When a transmission disturbance occurs, the “Transmission
Fault” warning indicator lights up in the multi-function display
and display 5 of the operating panel flashes simultaneously.
The disturbance is stored as an error code in the error
memory. There are five storage locations available for error
codes, which are labelled “d1” to “d5”.
When the diagnostics mode is opened, the error code of the
first storage location “d1” is always shown first in display 5.
Using MODE KEY 3, you can open the error codes of “d2”
to “d5”.
The error code consists of a letter and a four digit number,
e.g. P0722.
Example of an error code display: d1, P, 07, 22.
This means that the error code P0722 is stored in d1.
If there is no error, the displays shows the following:
d1, - - -.
The list of error codes can be found in the
documentation of the transmission manufacturer.
