Corvette CCM Reverse Engineering Anyone?

I wonder what "Allow TCC control and DC" means on Bit 1. I also wonder why the CCM would need to know something like that?

DC would be referring to duty cycle for either the TCC pwm solenoid or the EPC solenoid.

My only guess as to why - possibly information relevant to a 4wd body control module?

Before a location in the EEPROM is written (programmed), it should be erased
to assure that all bits in that location are high....

Where are you reading that at? I only ask because I've zeroed bits without erasing the byte first and it worked as expected.
