My '01 V70 XC has a great cruise control unit, but sometimes when, after
turning on the cruise control control but before setting the speed, the
unit will trip off when you touch the set control (the "+" switch).
Then the cruise control cannot be turned back on with the cruise button
unless you shut the ignition switch off and then back on. The cruise
does this about once or twice a week. It seems to be a random event
that only occurs when attempting to set the cruise. It does not occur
when using the "+" switch to increase the set speed or when using any
other switch.
I have gotten so I can put the transmission in neutral, turn the
ignition off and back on, and restart the engine without slowing down or
stopping, but I would like to get this fixed. I am afraid that the
dealer will just start throwing my money at it like he did when I needed
a pnp switch on my 850's transmission.
I suspect it may be a software problem. I am guessing that the cruise
operates off the main computer. Any hints to help me limit the good
stuff the dealer will replace in trying to solve this is appreciated.
