If for example the display shows 2, this means that the swivelseat-switch is controlled, or that the
wiring to this switch is defect.
In combination with the detail drawing of the wiring (attachment

86900 CW eng)

it should be easy to

solve the problem, if the problem is related to the wiring.

An 8888x error is shown as a 4x blinking eight and then failure code .
All 8888x errors will generate a fast beep (5Hz).
Exception for error 8888J (error 13) This one does not generate the fast beep.
