You need to display your DTC data. If you don't know how to do it go here ....
https://www.corvetteforum.com/techti...D=26&TopicID=1
When the AUTOMATIC display completes it will enter MANUAL mode. In that mode display and write down what codes you have.
A code looks like this ...... P 1234 C
The first letter will be either a P, B, C, or U ..... indicating which system the code is for.
The following 4 numbers are the code
The last letter will be a C or an H (sometimes both).
Post the ENTIRE code (as in the example ..... P1234C), and list ALL the codes found.

The C1214 is the "kiss of death" code for the EBCM ..... however, we have some options here.
First, you need to clean ground points G103 and G108.
G103 is located close to the EBCM on the left frame rail and G108 is located on the right frame rail behind the main battery ground under the battery.
See Bill Curlee's "electrical" sticky at the top of this forum for more information on cleaning the grounds.
After you have cleaned both grounds, clear the code and drive the car. Hopefully the problem will be gone.
If the code returns, then you have two choices ... a smart one and a stupid one. The stupid choice is to go to the dealer and get a new EBCM .... which will cost you about $1,000.00 and install it in the car.
The other choice is to disconnect the EBCM and ship it off to this place .....
http://www.absfixer.com
The charge is $150.00 and the unit will come back to you fixed and guaranteed to last longer that the new GM part.
The car can be driven with the EBCM removed. You will not have safety aids such as ABS, but then you don't have them now. Also the steering will feel different as the EBCM also controls the Magnasteer system (variable power steering).
When the ECBM comes bach, the C1288 may or may not have been fixed. If it isn't, it is related to the Steering Wheel Position Sensor and can be dealt with then.
All the other codes I'd recommend you delete and let's see if any of them come back.

Do you have to remove battery to get to this ground 108? Thanks

I'd recommend it, makes it MUCH easier to see what you're doing .... Since you should disconnect the battery anyway (remember disconnect NEG wire first, reconnect NEG wire last) it's 20 seconds more to pull the other cable and lift it out. Also a good time to inspect the battery for any leaks and look at all the wiring and tubing in the area under the battery.

OK, couple of things to keep in mind.
* The Corvette is VERY sensitive to grounding issues. Most cars have a metal frame and a metal body. Install an electrical device and all you need is one wire to it .... the positive wire, because practically anyplace you mount the device is metal and is the car's ground. The Corvette is basically a metal frame and a plastic body. Almost anywhere you mount an electrical device you need two wires .... the positive and then the ground wire that then connects the device back to the frame (ground). If a ground point gets any corrosion or is loose, it will affect multiple devices as there are not that many ground points in the car.
* The Corvette is a collection of computers that control virtually every function in the car. Computers are VERY sensitive to voltage problems, and poor grounds or connections will cause all kinds of problems.
* Finally, the C1214 indicates the following .... there is a relay internal to the EBCM that the EBCM computer uses to supply power to the BPMV (the pump that actually generates brake line pressure for use when the ABS or other functions are operating). The C1214 indicates that the EBCM is sensing that there is no power to the BPMV. That connection to the two is "internal" .... it is almost impossible for the "connection" to be bad .... BUT a bad ground would cause the same symptom ... no power flowing through the relay.
* Last, if it is a bad ground, and you send the EBCM out for repair, or replace it, the saame problem will still be there because the ground wire (which has a clean attachment to the new EBCM) will still have a bad connection at the frame.
So, trust me, clean those two grounds .... it MAY fix the problem, and only costs you some time and elbow grease. If it doesn't ... we can go from there .... but you'll basically be loooking at sending the EBCM to absfixer where they open up the EBCM and replacee the relay with a working (and better quality) relay.

Yes, the EBCM controls several functions in the car, including Anti-lock braking, Traction Control, Active Handling (if equipped) and even controls the Magnasteer system (variable power steering assist).

The BPMV is the unit you can see below the alternator and radiator hose ... it has about 6 brake lines (you can see a couple of the metal lines in the picture) coming out of it. Attached to the side of the BPMV is the EBCM. They are so tightly linked they look like a single unit.
The EBCM (Electronic Brake Control Module) is the computer that makes all the calculations for Anti-lock braking, Traction Control, Active Handling, and other functions, based on input from several sensors in the car.
The BPMV (Brake Pressure Modulation Valve) is the "muscle" of the EBCM. The BPMV contains valves and a pump that are commanded by the EBCM to increase/decrease brake pressure to each individual brake caliper.
The ground points are places on the frame where ground wires can be attached. Bill Curlee's electrical sticky at the top of this forum explains them further, and includes photos of some ground points. What you need to do is inspectt the G103 and G108 grounds for poor connections. The problem could be corrosion, rust, a loose wire ... whatever.

and all the other codes i listed on this thread are they fine?>is it just the abs/traction control thing that i need fixed? i cleared all the codes but one of the t/c codes want clear it pops right back up...so i guess its time to send the ecbm or w.e its called out to get fixed
