If the question is answered with
"YES", the control unit will be reprogrammed with the programmming
code shown in the display. Note that when the control unit is reprogrammed,
it presumes that it is installed in a vehicle with manual transmission. For
vehicles with automatic transmission, therefore, shift at least once from
"P" or "N" to "D" and back again with ignition
ON after programming. The control unit is then aware that it is
installed in a vehicle with automatic transmission.

If the question is answered with
"NO", the sub - menu on the right appears in TECH 1.

By selecting menu item F1:
CHANGE, it is possible to reprogram the control unit to any desired code. At
present, however, only the code for the basic application is permitted.
Further codes and their applications will be published in the relevant
"Technical Information Bulletins TI". This procedure will be used
in the future for any performance improvements that are required (previously
various coloured RON coding plugs). In addition, note the control unit
presumes that it is installed in a vehicle with manual transmission after
reprogramming.

If the display on the right
appears after programming, an invalid programming code has been entered.
Programming should be repeated
with a valid code.
