Has anybody replaced the BCM and have success? I looked around the site and as usual found a lot on the ABS Sensors/Harness/Lights but here's where I'm at:

I changed the driver side wire harness, because the traction control seemed to activate more on right turns. Didn't help.
I then tested the Ohms of both wire harness's on the car (one new, one old) both were identical. Tested both ABS sensors as well as a new one at AutoZone, all 3 tested the same. So it would appear they are fine. The issue has gotten worse. To the point now where I'll hear the groaning and grinding even when I'm not on the brake. Recently, the ABS/Traction Off/SERVICE TRACTION lights will all chime on within 2 minutes of having the car on and moving and completely cut the system off ( so it drives/brakes normal).

The reason why I'm thinking BCM, my fog lights have never worked since I bought the car (checked bulbs, switch, relay, and wires), driver heated seat randomly stopped working, used to have a ton of trouble with starting the car/gauges going crazy thanks to a loose wire going to the BCM.

Just looking to see if this makes sense to someone else before I go ahead and buy one,, and spend more money than I'd like on this damn car that's been nothing but cursed since the day I got it.

 

Did you do any checking of the rear hubs? They can also trip the ABS/Trac system

 

Doing that tomorrow. I didn't before since at the time it seemed to only happen when I was turning. Checked for rear sensors at AutoZone the other day and according to that, the car doesn't have them lol

 

I have the same exact issue. So annoying, would love to find a fix!

 

It could also be the ground wire on the bottom of the abs unit. It comes out of the lower left hand side and runs to the drivers side fender well, mine was busted in the middle of the ground wire causing me issues. You couldn't see the break, but when you wiggled the wire around it would fix the problem. Worth at least taking a look at before you spend a whole bunch of money, also it threw a code, so if you can get the codes read it may assist you.

 

I'll have to check the ground. No code's are being thrown now (The ABS/Traction lights come on and shut the system off almost immediately now) but I had a ton of problems with the BCM and a loose connector a few years ago. Affected the Voltage gauge, security/anti theft system, radio, and wouldn't start sometimes.
