extrich Posted December 9, 2006 Report Share Posted December 9, 2006 Anyone out here know what these codes mean, I recently have aporblem with my driver side abs pushing back at me on light braking. I ran a diagnostic and got these two codes. 1. P1571 traction control system PWM circuit no frequency 2. P1689 traction control delivered torque output circuit. I would appreciate to find out what they mean and hw to rectify. Thanks Rich Link to comment Share on other sites More sharing options...
Cadillac Jim Posted December 9, 2006 Report Share Posted December 9, 2006 Here's what I have: P1571 Traction Control Torque Request Circuit P1689 Delivered Torque Circuit Fault It looks like one or both wheel speed sensors is disconnected. I believe that these connectors are on the center of the hub on the suspension side of all four wheels. I would also check the connectors and wiring on the rest of the traction control system, particularly to the module (under the Maxifuse block behind the air cleaner). -- 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.
