D5M service codes

Hello all,

I am after some help with a D5M XL,the dash warning for battery, transmission and sometimes fuel, lights up and the warning buzzer goes off after start up.
The unit still moves in all directions ,steers and functions as normal.

I toggled into the service code section on dash between RPM and Hours and have written a sequence of codes that appear in order.

030
271F05
113
298F02
113
368F02
113
621F02
END

I am hoping that someone out there has knowledge of where...
