SOURCE: abs codes co281 & co265
the first of the two codes is for the brake light switch, the one that is under the dash attached to the brake rod and brake peddle. Not much to diag on that one, if its bad it's bad, and when it sets the code that means it's bad.
The second one is for the abs modual, it's under the truck on the drivers side. It is bolted to the top of the thing that has all of the brake lines going to it. MOST all of the time that code is set the modual is bad. It can be a little hard to get the bolts out they are torqs 20 or 25(i'm getting old). There are four of them holding down the modual. There are also a couple of connectors going to it. And some of the time it will blow the fuse for the abs under the hood(its in the underhood fues block). Make sure to clean off the modual before you pull it out. You don't want dirt getting in the solinoids for the BPMV(that's the thing it's bolted to).

Hello, your EBCM is located on the frame underneath the vehicle just below the driver's seat. Sorry, I don't have a picture of it. Have you had brake work done recently?

looks like you need an ebcm. You can check the ground under the drivers side door attached to the frame, make sure it is clean and tight.
DTC C0241-C0254 or C041-C054
Circuit DescriptionThe ABS relay supplies battery voltage to 6 valve solenoids. The electronic brake control module (EBCM) microprocessor applies the grounds needed to activate each solenoid. The low side of each solenoid coil has a feedback circuit to the EBCM microprocessor. When a solenoid is commanded OFF, the feedback voltage is high. When a solenoid is commanded ON, the feedback voltage is low.
Conditions for Running the DTC • The ignition is ON. • The vehicle speed is greater than 6 km/h (4 mph). Conditions for Setting the DTCThe EBCM detects an internal malfunction.
Action Taken When the DTC Sets C0241, C0242, C0245, C0246, C0251, C0252, C0253, C0254If equipped, the following actions occur:
• The EBCM disables the DRP/ABS. • The ABS indicator turns ON. • The red brake warning indicator turns ON. C0243, C0244, C0247, C0248If equipped, the following actions occur:
• The EBCM disables the ABS. • The ABS indicator turns ON. Conditions for Clearing the DTCThe conditions for setting the DTC are no longer present and you use the scan tool Clear DTCs function.
Diagnostic AidsAn intermittent open/shorted solenoid DTC can be set by several different internal EBCM problems. Replace the EBCM if an open/shorted solenoid DTC continues to set intermittently.
Did you perform the ABS Diagnostic System Check?
Go to Step 2
Go to Diagnostic System Check - ABS
Go to Step 3
Go to Diagnostic Aids
Important: Following EBCM replacement, use the scan tool to perform the Tire Size Calibration procedure and the Trim Level Calibration procedure, if applicable.
Replace the EBCM. Refer to Electronic Brake Control Module Replacement .

The EBCM detects a low brake fluid condition and sends a class 2 message to the IPC.
The IPC performs the bulb check.
An ABS-disabling malfunction also disables dynamic rear proportioning (DRP).
The IPC illuminates the ABS indicator when the following occurs:
The electronic brake control module (EBCM) detects an ABS-disabling malfunction. The IPC receives a class 2 message from the EBCM requesting illumination.
The IPC performs the bulb check.
The IPC detects a loss of class 2 communications with the EBCM.
sounds like you have an intermittent problem for now ! a wiring issue or wheel speed sensor going bad. Need to check for codes in abs module , that will give you an Idea where to look first. These systems can set a lot of codes, component codes , wiring codes etc... need to know what code first.
