Question: If the fuse of the ABS on a 1998 V70 is pulled, would the
speedometer continue to work?
Thanks.

Well, I know that the speedometer gets it's speed signal from the front
ABS sensors. If that info is relayed by the ABS computer, then that's
why the speedo won't work.

Isn't the feed paralleled off before the ABS computer?
Cheers, Peter.

I'm not sure if the feed is paralleled to both at once, or if it's sent
to one control unit which relays it to others. Speed signals are sent
to the ABS, speedo (of course), fuel ECU, transmission ECU, climate
control, and radio. (And maybe some others I can't think of now.) I'm
not sure how it's all interconnected, but I seem to recall when I was
mucking about with my radio, the speed signals for the radio and climate
control came from the instrument cluster.

I just dug out my wiring diagrams manual. The ABS sensors send their
signal to the ABS control unit only, the ABS control unit sends a signal
to the instrument cluster. The instrument cluster then sends a signal
to the cruise module, the engine control module, central lock/alarm
module, radio and RTI (road traffic info) module. I guess the
transmission module gets whatever speed info it needs via the engine
control module. The climate control module doesn't seem to get any
speed signal.
