Testing & Troubleshooting the Suntech ST4500 Series Devices

In order to test the device, the vehicle must be parked outside in an open area so that it can receive a GPS lock. The device’s LEDs will indicate proper operation.

If you do not observe LED’s, please check the owner’s manual to determine which fuse provides power to the OBD-II port and verify that it isn’t bad.

An experienced technician can run a volt meter to the OBD-II port to verify that it is receiving 12 volts of power.  Find a ground source for the negative test connection and tap the positive end of the test connection to port 16 of the OBDII port.
