Greetings all, I have found my password so I am back.
I have an '04 MOC SS (Red), now used for parts, and an '01 MOC SS (Black) that is my driver.
ABS and trax lights have started coming on sometimes when I start it. This is before I go anywhere. Doesn't seem to matter if wheel is straight or turned, rainy or dry, etc.
The lights either come on when I start it, or they don't come on at all. They never come on or go off when I am driving down the road.
Brought it to the shop. he says it's a bad ABS control module. I asked about wheel sensors, hubs, grounds, wires, wires leading to the sensors; he says it's not those, it's the control module (I have previously had some wiring replaced on this vehicle).
Given how/when the lights come on, does that seem likely?
And... does the '01 MOC SS take the same ABS module as the '04 MOC SS?
I ask that because I have a relatively new ('14) electronic brake control module in the red parts car. I happen to have that because I brought Red to the dealership to track down the ABS/trax light. Replaced hub, still no go. They told me it was module. If I remember right it was $1200 plus labor? Drove it off the lot and the light came on again. I turned around and handed them the keys back. It turned out to be sensor or wiring or something. Anyway, they didn't charge me for the module. (PS, I found another place to work on my car after that.)
So my next question is, how hard is it to remove the module from the '04, IF it would fit in the '01?
Thanks!

 

I have not done this job so I will defer to someone who has but Rockauto lists the same refurbished part number for both years. The EBCM is between the master cylinder and the strut tower underneath the cruise control module. It has a wiring harness coming out of the front.
Here is the procedure for removing it; it doesn't look to be that complicated. I don't recommend attempting it on your driver if you are not experienced with removing parts and harnesses. There are four screws holding it to the BPMV. I couldn't post the illustrations. Given that the refurbished part is over $300, I will be putting this on my list for Pick n Pull's next half price sale.

Thanks, Glen, I appreciate the help.
Anybody got an opinion on whether the EBCM is indeed the problem?
