2001 Chevy Tahoe ABS Code C0265

Cause: A poor connection at the EBCM ground. The EBCM Ground is located on the frame beneath the driver's side door. The EBCM Ground can be identified as the heavy(12-gauge) wire.  Try to clean the ground and tighten with washer and nut to see if you can fix the problem.  Good luck.
