Hey <a data-id="1203" data-value="Gus_Rubio10" data-denotation-char="@" href="/user/gus_rubio10" class="text-decoration-none mention">@Gus_Rubio10</a> , Great question! Thank you for asking it in our community. There are a few common reasons why a GO device may fail to read the VIN from a vehicle's computer. I used an AI tool to help compile this answer, so please let me know if anything needs clarification. The GO device reads the VIN by querying the engine ECU over the CAN bus. Whether this succeeds depends on how the vehicle manufacturer implemented that part of the ECU firmware. The most common reasons it fails are: - VIN not programmed in the engine ECU — especially after an ECM replacement, the VIN sometimes needs to be manually re-entered using manufacturer diagnostic software and is often skipped - The ECU returns a manufacturer-internal ID instead of the ISO VIN — some manufacturers store an internal build or calibration number in the VIN register rather than the standard 17-character VIN - ECU security lockout — newer ECU firmware versions on some makes require an authenticated diagnostic session before exposing the VIN. Without it, the ECU ignores the request entirely - CAN bus connection issue — if the device is operating in two-wire mode or is connected to the wrong CAN segment, it has no path to the engine ECU It is also possible a loose installation is causing this issue. its hard to say without looking the specific case but I hope this helps give you some things to look into. If the engine VIN cannot be read automatically, the most reliable workaround is to enter it manually in the device settings in MyGeotab. Please let us know if you have any follow-up questions - happy to help! Have a great day! Eishi FUN

¿Why do some GO9 devices not automatically decode the VIN?

The Location is updating correctly, but the Odometer hasnt been updated in 97 days. I have taken out the geotab, put it back in and it works, but the odometer is not updating.

Hi everyone, What is the exact meaning and operational threshold for the 'GNSS: Signal strength indicated by carrier-to-noise ratio (dBHz) of the strongest satellite signal detected' status record found under 'Engine Measurements' section? Additionally, what are the typical or optimal ranges (in dBHz) for this metric, and what do lower values mean regarding GPS tracking health, signal blockage, or potential interference? Thanks in advance!

Hello, 
I have a client who has asked me if we can adjust the volume of the G09, as her ID isn’t loud enough to encourage her drivers to clock in. 
Thank you

Good morning,I wanted to know if installing a GO9 device on a category N3 electric TRUCK vehicle (over 12 tons) provides battery status and all electrical information. Buongiorno,volevo sapere se installando un dispositivo GO9 su un veicolo TRUCK elettrico di categoria N3 (più di 12 tonnellate) è possibile ricevere informazioni sullo stato della batteria e tutte le informazioni relative alla parte elettrica.

GEOTAB GO blue light blinks every 5 seconds all night long.Is this normal? or is the GO wired incorrectly?The truck battery will be dead if not driven every day.

I have devices that don't give g-force measurements and are driving.

Why don&#x27;t I have G-force measurements from the GO device accelerometer? What kind of errors are related to this behavior?

Can we use the GO9&#x27;s native output wire to ground the bodybuilder speed limit input directly?

I have a Go7 device that is sending very strange coordinates; in this case, it's sending its position in China.     069Pd00000xLhpeIAC.png


Why does a GO device send incorrect coordinates?

Set up as single asset, vehicle shows in the asset log but not on the map, it's as if the GPS isn't working

I have a Go with the following FW version that has not been updated.Does this version still work, or do I need to update to a Beta version?

Is there a way to check the battery status of a vehicle with the GO device?
