underdog2k Posted May 31, 2007 Report Share Posted May 31, 2007 Any idea if there even is a VSS wire? Quote Link to post Share on other sites
silverback Posted October 15, 2008 Report Share Posted October 15, 2008 I may be able to help you find the VSS wire (if there is one...) I have access to Volvo factory diagrams. Do you know if the F90 can be installed in the XC90? Have you already done it and just need to locate the VSS wire for the nav? Do you have all other functionality otherwise? Checking out for the day now, but will check for your answer tomorrow. Later Quote Link to post Share on other sites
underdog2k Posted October 21, 2008 Author Report Share Posted October 21, 2008 I have the Z1, and have all functionality except for the dim w/ headlights, and VSS wire. It still works OK without the VSS, but it should be more accurate with it. Quote Link to post Share on other sites
silverback Posted October 23, 2008 Report Share Posted October 23, 2008 Sorry, I cant't help with the Z1. I thought you were working with an XC90 Quote Link to post Share on other sites
ryan420 Posted October 23, 2008 Report Share Posted October 23, 2008 whats the difference all he needs is the location of the vss wire. Quote Link to post Share on other sites
underdog2k Posted October 23, 2008 Author Report Share Posted October 23, 2008 Yes, I do have a Volvo XC90. Quote Link to post Share on other sites
silverback Posted October 23, 2008 Report Share Posted October 23, 2008 So far, info is very muddled about VSS or wiring. This vehicle uses CAN bus for a lot of its data handling and there may not be a wire specifically for a VSS. I just found a sensor on the transmission output shaft housing that looks like a VSS but it's in the parts diagram--now I gotta try to find it in the service info for a wiring diagram. Will let you know... Quote Link to post Share on other sites
silverback Posted October 23, 2008 Report Share Posted October 23, 2008 OK. There is a sensor on the transmission output shaft housing for the the left front drive axle. Volvo does not identify it as a 'vehicle speed sensor' but calls it an 'output sensor'. I'm thinking that's the same thing--it looks like it's reading the front drive axle speed. The wires go to the transmission control module (TCM). There is a yellow wire and a black wire and it looks like the easiest place to access the wires is going to be at the trans output shaft housing. Don't believe I would try to get into the wiring to the instrument panel/driver information module (DIM). Hope this helps, but I'm not sure it's worth it. Let me know.

gtsdohcvvtli Posted October 24, 2008 Report Share Posted October 24, 2008 I would like to know how you got am/fm reception and got around the M.O.S.T system (fiber optics) Quote Link to post Share on other sites
underdog2k Posted October 27, 2008 Author Report Share Posted October 27, 2008 Whew, that sounds pretty rough. I'd actually be more interested at this point in finding a 12V source for night time. The headlights always stay on, but the dash console lights up only at night. Is that only part of the CAN, or can I tap somewhere? gtsdohcvvtli: There is absolutely no good way (or there wasn't a year ago) to get into the MOST system. So, I completely bypassed it. The only thing copper wire in the system is from the amp to the speakers, so I took my output from the Z1 and cut straight to the speaker wires. I was advised to keep everything fiber connected, so the 6 disc CD changer and all buttons are actually still connected and hidden. The MOST system freaks out if something is disconnected, so you actually must disconnect the battery before disconnecting any fiber units. Let me know if you need any more info. Oh, and someone gave me a powered AM/FM antenna, but it hardly works, and I listen to XM and the Z1 Library anyway. I've always wondered about an adapter they sell at Circuit City for Volvo cars.

underdog2k Posted November 24, 2008 Author Report Share Posted November 24, 2008 I know... I just wish it wasn't so darn expensive. Quote Link to post Share on other sites
