Troubleshooting

The Green and Red LEDs are intended to aid in troubleshooting installations. Below is a summary of their behavior.

Green LED

Red LED

The red LED flashes two-digit codes. The first digit indicates which general area is having a problem (hardware, modem, GPS, end-end service). The second digit gives specific error information. Since there can be more than one error condition, the device rotates through the error codes (e.g. if the GPS is tracking no satellites and the modem is not registered).

1-1: The device has an expired license key due to a failure to resync with the VTS configuration server. Contact VTS with the serial number of the
1-2: Low supply This could be caused by a true low voltage condition (<8V) or a high impedance supply that dips in voltage when the current draw spikes due to modem transmit.
1-3: Allocated data usage exhausted. Contact IntelliShift Technical Support for further instructions.

2-1: Modem module fault. Contact VTS for failure analysis and
2-2: No SIM Make sure the SIM drawer contains a SIM and that it is correctly seated in the socket. If it is, then contact VTS for failure analysis and repair.
2-3: No Check that the cellular antenna is correctly attached. Try to substitute a known-good cellular antenna to see if the antenna may be broken. If this fixes the problem, then reinstall a new antenna. If not, then RMA the unit to VTS for failure analysis and repair.
2-4: Network not found. Contact IntelliShift Technical Support
2-5: Last data session This means that any attempt to establish a data session failed. This failure will occasionally happen in a working unit, but if the problem is persistent Contact VTS.
2-6: Network is not available.

3-1: GPS module fault: Contact VTS for failure.
3-2: GPS antenna fault: try replacing the GPS antenna with a known good antenna. If the condition is not corrected after 2 minutes, contact VTS for failure.
3-3: GPS not tracking any satellites. Check that the GPS antenna has a clear, unobstructed view of the sky and has been operating for at least five minutes. Check that the GPS antenna is facing the correct way up. If the condition persists contact VTS for failure analysis.
3-4: GPS no fix (less than three satellites). If the antenna only has a partial view of the sky due to the position of the vehicle (e.g. under a cover, close proximity to a building, etc.) then try to move the vehicle to ensure that it will be able to make fixes when standing in the open. If the vehicle has a full view of the sky and the error condition persists then try to reposition the GPS antenna to reduce any obstructions from its view of the sky.
3-5: GPS has no GPS receiver that sets its internal clock from the satellite signals. If the GPS receiver has no time, then it has never seen a single satellite since the device was last power cycled.

4-X Error Codes: End-to-End Application Error Codes

4-2: Data transfer failed. If the condition persists then contact IntelliShift Technical Support.
