Getting Service ESC- U0073
changed to pedders springs but found one of the abs connectors loose and not to the post
do i need to replace that?
also had the tcm/bcm cable not locked
fixed all that and still got the U0073 code
anyone have this problem and what fixed it
my mechanic is going to research it and see what he can figure out

The Tech II manual says the following modules can set a U0073 code on a GM vehicle. The code itself indicates a "Control Module Circut Bus" problem has been found, usually through a reference voltage being out of range.(loose connections will do that)
BCM, DRR, EBCM, ECM, HVAC IPC, PSCM, Radio, RCDLR, RSA, SDM, TCM, TDM, and VCIM.
"It could be something as simple as a loose electrical connector, low voltage situation, blown fuse or complete failure of one of the modules."
I'd say that having the TCM/BCM cable loose and not locked fully into engagement would be the most likely culprit CJ.
Once that problem and the loose ABS connector are rectified, clear the codes and wait for a recurrence, I bet that it won't return.

we secured the tcm/bcm cable cause it was not locked
i am going to call and see how much a sensor is for the front drivers wheel since it was just hanging there and moving around
he out it on w a ziptie last night and i was hoping it would have fixed it

The ABS sensor is integral to the Hub/bearing. What does "and not to the post" mean?
If the Wheel Speed (ABS) sensor was disconnected you should be getting lots of lights on your dashboard.
