900 S Sedan V6-2498cc 2.5L DOHC (1995)
The signal from the climate system to turn on the A/C compressor passes via the ICE, see also Electronic Climate Control Systems.
9. Electrically Heated Rear Seat
The ICE controls the length of time the electrically heated rear seat remains switched ON.
When the switch is pressed, the ICE switches on the heating pads for 5 minutes. It then switches them OFF for 2.5 minutes and ON again for
another 2.5 minutes before it switches them OFF altogether.
After this it will be necessary to press the switch to turn ON the heating pads, following which the entire cycle will be repeated.
It is possible to activate the heating pads during the 2.5 minute turn-OFF period by pressing the switch. The complete cycle will then start
from the beginning again.
Current is disconnected for a maximum of 20 seconds during starting.
