ABS/ Brake light Question

[Doubeleive]

I appreciate the advice. Wasn't sure if the vehicle had to be off, then cycled on or if you could actually run diagnostic while running.

(if it is the abs module) if you shut it off the codes will go away until it faults again, for this type of diagnostic leave it running.

To be clear since I've never used a scanner...if my son comes home from school and lights are on, leave it running and plug the scanner in?

Sorry I didn’t read all the posts to see if this was answered. I had this issue and was able to fix it. You need to remove the abs sensor under the truck and below the driver seat area. Then pry the lid off the unit and you will see a circuit board with lots of soldering. Take a solder gun and solder and touch up all the solder points. I had to do this twice since I didn’t touch all of them. Basically the solder points get brittle and break. Finally using some gasket maker around the lid put it back on and reinstall.

If the EBCM is the issue, there used to be a service on eBay that you could send it to for repair with a lifetime warranty for about $50. I had mine done years ago and still good today.

There are still places that specialize in this.

yes

I have a question about this. I picked up my scanner and to retrieve codes it says ""DO NOT start the engine". Is that just BS, or can I actually mess something up?

ignore that, and scan it
note that the option to scan for ABS is not usually a default, you may have to click thru the menu to have it check for abs or srs since neither of those are OBD codes.

I would plug it in while it’s running, voltage sometimes spikes in the OBD port during the crank cycle. At the very least it shuts off for a second or two.

I apprecaite everyone's input. I'm waiting for my son to get home to do this. I thought when you plugged the scanner in the first time it would ask a bunch of questions like make, model etc. Didn't know if it mattered or not if you plugged it into a running vehicle for its first ever scan

It may give you exactly what you want with it plugged in and KOEO.
