Porsche 996 TT, Repair Manual

Page: 98 / 2099

The PCM reverts to the Code input
function when the battery is
disconnected and is thus no longer
ready for operation.
•
When the power supply is
disconnected, the built−in GPS
receiver loses the so−called almanac
containing the satellite orbital paths. •
The date and time are deleted when
the battery is disconnected. •
Radio stations stored by the customer
are no longer displayed.
•
If the telephone card was inserted
and the telephone was ready for
operation, the telephone is
subsequently disabled. •
Input the PCM code. If the code card is unavailable,
the PCM code can also be read from the DME
control module (under "Vehicle data").
2. This code is also available from the Porsche IPAS.
3. Switch on the PCM with a free panoramic
view for approx. 20 minutes (to load GPS
almanac).
4. The date and time are also adopted once the GPS
almanac has been loaded; it may be necessary to
change over to summer time (daylight−saving time).
This time is transferred to the instrument cluster. If the
time is then manually changed by means of the
instrument cluster, this time is adopted by the PCM and
synchronised with GPS time.
5. The stored stations are displayed again when
station buttons 1 to 6 are pressed.
6. The telephone is enabled again when the
telephone PIN code is entered with the SIM
telephone card inserted.
