4lo / 4hi lights flashing, traction control, vsc, abs solid

While driving my front right tire on my 2007 Tundra 4x4 went off a curb a little hard. About 30 minutes later of driving the above lights appeared on my dash. Anybody have any idea what this could be? I also have an issue where I get a crunching during hard breaking almost like a warped rotor despite brakes being good and wondering if this could be related.

Have done some research and plan to start by checking out cv axels and wheel sensors but wondering if anybody has an idea.

 

You need to pull engine codes, step 1. AutoZone does it for free, a ~30$ Bluetooth OBDI is another step 1 to get started in all troubleshooting.

 

When this happened to me, it was because there was a short in my wheel speed sensor wire.

My suggestion - test the speed sensor wire harness for continuity before buying/replacing the speed sensor. That's what I did, I found the tear in the jacket of the wire - re-spliced it back together and voila, no more issue.

 

That was going to be my guess, speed sensor
