2002 Yukon ABS Issue - EBCM?

I have a 2002 GMC Yukon XL. A while back after a long drive a motor would not quit running. It was decided to be the ABS system. We were told that we could pull the fuse on this device and the motor / pump would quit running and would not significantly affect braking performance under normal conditions. I was also told that the contacts can get dirty and that before I replace the board I should clean them. My problem is that I don't know where it is. Can anyone make sence of this and direct me to the best course of action? How do I clean it - we live back on a very bumpy dirt road that was mud for about 6 months. The ABS light is currently on whenever the yukon is on.
Thanks
David Rowe

This is caused by a stuck relay in the EBCM which is under the vehicle below the drivers seat.

What is the C0265 error code


The ABS EBCM anti-lock brake module is failing causing problems with the ABS pump running constantly, also will drain your battery.
  1. Remove the ABS fuse to prevent ABS motor burn out.
  2. You can still drive your vehicle with the module removed.
  3. We recommend covering the exposed surface of the hydraulic control unit with aluminum foil to keep out water and dirt.
Common Failures:
  • ABS Pump Always Running
  • Codes: C0265, C0267, C0268
  • Pump Motor Circuit trouble code
  • Power Relay trouble code
  • Valve Relay Trouble code
  • Dump Valves (solenoids) trouble codes
  • No Communication
  • Intermediate power loss

I HAVE A CODE C0265 ABS BRAKE. IT SAYS BAD GROUND CHANGED BOTH HELP? 2003 YUKON XL


GM states this code is for the ebcm electronic brake control module, I have replaced alot of these over the years the motors short internally and the entire assembly must be replaced. sometimes the main abs fuse will pop and you replace it only for it to pop again because motor in side is shorted to ground.

My anti lock brake light and my brake light stay on. I replaced the abs relay and still has problem. My daughter locked up brakes and spun around on the freeway and I think it is the EBCM


Sounds more like you have a caliper sticking or the lock up caused another issue. Double check the master cylinder and test the splitter module. It should not have locked up the brakes on the highway. ABS is supposed to reduce that from happening. This usually occurs when teh splitter module malfunctions.

ABS light and pump


after you took the fuse out and it stopped did you put the fuse back in and see if it continued to run?

EBCM


No, absolutely not, although the EBCM might possibly be the problem, it is a costly item and 95% of the time is replaced for nothing. Make sure to get the system diagnosed properly, if he can't get a reading from the diagnostic machine, check the abs (EBS) fuse(s), it (they) might be burnt. Then check for fluid level and fluid leaks in the brake system. If these are OK, get the wiring checked to the EBCM for powers, grounds, and data (diagnostics).
