Car Vehicle Tracking – OBD 2 + ELM 327

It is possible to read the error codes, turn off the light of the injection and make a diagnosis of defects of your car just by using your phone and an OBD2 connector called ELM 327. OBD2 stands for “On Board Diagnostic System” or is the main way used today to discover defects in vehicles.

Car Vehicle Tracking - OBD 2 + ELM 327

Just do the car tracking and the electronic central of the vehicle will report several possible problems with sensors and electronic components. In addition, other operating problems can be inferred from the sensor readings on the vehicle.

In this article we talk about the OBD Car Doctor app that allows you to communicate with the electronic central of the car using Blueetooth and an OBD 2 connector like the ELM 327.

The OBD Car Doctor can be downloaded for Android from the app store and is only 1 of the many apps available to perform this task. It is very complete and has a paid version and a free version, which was used in the video that illustrates this article.

The ELM 327 connector can be purchased for $ 5 from these Chinese sites like Deal Extreme and Ali Express. I preferred to buy one that cost $ 12 as I saw that I had good recommendations from other customers who bought them previously. The cheaper OBD2 connectors had no reviews on these sites or there were many complaints about the quality of the product. Choose one that fits your needs. In general, compatibility with car models needs to be taken into account when defining the app to be used, since OBD II connections are standardized on newer vehicles. I will not go into detail because I do not have a complete list with all variations of interfaces, connections and protocols. In any case, since the objective is only to facilitate the obtaining of information about the vehicle,

The OBD Car Doctor in its free version already has many interesting features as you can see in the video that illustrates this text. It is possible to read various sensors and information from your car and, in the paid version, show several of them at the same time on the screen, which is something I would have liked to have done in the video in question, but I only found out later.

How to connect the ELM 327 in OBD Car Doctor Bluetooth

The hardest part of doing all this work was to sync the Bluetooth with the ELM 327. Follow the steps below to make the ELM 327 work

  • install OBD Car Doctor on your mobile phone
  • connect the ELM 327 to your car’s OBD2 port. (each car has this door in a different location)
  • turn the key to turn the panel on (I did this because I’m not sure if it’s mandatory)
  • turn on the bluetooth of your mobile
  • pair with the OBDII device that will appear in the device list. The PIN is 0000 or 1234
  • open the OBD Car Doctor to authorize the use of Bluetooth
  • the program will connect to the ELM 327 and begin testing each protocol
  • Please wait, this will take several minutes. (it took 12 minutes for me to work)
  • when you connect, you will see the sensor options and information ready to be chosen (see video)

After the connection has been made, you can turn the car on and even get out driving around and see how the information on each sensor varies. The OBD Car Doctor even displays several interesting graphs with the information that the electronic control system of your car has. For those who like technology and cars, it’s a lot of fun.

Obviously the interpretation of the video information for vehicle repair and maintenance purposes should be made to a qualified automotive maintenance professional: a reliable mechanic. In any case it is very good to have access to the data informed by the car to facilitate the conversation with the mechanic and help in the diagnosis by informing the “symptoms” of the problems. Do not make interventions or mechanical changes in your car without proper knowledge because you can put your life and that of others at risk. Go to a workshop and take the information you get, do not use it as a base for maintenance if you are not sure what you are doing.
