ICE (Integrated Central Electronics)
|
ICE (Integrated Central Electronics) is a programmable
electronic unit which controls a number of relays as well as sending
and receiving information to and from different components.
Signals controlling the following lighting system functions go out
from
ICE:
|
•
|
Interior lighting and reading lamps
|
|
•
|
Direction indicators, hazard flashers
|
|
•
|
Monitoring of rear parking lights and brake lights
The following lighting system components send information
to
ICE:
|
|
•
|
Stalk switch for lights
|
|
•
|
Direction indicator switch
|
|
•
|
Switch for extra fog lights
|
|
•
|
Brake-light switch
The following information is sent
out
from ICE:
|
|
•
|
Rear or brake light bulb failure to the auxiliary instrument panel
|
|
•
|
The sound to be used for the direction indicators
|
If a bulb at the rear fails, ICE sends a signal to the
auxiliary instrument panel which grounds the "BULB FAILURE" warning
lamp in main instrument panel 1.
If a bulb at the front fails, the filament monitor grounds the lamp in
the main instrument panel via the auxiliary instrument panel.
If the car is equipped with auxiliary instrument panel 2 or 3, ICE and
the filament monitor send a signal to the auxiliary instrument panel,
which lights up a message on the display:
|
•
|
REAR LAMP FAILED
|
Simultaneously, the auxiliary instrument panel lights up the INFO
DISPL lamp in main instrument panel 2.
ICE also controls a "Follow me home" function, i.e. if the headlamp
flasher is activated after the door has been opened, dipped beams will
remain on for about half a minute.
For more information on ICE and fault diagnosis in the lighting system,
refer to Service Manual 3:5 "Electrical system, instruments"
