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.

But again to answer @TheGreatWhite, you can drive without the module, you just won't have some of your gauge cluster or miles working while you get it repaired.

 

Yes you can but...

• Grid heater will not shut off above 20 MPH so be aware. Battery charge time needs to be extended.
• Cruise control doesn't work need to be above 30 MPH to set..
• High idle will work but will not cancel from no speed signal.
• Speedometer will not work. Lack of signal.
• Might impact automatic trans being road speed is considered.
