kbrkr Posted September 19, 2018 Report Share Posted September 19, 2018 Obviously, I did not install the speed pulse wire during my installation as I had a hard time finding the correct wire in my Porsche. I'm starting to get this error; "Calibration will start, but may be inaccurate without speed pulse." Whenever I use the Navigation. When the error is present, the NAV screen is unresponsive. It has to timeout on it's own. Anyone have a workaround? Quote Link to post Share on other sites
kbrkr Posted September 21, 2018 Author Report Share Posted September 21, 2018 This message is becoming a problem as it remains on the screen blocking the actual MAP for the entire journey and I can't find a way to clear the message. Any Ideas? Quote Link to post Share on other sites
onebyside Posted September 21, 2018 Report Share Posted September 21, 2018 Lots of info when I search speed pulse. Quote Link to post Share on other sites

Any Ideas? Maybe if you stated the model and yr someone could tell how to connect VSS to a pulse wire. Hint - it is in your ABS harness below the brake fluid reservoir. Probably White/Brown for Porsche. Quote Link to post Share on other sites
kbrkr Posted September 23, 2018 Author Report Share Posted September 23, 2018 Yes, thanks. It's a 2013 Boxster. According to my wiring diagram, White/brown is Terminal 31. There are 4 wheel sensors coming from the wheels into the PCS control unit, but I can't find them. Quote Link to post Share on other sites

I have printed instructions from the EuroMotorSpeed kit. It says to remove the cover over the brake fluid reservoir and you'll find a black 46 pin connector with all the wires for ABS. On mine, it was the BRN/WHT wire going to pin 19. Your's looks different. Basically, any wire that pulses when any wheel rotates will work. Quote Link to post Share on other sites
kbrkr Posted September 24, 2018 Author Report Share Posted September 24, 2018 Thanks Ron, yes this diagram came from my 981 2012-2015 Service Manual. Thanks for the tip on the Brake fluid cover, I don't think 987 is that different from the 981, it should be in the same location. Many thanks for your help. Al Quote Link to post Share on other sites

Al Pin 38 in your wiring diagram looks promising. I checked my 987 diagram and it looks comparable to my pin 19 (both BRN/WHT and go to a module on the right side of the frunk). To access you'll have to remove some of the liner plastic trim. Probable just held by a few screws. Quote Link to post Share on other sites
