Device not reporting or updating

possible causes: tampering, wiring problem, sim card failure, device failure

Sometimes a device will stop reporting or updating, either intermittently, or permanently. First thing you'll have to do is find out how long ago and then look at the history to see if there is any indication that a fuse has blown or something else.

Towing

When a device reports Possible Towing, it's reporting this because it is sensing motion or movement, it has calculated it has moved from the last place the ignition was turned off. If you are seeing a lot of towing, it can be caused by a few factors relating to a less than ideal installation.

Power disconnect

When a device reports Power Disconnect, it is because of incoming power (red wire = constant voltage) (black wire = ground) has stopped. Eg. red wire disconnected. Troubleshoot by checking the device and wiring harness using a multi-meter or vehicle diagnostic probe to ensure all wiring is connected correctly and securely.

Vehicle route is not smooth

Moving: no ignition detected

When a device reports Moving, No Ignition Detected, it is because of ignition sense wire (green wire = ignition) is not detecting power level voltage. Troubleshoot by checking the devices green wire using a multi-meter or vehicle diagnostic probe to ensure power level voltage. You can check the below links for vehicle wiring diagrams.

GPS Police products have two LEDs for diagnostics:

A green led for the Unit and GPS status
A red led for the cellular modem's status

Green LED

^{Compatible with: Ping, Link}

^{The green LED (unit/GPS status) has the following blink patterns:}

On duration	Off duration	Status
10ms	20 seconds	GPS has turned off or no main power
100ms	4 seconds	GPS is turned on, with a valid position
100ms	400ms	GPS is turned on, no position
Always on	-	GPS is turned on, no communication with GPS

Red LED

^{Compatible with: Ping, Link}

^{The red led (cellular modem status) has the following blink patterns:}

On duration	Off duration	Status
-	Always off	Unit has no power, modem is off, SIM card not inserted
100ms	10 seconds	Unit is in low power consumption mode, modem still on
100ms	4 seconds	Unit is connected to network
100ms	1 second	Unit is connecting to network
Always on	-	Modem is connected to server
