Blindsight can appear offline for a number of reasons, the most common reasons are:
Blindsight does not have 4G and cannot connect to the cloud
Blindsight has been uninstalled, or the machine is not in use
Power issues
Troubleshooting step 1
Confirm that the device has power. There should be 12-24v being received when the machine's ignition is turned on. If the status lights are on, this is a good indication that there is power.
Troubleshooting step 2
Check all connections are tight and in the right place, and there is no damage to cables - visually inspect power cabling, the BPU harness, and vehicle wiring.
Troubleshooting step 3
Check fuses.
Troubleshooting step 4
Confirm that there is 12-24v being received through the Blindsight harness to confirm there isn't an issue with the harness itself.
Troubleshooting step 5
Confirm that Blindsight has a 4G connection. You will see a slow flashing green light if there is no data connection.
-Check antenna for damage and that the connections are tight.
-Ensure sim card is active.
-Try and hotspot a connection and contact Presien support.
