I am writing for current, future and former motorists. After all, the former will become current anyway :) So here he is the hero of our review: ELM327 OBDII Bluetooth.
Bluetooth was chosen because in the past there was an experience of owning a usb scanner. It is inconvenient that you have to constantly drag a laptop and a wire behind it again. Wifi did not want to. a little haemorrhaging settings connecting it. And with a blue-tooth there were no problems with pin 1234 (of course there are a lot of very complex variations such as 0000, 6789, 2345, 5678. depending on how it is determined), but the bulk accepts exactly 1234.
The ELM327 Bluetooth adapter is modern andA convenient tool for diagnosing a car using a personal computer. All OBD-II protocols and a huge number of specialized diagnostic programs are supported. Unlike the USB version, it allows you to carry out diagnostics at a distance, in addition, you can use it not only with a personal computer, but also with a PDA and mobile phone (you need the appropriate software). The list of supported cars includes almost all cars with an injection engine produced after 1996.
Supported OBD-II Protocols:
• ISO15765-4 (CAN bus): Audi, Opel, VW, Ford, Jaguar, Renault, Peugeot, Chrysler, Porsche, Volvo, Saab, Mazda, Mitsubishi
• ISO14230-4 (KWP2000): Daewoo, Hyundai, KIA
• ISO9141-2: Honda, Infinity, Lexus, Nissan, Toyota, Audi, BMW, Mercedes, Porsche
• J1850 VPW: Buick, Cadillac, Chevrolet, Chrysler, Dodge, GM, Isuzu
• J1850 PWM: Ford, Lincoln, Mazda
Data Rate: 9600 or 38400 kbps
LED Indicators: OBD Tx / Rx, RS232 Tx / Rx, Power
Operating voltage: 12V, built-in overload and short circuit protection circuit
Power Consumption: 45 mA
Using the ELM327 Bluetooth adapter, you can perform the following operations:
• Read diagnostic error codes, both standard and special manufacturer codes, as well as display their meaning (the database contains more than 3000 codes for various errors)
• Clear errors and turn off the MIL (the inscription "Check Engine" on the dashboard).
• Display values of various sensors, including:
- Engine speed
- engine load
- Coolant temperature
- Fuel system condition
- Vehicle speed
- Short-term fuel consumption
- Long-term fuel consumption
- Absolute air pressure
- Ignition timing
- Intake air temperature
- Mass air flow
Decryption of error codes OBD2. Pin Designation OBD2
Reading OBD-II codes:
P - is for powertrain codes - the code is related to the operation of the engine and / or automatic transmission
B - is for body codes - the code is associated with the work of "body systems" (airbags, central locking, power windows)
C - is for chassis codes - the code refers to the chassis system (chassis)
U - is for network codes - the code refers to the system of interaction between electronic units (for example, to the CAN bus)
0 - common code for OBD-II
1 and 2 - manufacturer code
3 - reserve
Third position - type of fault:
1 - fuel system or air supply
2 - fuel system or air supply
3 - ignition system
4 - auxiliary control
5 - idling
6 - ECU or its circuits
7 - transmission
8 - transmission
Fourth and fifth position - error serial number
Searched not for long. The main thing for me was an adequate store manager who quickly and competently answers questions. That is why I began to look at sellers with a small rating. They need to grow and mean attitude to the buyer should be good. And by the way, I was not deceived in my expectations. They answered quickly and on business. Paid on 04.10.2014. On October 12, the first mention of him appeared on the mail site, and on October 31 he came to me. Total almost 22 days in transit or 30 days from the date of payment. Which I think is very, very good.
came in the usual standard postal yellow packet. In which the scanner and the disk to it were in the antistatic bag.
The Russian post probably had a break in domestic football matches and therefore even the envelope was not wrinkled :)
And so we unpack, take pictures. There will be no dismemberment. I honestly tried to open it to look at the workmanship, but it is well sealed and I was afraid to break it. I still have to work with him. Dimensions D48hSh25hV30 Nothing backlash and does not stagger.
Disk with software standard 250 mb Diagnostic programs for almost all operating systems and even with “treatment”
because I will use it from the phone, I installed the program Torque Pro downloaded from w3bsit3-dns.com. to the forum 4pda.ru/forum/index.php?showtopic=193433
there is also an older version on the disk, but I didn’t even try to install it.
I don’t even know if this program should be described herebecause on different machines she will see different sensors. My Lagoon 3 was afraid that he won’t see anything, because Renault everything is imprisoned for its scanner renault can clip, but the price tag for it starts from 200 bucks for a normal clone (I think I'll strangle my amphibian somehow and buy it). There are extensions to this program for cars. This is all beautifully painted on the w3bsit3-dns.com forum. For owners of Logans, Sanderos and Duster everything is perfectly readable, by engine. For in-depth diagnostics is not suitable, but look at engine errors, and even the little things.

Here are the settings for those who bought the ELM 327 wi-fi version
In the settings, open wi-fi and select the 327wifi network, then go to the settings of this network and prescribe the following:
IP address: 192.168.0.15 (last digits from 11 to 254, usually 11, 38, 123, experiment)
Subnet Mask: 255.255.255.0
Well, actually, probably all.
The device has some pluses. There are no cons. And what can be the disadvantages for such money. You can certainly find cheaper, but as they say avaricious pays twice.
