I saw your YouTube video on this procedure. Is it really just that simple?
I bought a used ABS Module (not the pump, just the black plastic Bosch unit) on EBay. I am thinking about removing the malfunctioning one from my car and bolting up the used module.
All diagnostics indicate the possibility of an electronic issue.
Anyway, my only question is, will this do any harm to my car? Note that I can drive it without the ABS system working.

Good morning,

Driving without ABS protection is possible but not recommended. It will not harm the car.

As far as the module, why are you replacing it? Who diagnosed it was the failure? If you have a code, tell me the code so I can look it up for you.

Also, after you install the used one, it will have to be programmed to your car. There is a VIN number in the old one. It has to be flashed to your VIN number in order to work. Any shop can do this procedure as long as they have the scan tool that can do programming.

Also, the number on the donor must match exactly to the one you are removing in order for it to work.

Thank you very much, Roy. To answer your questions: Commercial garage told me my ABS system needed a part they could no longer get. They didn't provide me with any ABS DTCs and they weren't specific about what was wrong.

So I bought the correct shop manuals for my car and followed the diagnostic procedures in Volume 2. The codes I got were 11 and 23. I just used the ABS blinking light method.

Anyhow, the only issue here is the ABS light stays on. That's it. The brakes work fine and I do not have any Powertrain DTCs showing up on my own cheap little scanner.

Thanks again,
Eric

Okay, I attached possibilities for the 2 codes. 12 is the one I am concerned about. It s for the ABS relay which provides power to the solenoids inside the ABS unit.

It looks like they shot from the hip with this one. I think more diagnostics need to be done to be sure the module is actually bad.

I should have mentioned this before: I don't have the traction control type of ABS system. It is strictly the anti-lock braking type without trac control. Sorry. But I agree that more diagnostics should be done before changing the module. In fact, given the need to program any new/used module (flash) I am dependent on a garage with the equipment and the skill.

Thanks again,

Eric
