Cadillac Jim Posted September 6, 2006 Report Share Posted September 6, 2006 C0620 - Right Front Position Sensor Malfunction U1016 - Loss of Class 2 Communication with VCM These are suspension system errors. Are they current or history? Do you have any DIC messages? -- 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.

Dasher Posted September 7, 2006 Author Report Share Posted September 7, 2006 Yes, I sometimes have a "check suspension system" message but it comes and goes. I may have it a day or two and then not see anything for weeks. Link to comment Share on other sites More sharing options...
