Hello <a data-id="7817" data-value="asauc-7817" data-denotation-char="@" href="/user/asauc-7817" class="text-decoration-none mention">@asauc-7817</a> , Thank you for asking your question in our community. I did see some of these error codes coming up not too long ago but they are all that common s thats probably why the documentation is limited on it. Fault code 155 is associated with an invalid opcode reset. This means the GO device reset after its firmware encountered an invalid instruction. Because it happened only once and the device is still working normally, this does not by itself indicate a hardware failure or require an RMA. The device appears to have recovered successfully. I recommend monitoring it for now. If the fault repeats, the device stops communicating, or other symptoms appear, please contact your reseller or Geotab Support for further investigation. Please let us know if you have any other questions. Hope that helps! Eishi FUN

FAULT 155 in MyGeotab

To figure out when a device was offline, you can check the following logs in MyGeotab: 1. Log and collision data: Go to Activity &gt; Log and collision data. 2. Radio access technology: Look for the 'Radio access technology' diagnostic. Changes in these logs or long periods without GPS&#x2F;engine updates while the vehicle is in use indicate disconnections. 3. Engine faults: Look for faults like 'Backfill pending' or 'Telematics device fault,' which can be recorded when the device loses communication.

How can I see a history of when a GO device goes offline?

I am not sure how many codes you are adding perhaps using a rule with the or criteria between each code. Then it would report exceptions that you can build a report or add notifications for alert.

What vehicle is it coming from if it is a HD truck it could be Transmission Electronic Module tied to an AUX switch in the vehicle.

What is fault code 520572 in MyGeotab

Hey Everybody, I am trying to identify some issues with how MyGeotab identifies power loss in a Surfsight camera for use with Exceptions. For example, I have a camera that has been offline for over a month.  I can see a Camera fault: all power removed - device restarted (1. Fault occurred) fault for the day that it went out, but exactly 1 second after the measurement was triggered it goes back to 0. So, I'm beginning to think that this fault is only catching when it happens, but not remaining on for the duration of the time the camera is out. Does anyone know if this is expected behavior? I also have 18 instances of the Road-facing camera status (0. DECALIBRATED, 1. CALIBRATION_IN_PROGRESS, 2. CALIBRATION_COMPLETE, 3. ADJUSTMENT_SUGGESTED, 4. ADJUSTMENT_REQUIRED) fault set to 0 (DECALIBRATED) for the same day the camera went out (which occur both before and after that power-removed fault). So, I guess I'm wondering if anyone knows how to find a measurement that indicates if a Surfsight camera has gone out and, if so, if that measurement will remain in the "yes-this-camera-has-gone-out" state until the camera comes back online. Thanks in advance for any help you guys can provide!  :) Best,Joy B

Identifying Surfsight Camera Power Loss

We have a Caddy connected to GO9 and it seems it is sometimes losing GPS and when looking at fault codes i can see these three messages: Telematics device fault: Collision data is unavailable for 10 minutes due to excessive logging of Collision events. If this fault occurs three consecutive times then the GO device disables logging any suspected Collisions until the device is reset. During the night the GPS signal was off for two hours between 03:00 - 05:00 and these are the faults that came later. Could there be a connection to gps? 

Fault message that may relate to bad GPS

Wha does fault code "Alert: Collision limit for acceleration exceeded" mean?

I am receiving these asset fault codes today for one of our assets.  I cannot seem to locate any info on what this is.  Please advise, thank you.

How do you resolve a 287 FAULT CODE in MyGeotab

Do Unauthorized Removal of the device mean the driver unplugged the Geotab device or could it mean the device went offline?

Who can I get an alert everytime this happens? Does this mean the employee removed the device? I am trying to understand this.
