VSC / ABS / BRAKE lights 2013 4.0 - narrowing options

Aight so my dashboard is as lit as your uncle on Christmas. VSC/ABS/BRAKE. Took it to the only shop in town that can read the ABS module. They said it was throwing codes for 1) steering angle sensor and 2) LR speed sensor. Also said he believed that to mean that 1) the steering angle sensor was good, but my front end was out of alignment causing it to read improperly, thus throwing the code; and 2) bad wheel speed sensor.

I replaced the LR speed sensor and checked voltage at the pigtail. 11.4 volts is what it was reading (within spec). I reflashed the VSC stuff as per instructions found on here after replacement, yet the lights came back on within 100 yards.

I do not believe my front end is out of alignment; even if it were, my front end guy said "that's bullshit" when I told him what they said. I tend to agree with him. I've seen these trucks so far out of alignment that the steering wheel is cocked 30 degrees yet not throwing codes.

I am about to go have the codes pulled again and see what, if anything, changed after having replaced the speed sensor. My question is this: I know a sensor is a sensor and anything can go bad, but, has anyone heard of a steering angle sensor shitting the bed? I never have.

Just trying to figure out where to go from here.

 

Here is how you can check ABS codes yourself.

Check for codes and go from there.

First, connect terminal 4 and 13 of the OBD-II socket (under the dash in front of your left knee) with a jumper wire. (Those are the 4th from the left on the top and the fifth from the left on the bottom.)

Turn the ignition to on. You'll notice lots of flashing lights, but just pay attention to the ABS light. Normally, it should be rapidly and steadily flashing, twice per second. If it has stored a trouble code, it will instead be flashing a pattern that will coding a two-digit number. There may be more than one code being flashed out. It will just repeat the code over and over, so you have plenty of time to figure it out and write it (them) down.

NOW you can clear the codes. Just tap the brakes rapidly 8 or more times,about two taps per second. You don't have to jam on the brakes, just tap them enough to blink the brake lights. Ifyou're successful, the ABS light should return to its normal fast blinking. Now remove the jumper wire, and finally turn off the key.

Now when you turn on the key, the ABS light should just do its normal light for three seconds and go off. If it comesback on, you still have a problem

As for the sensors, they’re different side to sides. LF and LR are the same. RF and RR are the same. Trying to swap sensors there’s the possibility of breaking them when you try to remove them.

I’m pretty sure it’s possible to swap the rear harness connectors at the axle. I think they’ll reach the wrong side. Swap them, attempt to clear codes and then see if you get a code for the other side. Obviously don’t go out and do a panic stop with the harnesses swapped.
