Thread: anyone smart on abs???

more then likey you got a bad one

it could be muitable things but theres no way to just change whats wrong, you have to get a whole part to fix it and if its throwing a code for the module you just have to replace that part...you could test it if you had a scanner

go on gpona.com and look up the diagnostic chart for the code and follow that.

The code is showing b0550 "electronic control moduel malfunction". so I bought a used one and installed it, and nothing changed cleared the code and it comes back up with the same code. Checked my powers and grounds in the plug going to the moduel and everything is doing what it should.

Could of I got a bad moduel? or is it something else? do the pumps go bad on these?

Is there any gm techs or guys that know more about my problem that are willing to give me any advice?

Thanks for any help

if you bought it from a junk yard, it should have at least a 30 day warranty. and im sure they would replace it for you. they dont want the rep of selling bad used parts.
