'99 V70 XC here.
So the other day the car wouldn't start. Or rather, it would start, would run for a second or two and then would die. Well that's a fuel issue thought I. Did a little reading, jumped the 15 and 87 contacts and it fired right up and worked just fine. Read that the electrolytic caps often fail so I soldered in some shiny new ones and put the module back in the car...and same problem. Harumph. Must be the coil in the relay that has failed.
Well, I was just about to head off the the dealership when it occurred to me that I never actually tested across contacts 31 and 31b. So I grabbed ye olde multitester, shoved those pins in there, and not a thing. Double Harumph!!! Putting he multi-tester across pins 15 and 87 and it reads 12V the moment the key is turned, so apparently I replaced those caps for nothing.
Now I'm puzzled. What's the next stop for the diagnosis train?
