I pulled every code from the car to see what I can do to fix it and/or where I should start

28-TCS C1232 H C
28-TCS C1233 H C
28-TCS C1255 H
28-TCS C1278 H

40-BCM B2723 H
58-SDM B1001 H
AO-LDCM B2252 H
AO-LDCM B2282 H
AO-LDCM B2284 H
AO-LDCM U1064 H
BO-RFA U1255 H
BO-RFA U1096 H
BO-RFA U1064 H
BO-RFA U1016 H
BO-RFA C2120 H C
A1-RDCM B2283 H
A1-RDCM B2285 H
A1-RDCM U1064 H
A1-RDCM B2252 H

the car has the "service abs soon" and service traction control, i've only owned it a few days now and I didn't have an issue until I tried to take off harder than normal and my check engine light came on, i pulled over and got my scan tool and got a p1515 code " Electronic Throttle System Throttle Position" guy i bought it from said tires and brakes are new. i'm thinking maybe some of the codes have to do with eachother but I really don't know so I just listed everything, I mainly want to fix the abs and traction control issue

if anyone can help and point me in the right direction i'd be very grateful.

 

Ok, let's do a bit of triage here.
1. All codes with H following them are historic codes that are not currently setting. This happens for all sorts of reasons. Codes with C after them are currently occurring codes. HC means they both have history and are currently being set.
2. The module here is what you're looking for to narrow down the system having issues. TCS = Traction Control System. Since that's the issue you're currently having, let's focus there.

The absolute VERY BEST way to troubleshoot codes is to go to your favorite search engine and search the code followed by site:corvetteforum.com. This will narrow your search results to threads posted here by members who had the same code. The car is 20 years old. I can almost guarantee that ANY problem you might have with your car has been experienced and discussed at length here.

Step 1 to troubleshooting nearly all electrical issues with the . They're NOTORIOUS for corrosion which interrupts the ground side of the circuit that they are serving. Once you've verified that all your grounds are clean and tightly connected go through and clear all your codes. Drive around for a bit and see what comes back (if any) and then you can begin further troubleshooting from there.

 

good advice above
