Engine faults related to telematics devices

Initial Checks: Visit the Measurements page in MyGeotab.Diagnostic Procedures: Check if the device is still reporting engine data.When to seek professional help: If the device stopped reporting engine data around the time of the fault.

Initial Checks: Visit the Measurements page in MyGeotab.Diagnostic Procedures: Check if the device is recording accurate accelerometer data. Take note if the vehicle has been driving off road more often than usual.Potential Solution/Fixes: Verify device installation. A loose install may result in erroneous collision events.When to seek professional help: If it has been verified that the device install is secure and is not in an environment prone to excessive vibration, or if the issue began following a firmware update.

Initial Checks: Did the device lose power unexpectedly?Diagnostic Procedures: Confirm if the device was power cycled at this time. The fault will be recorded when the device powers back up.Potential Solution/Fixes: Check for unexpected power resets. These could be caused by a loose install, power supply issue, kill switch, or unplug of the device.When to seek professional help: If the device is reporting excessive reset faults and common causes of power issues have been ruled out as the cause.

Initial Checks: Was the device recently unplugged?Diagnostic Procedures: Confirm if the device was power cycled at this time. The fault will be recorded when the device lost power but won't be sent to MyGeotab until the device reconnects.Potential Solution/Fixes: Check for unexpected power resets. These could be caused by a loose install, power supply issue, kill switch, or unplug of the device.When to seek professional help: If the device is reporting excessive unplugged faults and common causes of power issues have been ruled out as the cause.

Initial Checks: Was the device recently installed for the first time?Diagnostic Procedures: Check the timestamp of when the fault was recorded.

Device will brownout at approximately ~7-8 V.Possible causes:Device master switch is resetCertain Feature Flags (FF) enabledRemote scan tool resets the device

Initial Checks: Did the device lose power unexpectedly?Diagnostic Procedures: Confirm if the device was power cycled at this time. The fault will be recorded when the device powers back up.Potential Solution/Fixes: Check for unexpected power resets. These could be caused by a loose install, power supply issue, kill switch, or unplug of the device.When to seek professional help: If the device is reporting excessive reset faults and common causes of power issues have been ruled out as the cause.

Initial Checks: Check trips history for straight lines on the map or breadcrumb trail not displaying as expected.Diagnostic Procedures: Did the device recover on its own? If the problem persists, follow the standard device troubleshooting process for GPS issues.When to seek professional help: Device is not tracking trips correctly and standard GPS troubleshooting has been completed. In this case, contact Support as the device may require replacement.

Initial Checks: Was the device recently installed for the first time?Diagnostic Procedures: Check the timestamp of when the fault was recorded. If the device was still provisioning during this time then the fault may be expected (if on x.0.57 or x.0.60 firmware).Potential Solution/Fixes: Ensure the device finishes provisioning.When to seek professional help: If this fault is recorded after a device has finished provisioning, contact Support

Initial Checks: Confirm whether or not the vehicle was in a collision, or if the device recently had its installation modified.Potential Solution/Fixes: If an erroneous collision event was detected, verify the device installation.When to seek professional help: If the vehicle was not in a collision and the installation of the device is confirmed to be secure.

The following are required to calibrate:Harsh driving eventValid GPSStable acceleration in the Z axis (~9.81 m/s^2)

Initial Checks: Accelerometer calibration requires some trips to complete. Ensure the vehicle has been driven.Diagnostic Procedures: Valid GPS and stable orientation is required. Verify the device is installed securely and has a clear view of the sky. Accelerometer calibration will occur after each power cycle.When to seek professional help: If the device has not calibrated accelerometer over multiple trips.

Initial Checks: A network fault code (U-code) was detected by the device. Check the faults page in MyGeotab to see if a vehicle fault was reported.Diagnostic Procedures: Isolate the cause of the network code. Does the fault go away when the GO device is unplugged? Try swapping out the GO device or harness (if applicable). If the issue persists contact a mechanic or technician for further diagnosis.When to seek professional help: If the issue goes away when the GO device is unplugged, contact Support.

Fault specific to GO7/8 devices only, does not apply to GO9 or newer.Logged when 6-pin harness is detected, but engine data is not received for 5 minutes after ignition.

Default IMU Channel exceeded its separate accident-level log limit and is fully disabled.Logging of accident-level accelerometer events will remain disabled until the next device reset.The Default Channel tracks the log count of accident-level events separately from nominal-level events to help ensure that accident-level events are not lost due to the log limit being reached.Note: this behavior is separate and distinct from the Collision IMU Channel.
