KenD Posted March 28, 2008 Report Share Posted March 28, 2008 I'm getting code TC0027 and my ABS light is on. Sometimes it will come back if I wash the car or with some stroke of luck. Nice to have 1st gear back when it does come back. It's short lived when it does come back as I get may anywhere from 20 meters - 1km of distance before the ABS light shows. Anyways, i will get the harness looked at, but does anyone know the GM/ACdelco part number? thx ken 1994 STS Pearl White 260,000 KM (163,000 miles) <img src="http://img45.photobucket.com/albums/v137/caesar/caddycaesar.jpg" border="0" class="linked-sig-image" /> Link to comment Share on other sites More sharing options...
Cadillac Jim Posted March 28, 2008 Report Share Posted March 28, 2008 The speed sensor connector for the left front wheel is loose or off, probably. If you need the sensor, it's changeable without a new hub. -- Click Here for CaddyInfo page on "How To" Read Your OBD Codes-- Click Here for my personal page to download my OBD code list as an Excel file, plus other Cadillac data -- See my CaddyInfo car blogs: 2011 CTS-V, 1997 ETC Yes, I was Jims_97_ETC before I changed cars.
