Dead battery and warning lights
I left my 50th anniversary out in the rain the last couple days went to start it this morning and the battery is dead. Used a battery charger 2 start the car and warning lights came on. Abs and traction control lights are on now reset button won't get rid of them and tour sport mode button is not working. Went into the d i c and pulled a couple codes:
C1214 C H
C2100 C H
Just spent about an hour reading on the forums about the dreaded ECBM problems.
I see this topic of traction control and abs has been covered quite extensively but any advice on where to start would be appreciated. Thanks

You should fully charge the battery and have it load tested, your battery voltage did not fully come up to 12.5 volts when you started your car with the battery charger. Low voltage conditions will cause all kinds of codes to be set.

My negative battery cable wiggled its way loose. Charged and tested the battery it's good. Replaced battery and checked grounding cable. Warning lights are out now

Abs and service traction control warning lights are back on.
Went in the DIC pulled this code:
BO-RFA. C2100
Also the left front tire pressure has xxx in the DIC
Is this all related to jumping the car with the battery a battery charger ? Am I looking at replacing a TPMS?
Any help here will be appreciated, thanks

The front tires are fairly new so it's going to be a while before I change the TPS inside of it. Guess I'll just drive around without ABS and traction control until that left front tire wears out

The TPS is inside the tire and only reports tire pressure. There is a sensor external to the wheel that gives feedback for the ABS and traction control.

Went and checked a few of the grounds and check for clean connection everything looks good there.
I'm going to run the codes again tomorrow try and get the car out the weather has not exactly been stellar. Will post here at once I have the new codes and thanks again I really want to fix this.

Took the vette out today and did a burnout! Don't get too excited it was just a tire chirp anyway I pulled the code:
C1214 C H
Any other advice before I tear out the ECBM? Or maybe just hit reset every time I drive? Thanks
