CONNECT NAV+
The CONNECT Nav+ system is
able to detect both internal faults and
faults due to overheating.
INTERNAL
FAULTS
If the system detects an internal fault
on a certain module (audio, telephone,
etc…), the system will “freeze” the
last available screen and it will start di-
agnostics.
For a set period of time the system
monitors the involved module for
troubleshooting. If time-out expires
with no result, the system will adopt
the best repair action (e.g.: resetting
involved module hardware).
Should the system be not operating,
reset it manually by pressing the
knob17-fig. 1 for over 7 seconds.
OVERTEMPERATURE
FAULTS
If the temperature of a CONNECT
Nav+ hardware module (audio, tele-
phone, CD player, etc..) exceeds the
max. limit, the module will detect
overtemperature and the display will
show a dedicated warning message.
The involved module will automati-
cally be limited or disabled. In extreme
cases the system is turned off auto-
matically until regular operating tem-
perature is restored. The display will
show the screen in fig. 173.
