A Critical Review of Auto Diagnostic Tools by a Mechanic

A Critical Review of Auto Diagnostic Tools by a Mechanic

What is an auto diagnostic tool?

Over the decades, there have been technological advances in several areas of automotive industry. The most beneficial development for mechanics and consumers was the computerization of car components.

With the help of utility software, auto diagnostics tools can accurately and speedily pinpoint to areas of trouble. The auto diagnostics tools are now enabled with diagnostics capabilities through built-in microchips, sensors and processors.

On-board diagnostics (OBD) is now a common terminology in automotive industry for auto diagnostics tool.

OBD as an auto diagnostic tool provides necessary access to the mechanics and vehicle owners for the vehicle subsystems.

The auto diagnostics tools can clearly indicate the issues relating to the following areas of the vehicle:

  • Build-up level in engine
  • Problem relating to ignition timing
  • Fuel injector’s performance
  • RPM levels of the engine
  • Ignition coils and its firing
  • Coolant and air temperature
  • Position of camshaft
  • Position of crankshaft
  • Throttle opening issue

The auto diagnostic tools rely on the systems of computerized process that connect with the system microchips, processor and sensors of the vehicle. It sources the issues and logs the problems.

With these inputs, the auto diagnostics tools provide flaws relating to the problem of transmission, oil tanks, exhaust, and other systems.

The auto diagnostic tools provide accurate assessment of the car. Mechanics can scan computerized system of the vehicle for gathering diagnostic trouble codes. Then they can check service notifications as provided by the vehicle manufacturers.

To confirm, mechanics can perform physical test via visual inspection or on-road tests. With such analysis with auto diagnostics tool, mechanics can get into further examination for comprehensive battery checking and systems charge analysis.

On the other hand, some other tests can also be performed for identifying other troubles of the car. This is how auto diagnostics tools help in pointing out the issues reliably and speedily, relating to the vehicles.

Such indicators or alerts can be made available without inspection of the vehicle physically.

It also provides idea as how the vehicle can be put back on road safely.

Benefits of auto diagnostic tools

Earlier car diagnostic was expensive and time-consuming. It was only performed at the car service station after any breakdown or getting some signals on malfunction of the car.

With the introduction of large-scale computerized system in automotive industry, auto diagnostic tools are now able to detect the issues relating to car malfunction.

The biggest benefit of the auto diagnostics tool is to get early alerts before any major damage is done in the car by ignoring the problem in the system.

The other benefits of diagnostic tools are:

  • Checking computer system of the vehicle for manufacturer notifications
  • Retrieving information of the vehicle stored in the system
  • Analyzing vehicle history
  • Providing technicians a complete picture about malfunction and parameters
  • Guiding mechanics about the repair required.

The key benefit of auto diagnostics tools is in use as a preventive system. One can avoid taking car to a mechanics when the engine light is turned on all of a sudden.

In case, vehicle owner use auto diagnostics tool before hand for a regular check and analysis, it will prevent such critical condition in most of the cases.

It is because when light is on and blinks incessantly, there is a clear possibility that the car is headed to a serious breakdown. There may be a case that it is too late.

However, if auto diagnostic tool is used as preventive mechanism, one can easily understand performance and issues relating to performance of the car in advance.

It also provides signals about the potential issues which may cause performance problem in coming days.

With the further analysis by using the auto diagnostic tools, one can go deep into the vehicle system and dig out further analytics to gain closer insight on the car performance issues.

In this manner, auto diagnostic tool is used by the users and his or her mechanics to analyze performance issue of the car. The advance diagnostic helps in gaining peace of mind for the vehicle owner.

Knowing that there is no issue with the car or any potential trouble, one can safely go for long distant drive with peace and safety. It provides immense help in getting confidence that the car will not behave unusually in between journey or in a lonely road.

What are the areas of test?

There is nothing worse than to start a day with engine light on or blinking in the car. To avoid such situation, one can do a regular test with the help of automobile diagnostic tools.

As observed before that the tests can be performed to avoid any unusual trouble in car. There are various tests possible with today’s sophisticated auto diagnostic tools. The test can be done with the help of engine scanner or engine code reader.

It suggests whether one should go ahead with drive or suspend it. It can also provide enough signals to fix the problem upfront.

The same can be done by plugging the scanner / reader into computer system of the vehicle where system indicates the trouble code.

The engine scanner / code reader is efficient auto diagnostic tool which is worth buying for an amateur mechanic.

Though car diagnostic tool does not provide complete solution but it clearly provides the head start on the trouble area. But before doing any replacement and repair, one needs to do some more investigation.

This can be done by analyzing various other indicators and sections of the car. For getting better knowledge about auto diagnostics tools and its usage, one can subscribe to online manual.

It helps in getting additional information which can facilitate in interpreting the indication provided by the engine code reader or scanner.

From the online manual, one can check carmaker’s technical bulletins relating to service as listed with complete diagnostic procedure for a code.

The same also provides walk through about the testing procedures including the guidance on which wire to check or what voltage is to be looked at.

The test and service process can also suggest the part locators which can help in finding the part in the car including wiring diagram.

This is how automobile diagnostic tools provide greater support in car maintenance.

 Who can use auto diagnostics tools?

The diagnostic tools can be used by the vehicle owner himself. On the other hand, in today’s world of computerized car servicing, mechanics regularly use the auto diagnostics tools for car system analysis and investigation.

To use the auto diagnostic tools by vehicle owner, one needs to ensure that he or she has right diagnostics tools.

It is also necessary in the process, to know as how to read diagnostics codes relating to trouble via alphanumeric indicators.

This is created by society of Automotive Engineers (SAE). It is worth to learn for greater car performance and using auto diagnostic tools effectively.

Auto diagnostics tool…value for money

The diagnostic process is not a break down maintenance. It is much more worth if it is used as preventive and regular check-up process.

One should not consider using auto diagnostics tools after engine light is on or it starts blinking incessantly.

The idea is to use auto diagnostic tool at periodic interval to perform regular check-up and also note the changes in car’s performance.

At the minimum, one must perform test by using auto diagnostics tool or get it done by the authorized mechanic, once a year.
