Instead, please contact FTS Support. We can help with scheduling a technician visit to your vehicle through our nationwide installer network.

Step 1

• Verify that the vehicle is in area with good coverage.
• Is the Vehicle in a building with a metal roof or sides?
• Is the Vehicle in underground parking or a parking garage?
• Is the device installed in an area in the vehicle that is surrounded or concealed by metal?
• Is the Vehicle in a remote location where signal can be interrupted?

If the vehicle is in an area with good coverage, please continue to step 2.

Step 2

Verify the Suntech ST4500 device is getting power:

• Is the vehicle powered on?
• Is the device connected correctly?
• Is the diagnostic port (OBD-II/JBUS/RP-1226) on the vehicle providing power?
• Have any fuses in the vehicle blown?

Step 3

Verify what combination of LED lights are on, and in what state (e.g., flashing or stable).
Icons are shown in the diagram below.

Note: The LEDs lights shine through the casing of the ST4500. There are no visible LED windows when the device is OFF.
