911 Carrera (996) Tiptronic diagnosis
Notes on on-board diagnostic
An on-boarddiagnostic system with fault
memory is integrated in the Tiptronic control
module. It can detect and store certain faults
on the electronic transmission control system
(see fault overviewon Page 37 -0 17).
If a fault is present, it is first stored
as a static fault. If the fault no longer exists,
it first becomes a sporadic fault and "Fault
not present" appears on the display
of the tester. The counter is set to 40
in this case.
Sporadic faults are deleted automatically
after 40 cold starts of the engine (followed
by transmission warm-up),
