ABS Sensor error, easiest way to diagnose?

[Guyfromthenorth]

I'm in a real tight spot here. There was an ice storm 4 days ago and the rain\ice\salt was everywhere and I popped an ABS error code. This of course meant my cruise, traction control, and most importantly 4WD systems are entirely disabled now. I am moving to a new house 4 hours away and there's 6ft of snow still, ice and ruts everywhere, and I'm having to towing a 5000lb 25ft trailer in that crap without 4WD. I probably can't even get it out of the driveway without spinning even my studded winter tires in 2wd. The houe closing date is this Thursday...

I already pulled all 4 wheels and the sensors\wiring are in place and not visibly damaged. I painstakingly opened each sensor connector and sprayed contact cleaner in them, dried them. reconnected and still got the code. My issue is I just don't want to pull and replace 4 sensors in -20 degrees in the snow just to see if it fixes the issue because my luck would be it turns out to be a wire somewhere along the frame that was the culprit all along. Is there an easy way to at least figure out which sensor run is the problem one? I find it total BS the system can't at least identify on the cluster which tire is the issue because I'm positive the ECM knows or has the ability to know.

Is there a code scanner that could pull that info for me? I'd prefer to avoid paying the $$$ for a professional level Autel unit, but is there a knock off version that can at least read ABS sensor outputs?

I know this seems ridiculous but try replacing the battery. I had a similar problem and replacing the battery fix it.

Go to a local shop, throw the guy $20 (or even $50) and ask him to read the codes on a good scanner. Many parts stores will do it for free, but they typically use entry-level scanners.

See this all the time on Hwy Web Cams. I finally looked it up. It is a salt solution sprayed on the ground to speed up the melting of snow and ice. Described as a brine, and when driven over is pressure blasted into all nooks and crannies of your truck's underbelly. Nothing is spared a generous...

See this all the time on Hwy Web Cams. I finally looked it up. It is a salt solution sprayed on the ground to speed up the melting of snow and ice. Described as a brine, and when driven over is pressure blasted into all nooks and crannies of your truck's underbelly. Nothing is spared a generous coating of this very corrosive brine mixture. It is no wonder cars have all kinds of slow developed accumulated electrical and mechanical issues.

Solution, rinse with a hose after every drive during wintery conditions. Who does that?

A rust preventative coating. I'm skeptical of that being effective. And it sounds costly to do right, requiring a lift of some sorts.

I'm considering this --> (slowly drive over this a few times before putting away into the garage).
