If you need to check other systems, you need to purchase a commercial program.

Characteristics

Feedback about ELM327 suggests that the adapteris able to read faults, display their codes and description. EML327 is a microcontroller that was created to reduce the cost of manufacturing a scanner. Some manufacturers produce processors that have a copy of the adapter software. This does not adversely affect the reliability and quality of the connection. The diagnostic tool includes the adapter with the processor, OBD-2 cable and USB, a disk with free software. The technical characteristics of the adapter include:

• presence of LEDs;
• high speed of data exchange;
• internal protection against voltage drops and short circuits;
• operating voltage 12 V;
• OBD-2 connector with sixteen contacts;
• USB cable.

Should I buy OBD2 ELM327? Testimonials are advised to try this instrument for diagnosis, since the scanner communicates with virtually all brands of cars and supports the specification of OBD-2, regardless of the protocol and features of the vehicle.

Capabilities

What are the advantages of ELM327 Bluetooth? Feedback from car owners confirms: it's easy to use a wireless adapter. He not only reads, deciphers errors, but also erases them. Reading parameters takes place in real time. The engine speed, its load, coolant temperature, speed, fuel system status, short-term and long-term fuel consumption, fuel pressure, ignition timing, acceleration time and other parameters are diagnosed, depending on the vehicle model. All information is provided in the form of graphs. Sometimes it happens that the adapter can not do auto diagnostics if it does not have an OBD2 connector.

Which adapter to choose

How to choose the right adapter ELM327 Bluetooth? Reviews of owners are advised to buy the device, depending on which device will be used for diagnostic testing. It can be a smartphone, tablet, laptop, computer. For any PC, any adapter is suitable. For a smartphone with the operating system "Android" or "Symbian" adapters with Bluetooth and WiFi are suitable. For gadgets running under iOS, only the ELM327 WiFi adapters are selected. The manufacturer offers to buyers devices of three versions: Classic stick out from a socket not seven centimeters, Mini - on three and a half, Micro - on two centimeters. When choosing an adapter, use the following guidelines:

• if the diagnostic connector in the car is located under the steering column and is not heavily recessed, give preference to the modification of the ELM327 Micro or Mini adapter;
• if the connector is located on the dashboard and covered with a special plug, it is best to choose a micro adapter;
• if the diagnostic connector is in a convenient place from the point of view of ergonomics, the adapter of any modification will do.

After diagnostics, the device should be removed from the connector.

Instructions

What can the ELM327 adapter do? Reviews of car owners say that the device can read and decode fault codes, remove errors from the memory of the vehicle control unit, read the parameters of the ICE in real time. There are certain requirements for the personal computer during the diagnosis. Among them, the amount of RAM is not less than 16 MB, a free hard disk space of 50 MB, a USB port, high speed connection, an Intel Pentium processor. To connect the device simply, just install the program on the laptop and configure the adapter.

Reviews

Feedback on ELM327 is mostly positive. The users of the diagnostic adapter confirm that this is an inexpensive, user-friendly device. Its main advantages are accuracy, a variety of indicators, error reset. The adapter reads parameter values ​​from the engine ECU, it does not require drivers and wires for connection. The device is small in size, compact, suitable for almost all car models, multifunctional, simple, can be saved on diagnostics, used as an on-board computer, does not require unnecessary settings. From the shortcomings: it does not work with all programs and systems, build quality is not the best, in some car models the adapter is difficult to remove from the connector.
