Hi all. New on here. Have a customer having an issue where nothing will work on their machine. However by the time I get there it is going fine. They have given me the error code 001-093. I found that combination weird as I know 001 is a battery voltage issue not sure why it also has 093. Does anyone know more about these as I normally work on crown, Toyota, BT and only have two of these I look after.

I have tested the battery. It's ok.

Also the error will last anywhere from one minute to half an hour before coming good and then may go over a month before happening again or may happen the next day.

Any help would be appreciated.

Michael.
