Question about 2003 GMC Yukon XL
C0550 is the code for the ABS module. It is on the frame under the vehicle around the drivers door area. It is a module with all the brake lines coming from it. Reset the trouble codes and see if the problem returns. If it does, the module is not serviceable and will need to be replaced.

I have a Yukon xl 2002 and there is a noise that stays on even after the vehicle is turns off. Now the brake light is also on. Can you help and do you know about how much it would cost.
