Scanner that will display ABS live data

I have a 2009 with 175k. It has exhibited an intermittent ABS fault. Codes from reading the light blinks are 34 which I believe points to the rear left sensor. I suppose it might be a bad ground given this vehicle lives in the NE salt belt.
Has anyone had a good experience with a mid priced scanner displaying ABS sensor live data?
Thanks

 

Pick something from Launch, Autel, or TopDon that does all systems.

Have you checked Connector S22 above the rear axle where the ABS sensor wires connect to the the frame wire? It's a known spot for the wires to break and/or corrode.

 

I’ll take a look at that more closely, nothing obvious when I traced the wiring
Thanks!

 

Corroded wires are pretty common in the salt belt, all it takes is a nick or rub-through in the insulation for the green to set in.

I can grab a wiring diagram but I need to know if you have a hydraulic (TRD OffRoad) booster or vacuum (All others) booster.

 

It’s not a TRD there is a vacuum booster on the master cylinder.

 

After a careful examination the rear axle ABS harness appears un-damaged and shows connectivity, no sign of a ground wire back there. The wire mount on the axle rusted off so I removed it. The nuts that the hold the rear ABS sensors in place are so heavily rusted I’m not going to mess with them for now as it would require new rear bearing housings if the studs break off. So I used contact cleaner and sprayed the heck out of the sensors and connectors(which had green deposits) and plugged everything back in so far that has almost solved the problem. I get just an occasional light now and it usually goes out in a couple of minutes.
Is there a specific ground for the ABS?. The wire diagram shows several. I’m wondering if an intermittent ground due to corrosion might be a contributing issue. Thanks for the assistance!

 

No, all the wires come from the ABS module.
There is no individual ground wire. It's all done through the ABS module.
If it were a ground issue, you'd have a whole different code and set of issues.
