ABS module programing
The ABS on my 2004 Silverado 2500 showing codes indicating a pump failure. I can get a re-manufactured control module, but it appears it will need to be programed. which so far it seems my options are:
- Buy a j2534 pass through module, software, and 3 day access to the program and do it myself.
- Take it to a shop - they said dealer only
- Take it to the dealer - they said a re-manufactured module can not be re-programed.

Try contacting SJ Auto Solutions on Facebook - I heard about them on a podcast and they can supposedly source & pre-program modules.
I haven’t had the need to use them yet so I don’t know what all they offer module programming for.

Thanks, the GM parts direct part is a re-manufactured and states it requires reprogramming. The local auto parts store has Doorman re-manufactured that say plug and play. So I am going to install the Doorman and see what happens.

I repair this type of modules, just did a 2002 HD, the hardest part is working on the brake lines. If you cant get the 4 top screws out of the module the complete unit has to be removed and brakes re-bleed. There's no programming required.

Also make sure the module motor works, as it should, as it can cause a problem with the ABS relay failing. You can check the motor by unplugging the motor plug, from top of module, applying 12 volts and ground to wires and measure amp draw. If the motor, only, is bad it can be changed out without removing the complete ABS module assemble by bending or cutting the rear most support motor bracket , I used a Sawzall to cut the end support and removed the two 7mm screws holding the motor to the assemble, pull back motor. When I re-install the new motor , I used the two 7mm screws to hold it and not re-attach the cut off part, it could be welded back on if required.

I imagine it's not so much reprogramming required, as you need to bleed the ABS system, which is done easiest using a scan tool that can command the ABS system.
