Jeep are unique cars, they have not only high cross-country ability, but also have excellent build quality and highly reliable units. If you own just such a car model, then you are confident that you can overcome any obstacle, Jeep is one of the best cars. But even such reliable and high-quality cars often do not stand our harsh conditions, especially the engine suffers. However, modern diagnostic methods allow to establish the fault in the shortest possible time. If you need to urgently improve the performance of your engine, return it to its former power, conduct its computer diagnostics. Exactly today we will talk about the best diagnostic devices for Jeep, which will allow you to quickly determine the cause of failure, if your car has such problems as:
- The “check engine” light has come on.
- There is a persistent smell of gasoline (oil) in the cabin.
- Your vehicle “shakes.
- You hear extraneous or abnormal noises from knocking to grinding.
- There is white or black smoke coming from the muffler.
- Car does not start well.
Advantages of Computer Diagnostics
The main positive aspects of carrying out just such a procedure can include: high speed of detecting the cause of failure, there is no need to perform a complete disassembly of systems and units, high accuracy of diagnostic measures, the possibility of conducting a comprehensive diagnostic. As a result, it leads to serious saving of time and money. Nowadays, computer diagnostics of the following systems and elements is performed: engine, fuel system, automatic transmission, brake system, suspension system, steering, electrical equipment, security system.
Types of Automobile Scanners
Devices for reading information may be in the form of a stand-alone device with its own software and hardware, or a special complex for a PC. The complex includes not only the software for the OS, but also a set of adapters.
There are 2 types of car scanners:
- multimaroc;
- Dealer.
Multimode scanners are characterized by the ability to work with multiple vehicles. Their advantage is the installation of several protocols for data exchange with the ECU. Such devices come with a set of cables and adapters. It allows you to work with different configuration of diagnostic connectors. Unfortunately, most multimaster scanners have limited functionality. As for the dealer-type scanners, they are designed to work with one or more car models. They support a specific protocol, which means that they can work only with “related” brands. Among the features of dealer car scanners are: a set of all kinds of functions and slave diagnostics. It allows you to analyze ECU data and uses a special algorithm to identify possible causes of errors and determine how to eliminate them.
How Is the Computer Diagnostics Performed?
Since 2004, all cars have been equipped with an OBD-II connector. A scanner is connected to it, which detects errors, reads key parameters and allows some settings to be edited. There is also a connector in some earlier cars. In the U.S. it has been installed since 1996. Since 1989, the less popular OBD-I computer diagnostic system has been used, which is now very rare.
The procedure begins with checking the electrical part with a multimeter. You need to make sure that all connectors are intact, the battery is charged, there is sufficient voltage in the mains and there is no current leakage. If there is an electrical malfunction, the car’s computer diagnostics can give false results. Next, the owner of the car is interviewed. A minimum of information is required from him – how the car behaves, what are the complaints, what is unusual lately.

Bottom Line
The essence of most repairs is clear without technical skills – a damaged part is replaced, a scratched body is polished, a crumpled wheel is rolled. The computer diagnostics of the car is more complicated – the driver is told the result, without going into the nuances of the process. And today we told you about the diagnostic devices, their types and best options. We hope you found this article useful!
