I believe this is the case , I learned more about how the system interacts with the PCM accidently .

Yesterday while trying to trouble shoot it I pulled out the CAB and tried to open it up , which was unsuccessful. I gave up tryingto open it without damaging it and just tossed it on the front seat of the truck and cleaned up to go out to dinner. This morning I went out in the truck and noticed the ABS light was still on , same as if the fuses were pulled , but this time the brake warning light was also on , it's never been on other than during the cluster self check, but I suddenly noticed that the speedo was not reading , what the ?? I did pull the rear end sensor to check for debris or damage but I never unplugged it , once I got to a safe place to stop I reinstalled the CAB unit , the speedo is now working again and the abs light and the brake light are on solid, I did not reconnect the solenoid unit. when I got to where I was going I reconnected the solenoid unit and the brake light went off and the abs light was once again flashing. This is telling me the solenoid is good and the CAB is the problem.

Now to find another cab and hopefully not have to pay a dealer 152 dollars to reset the rear end and tire size codes .
