This function will display the errors that are detected by the controller in the attachment parts.
Enter service code 1C. The character display will display "1C t oP" first. Then, the character display will display the error codes. The following procedure is used in order to view the error codes that are present. The error codes are displayed in the right four character positions. The display will show "End"on the character display, if no problems are present.
The fine control mode switch (25) is pressed in order to flash "1C t oP" on and off.
When the boom priority mode switch (23) is depressed, the character display displays the
