E 0504.10

Does anyone know what this code is? E 0504.10?
The unit starts and goes through its cycle, then this code appears.
The unit works and operates normal, but has no horn.
The unit can be operated all day, but its a safety issue, because it cuts out the horn.
The horn and the diode in-between the horn terminal is good. All fuses are good. Battery voltage is 49 volts.
Customer does not want to use the machine because of the horn not working. Safety issue.
Anyone with this issue, or can explain the problem?
