CODE 303

Does anyone know what code 303 is? I have a stock picker Model-SP3020-30, SN-1A254870 that will periodically throw this code and then the code will clear itself, and truck runs fine. can anyone help?
Thanks

This status code is displayed when the logic +12 volt output is out of tolerance. This voltage is used internal and external to the display module. A driver isolates the external from the internal, so an external short circuit should have no effect on the internal voltage.

Possible Cause

Faulty display module

That what the code says
