The Data Adapter
© BlueFire LLC ↑ Go to the top Version 3.3 | Page 5
The Adapter only receives data that the ECMs transmit. If the ECMs are not programmed to
transmit the data then the App cannot show it and will return a value of NA. Some sensors of the
vehicle may also be mechanical or hydraulic and not connected to an ECM in which case the App
will show NA.
To check what data the ECMs are transmitting, use the Drive and Repair pages of the App. If the
values show NA then the ECMs are not transmitting the data.
Connecting the Adapter
Before connecting your Adapter you should first explore the App and become familiar with its
functions (see the sections 'Exploring the App' and 'App Settings' below).
Step 1
Plug the Adapter into the data port of your vehicle.
The Adapter is keyed such that you have to rotate it until the male key aligns with the female key
in your diagnostic connector. You'll feel it drop in. The Adapter also has a locking ring that has to
mate with the diagnostic connector so you may have to rotate this until you can push the Adapter
all the way in. Once the Adapter is all the way in, you can lock it by twisting the locking ring until it
clicks.
The Adapter sends the data from the vehicle's onboard computers via a wireless Bluetooth
connection. Bluetooth has a range of 20 to 30 feet. It cannot transmit though metal so don't use
the data port on the engine at the rear of your vehicle.
Step 2
Check the Adapter's LEDs.
The Adapter will be blinking blue indicating that it is ready for you to connect the App.
The Adapter has three LED colors, Red, Green and Blue. In general, Red is for the Adapter, Green
is for the vehicle connection, and Blue is for the Bluetooth connection. The LEDs can either be
solid on or they can blink. The red LED can also pulsate. Below is a description of their meanings:
Solid Red - The Adapter is updating its memory. DO NOT unplug the adapter otherwise
undesirable results may occur.
Blinking Blue - The Adapter is ready and waiting for you to connect the BlueFire App.
Blinking Green - The Adapter is ready and connected to the BlueFire App but is waiting for
you to turn the key on.
Solid Blue - The Adapter is connected to the BlueFire App and communicating with the on-
board computers in your vehicle.
