Default Wheel speed sensor? 09 H3 Base

Hopefully this is a quick question. When I make left turns, I am getting the blinking TCS light and engine stalls for a second or two. It never happens when driving straight and very rarely on right turns. I am hearing clicking in the dash when I am braking at around 20MPH then the brakes will grab a bit harder for a few seconds. No codes but I scanned it with a scanner that will do ABS. It showed a "fault" in "Vehicle speed circuit 2". I replaced the passenger side wheel bearing and sensor thinking it would be #2. No change. Could speed cicruit 2 be referring to the driver's side?

What is the exact code you received?

"Vehicle speed circuit 2" mentioned does not sound like an ABS wheel speed sensor malfunction. More like the speed sensor in the Tcase.

Please take the time to back probe and DVM each wheel speed sensor.
it is pretty straight forward.
Also verify wiring harness at wheels.

Thanks. I'll try the probe. If it was the sensor on the TCase why would it show up mainly during left turns?

Why not post the actual code so we can help you further and stop guessing?

It's not giving me a code. I wish it were.

You need to use a scanner capable of scanning all modules, not a basic code reader.

I'm using an Autel MX808 scanner. It showed a "fault" for the ground test, open test, and short voltage test on Vehicle speed circuit 2. It also showed a fault for the same TCS circuit tests.

You're unable to retrieve a code? Did you scan abs module? Look for historical codes?
With your symptoms, false tc activation would also cause reduced power, start by checking front wheel speed sensors and steering wheel position sensor, connector/contacts/wiring.

Yoda: Is not the Vehicle Speed Circuit 2 different that the wheel speed sensor circuits. P0500s and/or P0600s codes they would be.

However, if the scan was done while the vehicle was under 600 RPM then only the failure will be stored in memory = no CEL. This might be one of those scan while you drive things?
