"Service Brake System"
I have a 2003 Chevy Duramax, and recently the "service brake system" message has been coming up on the DIC but my brakes seem to operate fine and there is the right amount of fluid in the reservoir and no leaks.
The "service brake system" along with about 7 dings, will sometimes happen right when I start the truck, but for the most part it happens at about 70km/hr, the ABS and Park Brake light will both come on, and then shortly after it will all go away, sometimes it wont come on for a half hour sometimes it will happen within 5 minutes. Also my Speedo will get a little bouncy around 100km/hr, and if i have cruise control long enough it will just stop working. Help!!!

mine does the same thing but not sure why. with the speedo, you might have the stepper motor going out.

Does it show any wheel speed sensors failed in DTC/code reader? If so, clean or replace and try again. I had one get dirty on my other truck.

I am having the same "service brake system" error as you are. I came across this fix on another forum. I haven't had a chance to try it yet but it is worth a shot.

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).
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 U 1041 to set in other modules. There may also be a loss of communication
with the brake module.
A poor connection at the EBOM ground is causing unnecessary replacement of brake modules.
The EBOIV1 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
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:
1. 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.
2. If the original fastener has a welded on nut, remove the nut from the frame, and if required, enlarge the bolt hole to accommodate the new bolt and nut.
3. Clean the area, front and back, using a tool such as a *3M(TM) Scotch-Brite Roloc disc or equivalent.
4. Install the ground, then the washer and then the bolt to the frame.
It is important to use the bolts, washers and nuts specified in this bulletin. These parts have been identified due to their conductive finish.
5. Install a washer and nut to the back side of the frame.
Tighten the nut to 9 Nm (79 lb in).
6. Cover the front and back side of the repair area using Rubberized Undercoating.
An additional check can be made to ensure a good connection for the battery cable to frame ground. It is possible for this ground to cause similar symptoms with the ABS as described above.

i had the same issue. i didnt have power coming to the fuse panel under the hood for some reason. The box itself was shot, snapped the old one out, and put the new one in, and its working like brand new.

mine did the samething this weekend after installing the PPE stage 2 tune. Within 1 mile of the house the abs light came on with the message "service brake system."
All I did was install the tune, and raise the speed limiter from 98mph to 120mph.
Anyone know what is going on here?
