You're welcome GW. Mike knows more about these things than I so I am happy he jumped in.

It might be strange but it is true. Seen a few folks here with that very issue including @Mopar1973Man. The buzzing I think is a sign the module has problem, but others would know better than I.

Most likely the module is running the ABS pump motor. The only thing you have do is remove the screws and pull the module up off the valve body. Then send it to Module Master and let them rebuild the

So when I bought my 01 3 years ago it came with the ABS and Brake light on and although we figured out the brake light being the entire pedal assembly was bad, we never could figure out why the abs light was on and why the module would buzz when plugged in. Fast forward last may doing axle shafts, find out the passenger side hub sensor had been cut somehow, so we replaced that and tried to plug it back on with a buzz still occuring whether the truck is on or off. I gave up on it as I had more pressing things to fix on it. Well quarantine has got me itching to fix something so I figured I'd dive in, and plugged it in and busted out our Bosch scan tool from oriellys, and all I get is "not detected" instead of "no codes". Would this be a bad module? I can't find anything else abs wise that is bad, all the wires are still connected where they're supposed to be. The rear speed sensor male plug's clip is broke but it stays in the sensor and I have a speedo so I don't think that is the problem. If anyone's got any ideas let me know! Thanks!
TL;DR Scan tool yields "not detected" for abs codes yet light is on and module is buzzing constantly whether truck is on or off.
