Establish the connection to the heater! The heater status does not affect this in any way. Check the appropriate
cables and plugs.
The diagnostic adapter starts already to work at a voltage of 9V. Once the supplied voltage is at least 9V and the
cable to the diagnostic adapter is not damaged, the status LED "24V" should work. Please consider that a heating
device with a rated voltage of 24V usually operates correctly at a voltage of more than 18V.
Check the vehicle system voltage (20V - 30V)! It may be that the LED "24V" works, but nevertheless a data link
cannot be established (e.g. because the heater voltage is no more than 12V).
Check the cable and the plugs. Replace them if necessary. Use another USB port at the PC. Verify the USB inter-
face using a device of which you know definitely that it works correctly.
To establish a data link, it is required that the "24V" and "PC" LEDs light up. If this is not the case, proceed as
described above.
Have you installed the PC software? Restart the application! You may have opened the program several times.
Close all Spheros programs. Open the program "Spheros Thermo Test" only once!
Eventually, the control device is defective. This can be determined by exchanging it.
Make sure the heater and the diagnostic adapter use the same ground potential.
Have you installed the driver for exactly this diagnostic adapter? For each diagnostic adapter its own driver must
be installed. Launch the diagnose using the menu or press "F2" key.
Causes:
a) The installation was carried out without full administrator rights. Remedy: Uninstall and reinstall application.
b) The relevant USB port of the computer is locked.
c) The USB adapter is not connected to the computer.
