ICS blown fuse, now won't let code input
The ICS on a car I sold recently(2000 166 2.5 V6 24V) has just blown it's fuse. The fuse was replaced and didn't blow again.
BUT the system will not let the code be re-input.
The screen with code input comes up OK but the cursor stays on number 4 and turning the right hand rubber knob does not have any effect, therefore the correct code cannot be entered.
I have tried disconnecting the battery to reset the system but no joy there.
Anyone else had a problem similar? Is there another way to reset the ICS?
Or is it broken!
