Inspection tools are straightforward to use and depend entirely on the user's knowledge and investigative skills however, it is fairly simple to distinguish a broken part from a functional one. For example, a broken bearing will sound particularly rattly or create grinding noises that would not be apparent without the use of a hearing aid. The stethoscope allows the user to listen to the harmonics being produced which is used to find issues and help figure out the problem-causing part. Similarly, a mechanic’s stethoscope is a device that enhances any sounds or disturbances to diagnose failure issues with many engine components like bearings, water pumps, injectors, etc. which would not show up on any electronic scan tools but can only be determined using good ol’ fashioned prying. This allows the mechanic to determine problems like carbon buildup on cylinder walls and valves, broken crankshaft bearing, damaged piston walls, etc. Inspection cameras provide an insight into areas and sections of the engine which would not be possible without complete dismantling of parts. They can be especially useful if the faults lie in areas where you cannot easily see or perhaps in an enclosed section like the cylinder combustion chamber inside the engine. When it comes to diagnostic tools, one of the most useful devices is an inspection camera. Instead, they make it easy to solve the issues by helping you isolate the faulty system in the engine and various other components. It is useful to note that these tools are not magical devices capable of solving all vehicle-related problems.
#MOST EXPENSIVE CAR DIAGNOSTIC MACHINES PROFESSIONAL#
Professional OBD scan tools are generally only used by dealerships and manufacturers as they are more advanced and have features like ECU reprogramming, emission control, etc that are not directly relevant to the average DIYer.Ĭode readers and scan tools have become increasingly popular as they are a relevant and easy source of finding and fixing common problems associated with most vehicles and using one are very simple. This information can be helpful as it allows the user to solve the issue more efficiently. Scan tools are more advanced and along with reading and displaying the engine codes, this device is also able to give solutions and reasons for the issue to occur. The codes alone can not be enough to find a fix and you may have to further investigate the codes by looking them up online.
The cheapest of the bunch is simply able to read the OBD system and spew out all engine codes related to the fault.
#MOST EXPENSIVE CAR DIAGNOSTIC MACHINES CODE#
There are several types of code readers and scan tools available on the market today with varying prices and capabilities.
Every system in the car has a different trouble code and this allows the technician to pinpoint the specific area of the problem using the related engine code. A code reader or scan tool reads and displays the related engine trouble code. This information is then used to access trouble codes from the engine, transmission, exhaust, and various other systems in the car. Since the inception of the OBD II system in 1996, every new vehicle has had a standard onboard diagnostic system that stores information in the vehicle’s electronic control module.
