Having problems with your 2002 GMC Yukon XL ?
EBCM Dear sir I have a yukon xl which i took to the dealer when my abs & emergency parking brake light flashes on & off only when the car is being driven, he told me to st art he would have to change the ebcm so he can get a reading from the abs computer diagnostic machine
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).
