he Trackunit Fit mobile app helps installers verify that a Trackunit device is installed correctly before leaving the installation job.
It confirms that the device is:
Powered correctly
Wired correctly
Reporting asset data (including CAN, when available)
By completing this verification, you ensure the device is ready to deliver reliable data from day one.
After verification, device health can be monitored in Trackunit Manager.
Note: There are two different Trackunit Fit apps. This article is about the Trackunit Fit app (blue icon) for self-install.
Trackunit Fit (Field) app is for Trackunit-contracted technicians.

Before you start
Before starting an installation verification, make sure:
Your mobile device has network connectivity
Bluetooth® is enabled and your camera is working
The asset and device are accessible
You have a Trackunit Manager account with access to the device
Download and sign in to the Trackunit Fit app
Start by downloading the Trackunit Fit mobile app to your smartphone using the links below:
Open the Trackunit Fit mobile app
Tap Sign in
Enter your Trackunit Manager credentials
If needed, use Forgot password to reset your login.
If you do not have a Trackunit Manager login, ask your organization’s admin to create an account for you. Learn how to manage users
Start a new installation verification:
From the home screen:
Tap Start installation
Identify the device by:
Scanning the barcode, or
Entering the serial number (S/N) manually
Tap Start Service
Describe and configure your asset
You’ll now complete the asset setup. This ensures correct configuration and enables validation.
1. Asset Metadata
Enter details about the asset.
Fields may be pre-filled if the asset already exists
Fill in as many fields as possible
Use:
Camera icon to scan text
Template icon for predefined values
This step ensures the asset is correctly registered and helps determine CAN compatibility.
2. Asset Details
Enter basic asset information:
Select power type
Choose:
Off-road (uses hour meter), or
On-road (uses odometer)
Enter:
Engine hours, or
Odometer reading
3. Select the CAN Profile
Select a CAN profile for the asset:
If unsure, choose the top option
If CAN is not used:
Tap Skip CAN Installation Setup and Select a reason
Once configured, continue to device validation.
Review device details
On Install Home, review Device details to confirm the device is connected and reporting data.
Key metrics:
External power supply
Device battery level
Mobile signal strength
Bluetooth® connection
You’ll also see:
Last Communicated – last time the app received data
Last Device Data – last time the device reported status
These fields show a red warning indicator to alert you if data has not been received for an extended time.
Example: In the screenshot below, the Trackunit Fit app is online and receiving real time updates, but the TU700 Raw last reported status 13 minutes ago. At the time it reported the device battery was charging but Bluetooth® was not connected and 4G signal was poor.
For the installation verification to be completed, this device needs to be moved to an area with cell connectivity or have its Bluetooth® connection enabled to resume live status updates.
Once the device is reporting data, continue to the next step below.
Adjust device settings
Tap on Device details box to see a more detailed view of your device
From here, tap on Device Settings
Input filtering (if applicable):
If the main breaker is installed on the negative wire, the device inputs may register a current and start counting operating hours.
To avoid this:
Connect digital input 4 (pink wire) to chassis/ground
Enable Input Filtering
Note: When Input Filtering is enabled and input 4 is active, inputs 1–3 are disabled.
All digital input alerts are disabled, including alerts on input 4.
This applies to Raw devices (TU600/TU70) running firmware 63.08 or higher
If Input filtering is enabled, it appears as Pending until updated.
Input configuration
1. Tap on Input config.
2. Set trigger values for each input
We recommend at least 0.5V difference between high and low voltages. This will help reduce false positives.
High [V]: Trigger value when the voltage increases (9.5V by default).
Between 0V and High [V], the input status will be OFF
Between High [V] and 58V, the input status will be ON
Low [V]: Trigger value when the voltage decreases (7V by default)
Between 58V and Low[V] the input status will be ON
Between Low[V] and 0V the input status will be OFF
3. Optional: Use the Invert toggle to reverse logic
Note: When Invert is toggled on, it will cause the reading to flip the high/low voltages. For example, if a device is set to high at 9.5V and low at 7V, it will show as inactive when the input is 10V or above.
4. Optional: Additional inputs
Use Input 5 to detect if the light sensor has been exposed to light
Use Input 6 to detect active relay.
5. Tap Save at the top of the screen
Run certification checks
From Install Home, tap Certification.
Certification checks run automatically and confirm your installation meets requirements.
Each check passes when:
Metadata – Required fields are complete
Power – Device receives sufficient external power
Input Wiring – Wiring is validated
CAN Bus Validation – CAN data is received (if applicable)
You can bypass a check if needed.
When bypassing a check, you must provide a reason (either written or selected from a list).
Bypassed checks are marked with a yellow indicator
They remain part of the certification record
Complete input wiring validation
From Certification, tap Start Now under Input Wiring Validation to begin the validation flow.
You will be guided through five steps based on the asset type. These steps ensure that the device receives power, measures usage correctly and collects advanced data (if applicable).
Input Wiring Validation steps:
💡 Carefully read the instructions at the top of the screen for each step.
Machine off: Confirms the device has power and is not counting usage
Do: Turn machine off completely. Switch off isolators, shut-offs, and kill switches.
Ignition on: Verifies correct ignition behavior for the asset
Do: Turn on the battery isolator and ignition switch. Do not start the engine.
Running: Ensures operating hours are recorded correctly during use
Do: Start the engine Let it run for 30 seconds. Watch for any fault codes on the app display.
CAN validation: Confirms CAN Bus connection and data transmission
Do: Check CAN activity. If there's no signal, check the wiring or restart the asset.
If the wrong CAN profile is selected, you can change it here.
If CAN is not used, add a Bypass Note
Shutdown: Ensures the device stays powered and stops counting usage after shutdown
Do: Turn engines off. Switch the key to OFF to complete the test.
Once completed, return to Install Home.
