Apparently my EBCM is bad, which I find odd considering my car is a garage queen with only 16K miles... guess that doesn't matter with crappy GM electronics! Anyway, purchasing a new unit for $750+ is a bit out of the question when chances are I'll just run into the same issue later on. Looking at the ABSFIXER site, it says something about "will not fix C1214". What does that mean? Am I going to be stuck with that code even after repairing my module? I know there are some other options for repair that are cheaper, but just wanted to get the skinny on that code. I really need everything to work with no lights as it should.

It maybe just stuck. Have you done a search on it here? Some have done the hard stop fix in a parking lot and the issue went away.

Mine came on and I done the jacking of rear tires and the hard stops. My code went away.

I saw that somewhere. I'll be glad to try it, is there a defined process that is recommended?

All I did was go to a large open space parking lot and did sudden stops from 30 mph then 40 mph and then 50 mph. Took several attempts. After about 45 minutes and explaining to the cops what I was doing I cleared the code and left. Since that day my code has never came back.


I tried the jacking rear tires but that did nothing.

It been a year and still no code.

I'm sure I won't be so lucky! I'll try ... And sudden stops as in locking up the brakes and skidding?

bravo29

Yep

Do it on a wet surface or a dirt road so you don't flat spot the tires

I think you read it wrong or something. ABSFixer is specially for the C1214 code on C5s.

I had this code and fixed it myself. If you can solder, you can fix it for free. A few solder joints on a power relay go bad. Very common issue.

My C1214 was very intermittent and then one day it was dead for good. I'll bet yours is on it's way out. When it goes, you won't have active handling, ABS or traction control.

BTW the condition to set this code is "The system voltage is less than 8 volts for 0.23 seconds."

Doing hard braking or whatever it not related whatsoever.

10-4, it might have been another repair site but I can't find it now. Whichever one it was said it would not fix C1214. Anyway, we are going to try the repair as soon as I find a new relay to put on . Btw, car is a 2002 Z06, getting code C1214 and AbS/Traction are not working. Have already done testing at the wheel sensors .

Can someone help with the relay part# for the 2002 EBCM? The thread that shows the DIY fix has an "obsolete" part number that comes up on digikey .

aaronc7

This guy says he thinks he found it and said he would report back, but did not. Specs look the same to me.

The manf. part number is ORWH-SH-112D1F,000. The Digi-Key number is PB2029-ND.

Thanks! I ordered a few...

The Code C1214 is due to the electronic is receiving less then 8 volt from the system relay in the EBCM . This can be caused by a blown fuse , bad grounding , bad soldering points on the electronic card or faulty system relay( wihite relay shown below) .
I would first checked the fuses and cleaned the ground terminals G103 and G108.
With some soldering skills it possible to change this relay by yourself , relay costs only a few dollar .
After this the code shall disappear

GM's cheap,did they use this ebcm on any other cars/trucks ?

or parts of it?

lets get some pics of the unit up and any serial/part numbers,how many hard brake lines,and what the plug looks like

Ok, I was confused and put C1214 by mistake (too much reading about EBCM issues)... It's actually code C1232 that I'm getting. We have now replaced the relay on the EBCM, which may not have needed it anyway but didn't hurt for a couple bucks. I don't see any broken solder joints on the board and we tested the wheel sensor readings. The car is a 2002 with only 16K miles (garage queen). All ground locations look NEW as you would expect.

You can disconnect the left wheel speed sensor and measure the resistance between A & B on the wheel speed sensor connector , should be 850-1350 ohms .

From everything I've read about ECBM issues, yours can be repaired by ABS Fixer. The '00 and older ones cannot. I understand the repair is not that expensive (something like ~ $150)...

We checked that, see my other thread here: https://www.corvetteforum.com/forums/c5-tech/4219859-c1232.html
