with a modest
interface and runs only with the help of some software with limited functions.
The cost too is small compared to the PC based scan tool, which has a number of
advantages, e.g. large and easy to read screen, unlimited storage space for
data, a good selection of software that can be updated, ability to located data
remotely etc.
These
scan tools are generally standardized and can be used in a majority of
automobiles. This standard is called OBDII or On board diagnostics, version II.
This keeps a check on the emission levels of the automobile. Generally, the
fuel injection, ignition system and automatic transmission on most modern multi
fuel injected automobiles and vans are run with the help of one or more
computers. These computers monitor sensors and collect data of all parts of the
engine and other systems in the car. These then send commands to the fuel
injectors and ignition coils to fire cylinders to begin the running of the
car’s engine. This same data is also used to fine-tune the process of
combustion with the right amount of gasoline and give the car the correct
ignition timing for the provision of efficient, clean combustion for optimum
power and low pollution. Actually, there are a number of sensors that measure
each function of the car engine e.g. throttle opening, air and coolant
temperature, engine rpm etc. The Scan Tool system has the capability to self
correct the fuel mixture and ignition at every crankshaft revolution. If there
is a major problem with any one of them which the scan tool cannot self
correct, the mechanic will know at a glance what it is and rectify immediately.
It is also a great tool to scan air bag and ABS codes and can diagnose and
clear all related problems. This situation is definitely better than what it
was a few decades ago.
For
motorcycle enthusiasts, bonding with their bike is pleasure. They will know the
running of their bikes only if they tinker with all its minutest parts. As
motorcycles are specialized high performance machines they use specific
hardware and proper motorcycle tools to be maintained effectively. These tools
consist of carb fuel and chain tools, drain pans, engine and hand tools, racks
and work mats, spark plug and suspension tools, safety wire etc. Most of these
motorcycle tools can be folded way for easy storage.
