My 2K is showing "Service ABS" and "Service Traction Control" on the DIC. The dealer looked it over and said it's the Electronic Brake Control Module. Anybody replaced one of these yet? If it's plug and play, I can do it myself, otherwise its $745 to the dealer. Any help would be greatly appreciated!

Mine went out...The parts not expensive...but the labor $$$$....It is a plug in do it yourselfer, but thats about it....Once in....the system has to be reflashed....Unless you have the tools needed (usually issued to certified techs only) you would be in good shape...But thats not the case...You would need a certified center that has the proper equipment to do so install it....

 

codes??

 

Plug and play,no programming or reflashing required...

 

Any error codes? I wouldn't just assume it's the EBTCM unless the dealer actually connected up a TechII diagnostic tool and told you that it's actually bad. Mine is doing this too and clears up when I recycle the ignition. Someone suggested that it's the power steering pump. Another suggested that I should have the brake system power bled because air may have found it's way into the ABS system and the EBTCM pump motor stalls due to air in the system. What a PITA...I haven't decided what I want to do next, but just keep driving it while I think about it. I guess when I start getting the reduced power thing going on, I'll be forced to deal with it.

What?? This is not true. The EBTCM is definitely PNP install. Needs to be properly bled after the install. Any codes set can be easily reset at the DIC. No reflashing or special equipment needed. Be sure not to loose any of the cushion grommets that the module bolts to the bracket with.

I had mine done at dealership under warranty. The tech did not reflash my pcm and did it under an hour once the part arrived. Remember to unhook your battery

I have been ALL OVER THIS ONE!!!! My 02 Z06 had a EBTCM failure. I had a 1233 code which indicated that one of the wheel speed sensors was bad. It does not pin point the bad module. I checked every sensor, wiring harness plug and connector and all tested SAT!!! I broke down and took it to the dealer and they pin pointed it to a bad right front wheel speed sensor.
Reluctently, I changed the wheel hub/sensor and it did NOT resolve the problem. I didnt think that it would. Knowing that the EBTCM was most likely the problem and that my car was less than 30 days out of warranty and still with in the 36,000 miles, I called the GM custormer assistance center and asked them for assistance.

They told me to take the car into the dealer and let them fix it. They said that there was a VERY good chance that it would be covered!

After 3 days of troubleshooting, they determined that it was the EBTCM and the bill was $1600.

So I paid the man and it took me 6 months of FIGHTING with GM to get some sort of coverage!!! They gave me $1600 credit towards a new GM vehicle. I see that going towards my 07 Z06.

The EBTCM is a plug and play, and there is ZERO interface between brake fluid and electronics!! The module uses coils to activate hydraulic spool valves. It shouldnt take you more than 30 min to an hour to swap modules. No bleeding, programming or sweat!!! You do NOT need to disconnect the hydraulic brake lines to service the electronic portion of the module!!

I have pictures of the module and disassembled it to see waht went wrong! Looks like a five year old kid soldered the board! I found a dozen cold solder joints! I have yet to re-install the old repaired module to test it.

My recommendation would be to disconnect the plug from the module, read each wheel sensor at the plug, read all of the input voltages at the plug and see if you have everything that needs to be there to make the module work. If you read the wheel speed sensor with an ohm meter, you should see around 1150 ohms and if you set the meter to AC volts and read the wheel sensor as you spin the wheel,, you will see a small AC voltage that should increase the faster you spin the wheel.

A common failure problem with the EBTCM is the system ground. The ground wire is located on Chassis Ground lug G-101 which is located on the frame rail under the hood and will be just inboard of the area where the hood support attaches to the frame. It will be a single wire with an eyelet type ground.

I have pictures of everything and can provide you all of the inputs/outputs at the module plug if you want to do some investigating before you plop down money for the EBTCM.

Bill knows this better than most any of us....trust the experience. He's helped me chase this whole system down for the last couple of months.

I too succumbed to the dark side, took it in, was told to replace a hub. I did so and the problem still occured. I just ordered one and am waiting to get this little pos installed asap.

My two cents on this that I can add for reference is that the modules are different from 99-00 and 01 & up; There is also quite a price difference between the years. If you have the 99-00, the list price is $474.40; if you have an 01 & up, the list price is over $900.

I called around and the best price I found was from GMPartsdirect.com at $289.57 including shipping and handling. P/N for a '00 with "Active Brake Control" is 9376711.

Also note, that there are references to an "EBTCM" and an "EBCM" which are the same module but are used interchangeably in discussion. They simply may have called it one some years and the other later....

 

on a similar note i found a fellow members car to have an intermittent open in the signal wire to the ebtcm from the rf wheel sensor. sensor checked out fine but behind the engine in the harness it was open. all the sensors feed directly to the ebtcm no splices. so i just wound 2 new wires a million times around eachother, spliced them into the stock connector and took a deep breath as i cut the 2 feed wires on the ebtcm. runs fine no probs. yet another harness issue, prob from a battery that leaked. just waiting for the next one.

Do you know the p/n for a 2002?

 

DTC C1242H and C1214H for me. Comments?

 

There are a BUNCH of numbers on top of my 02 EBTCM. Here is what I have:

It is an ABS 5.3/TCS/MSVA2/DRP/AH, Model: 90390570/10323578

There are also two large letters on the top right side of the tag: SF and NK on the front.

750 is cheep. Stealer quoted me $1200.00 for mine.
