How to Set Up Your FIXD Sensor

To successfully set up your FIXD sensor and FIXD app account, please check the following items:

         1. Make sure your vehicle is compatible

              – Vehicles that are 1996 and newer AND sold in the US are compatible

               – Vehicles that are 2006 and newer that are sold elsewhere are compatible

                – Diesel vehicles are compatible from 2008 and after

         2. Make sure you have a compatible device.

                  – iPhones and iPads with operating system 14 and beyond are compatible

                  – Android devices with operating system 4.4 and beyond are compatible

           3. Make sure you have a strong cellular connection.

                   – Most of the app functionality requires 3 bars of data connection

                   – Some wifi signals are not strong enough outdoors so disconnecting may be necessary

Once you have checked these items, you are ready to get connected! Just watch the video below and follow the steps!

Step 1:

Download the free FIXD app for iOS and Android on your phone.

Step 2:

Turn Bluetooth on. NOTE: Do not pair with the sensor in the bluetooth settings. Pairing with the sensor will happen automatically within the FIXD app. Simply turn on your bluetooth through your phone’s settings.

Step 3:

Register an account in the FIXD app.

Step 4:

Select your repair preference and make sure you enable the maintenance reminders!

Step 5:

Select “I have a FIXD sensor”

Step 6:

Input the sensor code found on the back of the sensor (ex: CV11111)

Step 7:

Turn on your vehicle.

Step 8:

While the engine is running, plug your FIXD sensor into the OBD2 port underneath your dash (usually underneath the steering wheel on the driver’s side). You may need to get out of your vehicle to be able to see it. The image below shows the most common locations to find your OBD2 port.

Check to see if a blue light flashes on your sensor when you plug it in. The blue light means that the device has power and you will see it flash repeatedly during the scanning process, so if you do not see it, let us know!

Step 9:

The app will scan for a nearby sensor. When the sensor is detected in your app, tap “I found it” and enter your vehicle name and VIN.

Your VIN is a 17-digit number that can usually be found on the lower-left corner of your dashboard right in front of the steering wheel, at the front of your engine, inside the driver-side door jamb, or in the rear wheel well.

How to Complete Your First Car Scan with FIXD

It’s that simple! After the FIXD Sensor scans your vehicle for diagnostic fault codes, you’ll be able to see the simple description of your code, know how severe it is, view potential fixes, track maintenance and wear items, and more for free inside the FIXD app. (Cost estimates and confirmed fixes are only available for FIXD Premium members.)


Can I Diagnose Car Problems with FIXD without a Check Engine Light? :

Yes! If you’re having an issue with your vehicle that isn’t detected by the FIXD Sensor, you can use the app’s manual diagnostics feature to describe the problem.

First, perform a scan of your vehicle. If no error codes are detected, you’ll see this screen:

Next, click on “Still having an issue with your car?” and you’ll be taken to the FIXD Diagnostic Flowchart where you can describe how your problem looks or sounds and get detailed information regarding possible causes.

Connecting Your FIXD Premium Account

If you have purchased FIXD Premium or are taking it for a test drive as a trial user, you must connect your Premium account with your FIXD app in order to unlock the Premium features.

If you download the FIXD app and aren’t able to access your Premium features, don’t start a trial in the app! Look for an email with the subject line “Thank you for joining FIXD Premium! *Action Required*” and open it to connect your Premium account with your FIXD app.

You’ll know you’ve successfully connected your Premium account to the app when you click on the Premium tab and are able to access the features. If you have any questions, don’t hesitate to reach us at

Connecting Multiple Vehicles to Your FIXD App

Many of our customers ask: “Can I connect multiple vehicles to my FIXD account?” The answer is yes, FIXD was designed with multi-car families in mind. 

One FIXD Sensor can be used with multiple vehicles, but we do recommend having one device per vehicle in order to get the most out of it. 

You can plug in multiple sensors to each vehicle your family owns and connect them all to one account on your phone. This makes it easy to monitor vehicle health from anywhere. With the multi-vehicle control feature, you’ll also receive notifications when other vehicles in your family are experiencing problems or are due for important service like oil changes.

How to Add Multiple Vehicles to FIXD

In order to add multiple vehicles, you’ll need to access your “Garage”, which is the 3 cars located at the top left corner of the app.

There you will see the option to add another vehicle, indicated by the “+” sign in the top right corner, or the “Create Vehicle” button at the bottom of the side panel.

You will then be asked for the vehicle’s information and the sensor that you will be using. After submitting this information, your second vehicle should be good to go!
