From the wording in the service manual, any fault disables ABS. So if you unplug a wheel speed sensor, it will disable ABS. I think the speedometer on the dash uses the rear right sensor, so unplugging any one of the other three should do it with no adverse penalties (other than the ABS light on the dash).This may have been covered before, but what's the easiest way to disconnect the ABS on my 2006 Elise?
I too have had the joy of ICE mode, would like to avoid those hair rising moments.?
