Can RF Throw a Wheel Speed Sensor Code?
For the past year or so I started getting the notorious EBCM 1214 Code as well as a 1263 Rt Front Wheel Sensor Code (usually together) in turn activating the ABS/TC/AH lights.
About 3 weeks ago I had the Dealership replace my EBCM under GMPP - I have not seen the 1214 code since. However, I am still throwing the 1263 code every day or two. What I have noticed is that the 1263 code/ABS/TC/AH lights all appear when I am driving down the same three roads around town at the exact same locations (like every time I pass the Olive Garden Restaurant). I am just wondering if maybe a building alarm system or something may be triggering this?

I agree!!
C1263 is a RF Inlet Valve Solenoid Malfunction. Its either a malfunction in the New EBTCM or the RF Inlet Valve Solenoid inside the BPMV is not working properly.
If it were me, I would find a nice empty safe wet road and stomp the brakes hard enough to activate the antilock a few times and see if you can get the system working.

Yes, just the EBCM.
Sorry, I am an idiot... the code I am getting is C1226 (not C1263). Don't know where I came up with 1263? They are planning on replacing the right front hub on Monday - does that sound right?

Sure it's possible, but they don't go bad often. A careful inspection of the wiring (and eval with a meter) is in order. I guess if it's on their dime....let them play.

:rofl : You would most likely be wasting your money. I have NEVER seen one go bad,,,,,,,EVER!Like Lucky recommended,,,,carefully examine ALL the female connector pins and I bet ya, you find a bad female pin.
Heres an example of a new and a bad female pin in a WSS female connector:
The BAD female pin is on the RIGHT. The new one is on the left.
Heres a picture of the jumper cable. Theres a female connector on that cable to:
Inside a WSS:
Theres also a female harness connector on the K member that needs to be checked.

Here is a copy of one page of the invoice which mentions a "REDESIGNED CROSSOVER HARNESS"? Did they come out with a "new" design for the harness?
