5. If the telephone card was inserted and the tele-
phone was ready for operation, the telephone is
subsequently disabled.
90 80 On-board computer:
Disconnection of the vehicle battery deletes the
memories for average speed and average con-
sumption.
As a result, the displayed range on remaining
fuel can be markedly different or even O.
The outside temperature indicator loses its me-
mory effect. In other words, the indicated out-
side temperature can be too high due to the heat
radiated when the vehicle is hot.
Remedy:
1. Input the PCM code. If the code card is una-
vailable, the PCM code can also be read from
the DME control module (under 'Vehicle data").
This code is also available from the Porsche
IPAS.
2. Switch on the PCM with a free panoramic view
for approx. 20 minutes (to load GPS almanac),
91 20 Radio:
3. The date and time are also adopted once the
GPS almanac has been loaded (see step 2); it
may be necessary to change over to summer
time (daylight-saving time). This time is trans-
ferred to the instrument cluster. If the time is
then manually changed by means of the instru-
ment cluster, this time is adopted by the PCM
and synchronised with GPS time.
The radio reverts to the Code function when the
battery is disconnected and is thus no longer
ready for operation.
Remedy:
Input the radio code. If the code card is una-
vailable, the radio code can be read from the DME
control module (under 'Vehicle data"). The code is
also available from the Porsche IPAS.
4. The stored stations are displayed again when
station buttons 1 to 6 are pressed.
9110 PCM:
5. The telephone is enabled again when the tele-
phone PIN code is entered with the SIM tele-
phone card inserted.
1. The PCM reverts to the Code input function
when the battery is disconnected and is thus
no longer ready for operation.
2. When the power supply is disconnected, the
built-in GPS receiver loses the so-called "alma-
nac" containing the satellite orbital paths.
3. The date and time are deleted when the bat-
tery is disconnected.
4. Radio stations stored by the customer are no
longer displayed.
