The B2723HC means you have problems with the chip in your ignition key, It is a past and present condition.
The B0605H means your BCM had a problem internally in the past.
I have a 03 Z06 that has been sitting for a month or so. I went out to move it today and it woudn't start. I charged the battery and got it started. I drove it around our community. As I was driving, it went into reduced power mode. When I got it back to the house, I shut it off and looked at the codes. I had probably 12 total codes (including the traction control). I tried to start it again....no joy.
I took the battery out and had it checked. It was bad...After replacing the battery, I cleared out a couple more codes and it runs fine now...no codes, no issues.
Batteries must be charged or else

VERY true!
People have been arguing for DECADES, as to what's the best battery for a C-5 Corvette. Given what I've seen and experienced, a "fairly new, fully charged" (no matter what brand) battery, is the "best" one........
The more I look at this I bet it is ignition switch. There is a voltage issue with the tcs and another low voltage. Anxious to see what happens with a new switch. It also looks like the previous owner used a tech 2 and blocked the f45 shocks
oops wrong thread
