This might fix it for you:
ABS Light On, DTCs C0265, C0201, U1041 Set and/or Loss of Communication with Brake Module (Reground EBCM Ground) TECHNICAL SERVICE BULLETIN Reference Number(s): 04-05-25-002E, Date of Issue: March 11, 2009 Affected Model(s): 2004-2007 Buick Rainier; 2002-2006 Cadillac Escalade, Escalade EXT; 2003-2006 Cadillac Escalade ESV; 1999-2007 Chevrolet Silverado Classic; 2000-2006 Chevrolet Suburban, Tahoe; 2002-2006 Chevrolet Avalanche; 2002-2007 Chevrolet TrailBlazer, TrailBlazer EXT; 2003-2006 Chevrolet SSR; 1999-2007 GMC Sierra Classic; 2000-2006 GMC Yukon, Yukon Denali, Yukon XL; 2002-2007 GMC Envoy, Envoy XL, Sierra Denali Classic; 2004-2005 GMC Envoy XUV; 2002-2004 Oldsmobile Bravada Supercedes: This bulletin is being revised to add step 2 to the procedure and update the Parts and Warranty Information. Please discard Corporate Bulletin Number 04-05-25-002D (Section 05 - Brakes). Related Ref Number(s): 04-05-25-002, 04-05-25-002A, 04-05-25-002B, 04-05-25-002C, 04-05-25 -002D, 04-05-25-002E ARTICLE BEGINNING CONDITION Some customers may comment that the ABS light is on. Upon further inspection, DTCs C0265 and C0201 may be set in the brake module. It is also possible for DTC U1041 to set in other modules. There may also be a loss of communication with the brake module. CAUSE A poor connection at the EBCM ground is causing unnecessary replacement of brake modules. IMPORTANT: The EBCM ground is different for each application. Refer to the list below for the proper ground reference: Midsize Utilities = Ground 304 " SSR = Ground 400 " Fullsize Trucks and Utilities = Ground 110 " CORRECTION IMPORTANT: Do not replace the brake module to correct this condition. Perform the following repair before further diagnosis of the EBCM. Perform the following steps to improve the connection of the EBCM Ground: Remove the EBCM Ground. The EBCM Ground is located on the frame beneath the driver's side door. If multiple grounds are found in this location, the EBCM ground can be identified as the heavy (12-gauge) wire. 1.

Or this:
Intermittent StabiliTrak Indicator Light Blinking, StabiliTrak Active Message Displayed, DTC C0196 Set (Reprogram Electronic Brake Control Module (EBCM)) TECHNICAL SERVICE BULLETIN Reference Number(s): 08-05-25-005, Date of Issue: October 01, 2008 Affected Model(s): 2006-2007 Buick Rainier; 2006-2009 Chevrolet TrailBlazer Models; 2006-2009 GMC Envoy Models; 2006-2009 Saab 9-7X; 2006-2009 Isuzu Ascender Models Related Ref Number(s): 08-05-25-005 ARTICLE BEGINNING CONDITION #1 NOTE: This bulletin provides information on two different conditions. Some customers may comment on a Service StabiliTrak indicator light along with a Service StabiliTrak message displayed in the DIC. Upon investigation, the technician may find DTC C0196 set in history. CONDITION #2 Some customers may comment on a blinking StabiliTrak indicator light along with a StabiliTrak Active message displayed in the DIC during normal driving conditions. No DTCs will be found with this concern. CAUSE This condition may be caused by a software anomaly within the electronic brake control module (EBCM) that allowed the yaw offset to be falsely learned. CORRECTION Correction Do This Don't Do This Reprogram the EBCM. Do not replace the yaw sensor or EBCM for this condition. IMPORTANT: From the controller list, select "VSES Vehicle Stability Enhancement System Control Module." If routine diagnosis using SI does not reveal any obvious cause, reprogram the EBCM using SPS with the latest software available on TIS2WEB. Refer to the Service Programming System (SPS) procedures in SI. As always, make sure your Tech 2 is updated with the latest software version.
