Features of BlueDriver

Read and Clear Trouble Codes – When your car’s engine has a problem, a vehicle’s computer tries to tell you by turning on Check Engine Light on the dash. At the same time, the computer stores Trouble Codes for you to identify the problem. OBD2 scan tools can get access to the computer and retrieve the codes.

You may see the codes even when Check Engine Light is off. Depending on codes, the computer takes a certain time to trigger Check Engine Light and stores trouble codes (Permanent codes) after it detects a problem. During this time, the computer stores these codes as Pending codes. BlueDirver can read and clear both Permanent and Pending codes.

Read and Clear Enhanced Codes (ABS, Airbag, and Transmission for supported makes and models only) – While most OBD2 adapters can get access only to vehicles’ engine computer, BlueDriver can do it to ABS, Airbag, Transmission modules. This feature is limited to supported makes and models. Currently, they are GM, Ford, Chrysler, Toyota, BMW, Nissan, and Honda. A company continuously works on developing to make more makes and models supported.

Repair Reports – Once you get a trouble code, you will get a report containing details of the code, possible causes, and reported fixes. The app matches your car’s year, make, and model then provides a report from a database of over 6.6 million fixes verified by certified automotive technicians. Although you may get this information by searching on the internet, it takes time to reach a specific. You might end up reading unrelated articles or guess works and advice from armatures. Repair Reports save your time. They are organized and ready to provide you the correct information, and more importantly, they are keeping updated.

Freeze Frame – It’s a snapshot of PIDs such as RPM, coolant temp, mass airflow volume, etc at the moment a trouble code is stored. With Freeze Frame data and Repair Reports, you will know where to start diagnosing to identify the cause of the problem.

Smog Check – Also known as I/M readiness monitor. It’s a set of self-test done by a vehicle’s computer, showing Ready or Not Ready. It tells you whether your car is ready to be taken to the state inspection. Regulation of inspection varies from the state to the state. So, it may pass the inspection even if one of the tests is Not Ready

Mode 6 – It’s an advanced test result. Unlike Smog Check, Mode 6 shows test results in values. When values exceed a maximum or minimum threshold, a vehicle’s computer illuminates Check Engine Light. In other words, no matter how close the value is to the threshold, the computer doesn’t set trouble codes even if you feel something wrong with the vehicle. Mode 6 is used to find a problem with a vehicle without Check Engine Light. Depending on the vehicle, Mode 6 may show either raw hex values or interpreted test IDs and values.

Live Data – It shows real-time engine data such as RPM, coolant temp, speed, etc. A list of data varies from vehicle to vehicle. In general, the newer cars, the more numbers of data provided. You can customize Live Data Dashboard by selecting PIDs, changing the color, displaying in a graph, gauge, or digital style. You can also create a file to export and log.
