SpartanLync Tools (MyGeotab App Integration) - Frequently Asked Questions (F.A.Q)

What is the SpartanLync "ECU Device ID" Number?

The SpartanLync "ECU Device ID" Number is a 6-digit combination of letters and numbers printed on the outside cover of every SpartanLync ECU device, which is physically connected to a Geotab GO device within a vehicle.

Why is the "ECU Device ID" Number Important?

The ECU Device ID is communicated to Geotab every time the Vehicle Ignition occurs. Therefore seeing this ID in SpartanLync Tools indicates a working SpartanLync / Geotab Installation and connection.

This ECU Device ID will appear in the SpartanLync Tools App AFTER;

1. Ensuring the SpartanLync ECU device and the Geotab GO device are physical connected
2. Turning on the vehicle ignition and hearing a beep from the SpartanLync ECU device, indicating a successful power connection
3. Waiting up to a max of 5 minutes
4. Launching SpartanLync Tools App or refreshing the Vehicle list by clicking the Vehicle "Refresh" button.

Look for this ID within the SpartanLync Tools App, beside a Geotab Vehicle name "e.g. 2022 (0012AB)" in the Vehicle List (where 2022 would be the Geotab Vehicle Name and 0012AB is the SpartanLync ECU Device ID).

If you do not see a SpartanLync ECU Device ID beside the Geotab Vehicle name, that means that according to the Geotab network, an SpartanLync ECU has not yet been plugged into a Geotab GO device AND TURNED ON via vehicle ignition WITHIN a defined time range (default 24 hours) shown in the SpartanLync Tools App Settings "Device ID Search Range"

To resolve, follow the steps explained above OR change the "Device ID Search Range" setting to 48 or 96 hours, and then click the vehicle "Refresh" button to search within the last 2 to 4 days respectively for a Vehicle ignition occurrence with correctly installed hardware.

Additionally, an asterisk symbol (*) beside the ECU Device ID in the Vehicle List indicates SpartanLync Tools at some time in the past found ECU Device ID "00209F" for vehicle "Lab Rat 4 - GORUGGED" and remembered it, BUT DID NOT find that ECU Device ID on the last Vehicle Refresh within the defined "Device ID Search Range", e.g. the last 24 hours from starting the SpartanLync Tools App.

This makes the asterisk symbol (*) a very helpful diagnostic tool to identify whether the ECU is communicating correctly right now with its paired GO device on that vehicle.

Why is the "ECU Device ID" Number found ONLY after 48 hours WHILE Sensor data was found for today?

This is very common behavior that will be seen often, especially in a 3-wire harness installation, like a 24/7 Reefer solution.

The Geotab GO telematics device will report:

• Sensor Data every 2/3 minutes when the vehicle is STATIONARY (or less when vehicle is MOVING) and the data has changed.
• ECU Device ID on IGNITION of vehicle.

Therefore you can expect to get much more frequent sensor readings reported than transmissions of the ECU Device ID, especially in a 3-wire harness situation where the YELLOW ignition wire is not disconnected very often; leaving you to have to search longer in SpartanLync Tools for a ECU Device ID reported.

In a vehicle, this means that;

1. The vehicle is stationary with a long or infinite standby power and the ignition off (configurable as custom parameter or the MyGeotab setting shown below)
2. or a vehicle has been moving or idling non-stop without being turned off for over 24 hours.

You would have to research further about the installation in that situation to find out which of the above scenarios is true.

In Sensor Reports, Why is the timestamp for TempTrac Zone 1 sensor different than the timestamp for Zone 2 sensor?

This is very common occurrence as Zone 1 and Zone 2 sensors are completely independent.
