9. Locating and correcting malfunctions.
For problems in functionality we have made a document called “functionality and troubleshoot type
87”.
That document gives a detail explanation of all logic and has all schematics as attachment.
In this chapter global info is given.
9.1 Diagnostic display
A display on the PCB shows the actual error. More detail info of this display errors is attached to this
document. (attachment

.
The display can show the following errors.

If for example the display shows 2, this means that the swivelseat-switch is controlled, or that the
wiring to this switch is defect.
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 13 = > 8888J)
