I have a 97 Camry with the Bosch ABS controller. The ABS light came on, and I did the test with the jumper wire, and came up with code 12. I pulled the harness apart, and checked as well as cleaned both connection points with CRC lectromotive spray. Needless to say that it didn't fix the issue. I went to a local salvage yard, and got another unit. My question here is, can I just remove the electronic portion of the control unit from one and swap it out without changing the entire unit with the brake lines? I did take one apart in the yard to see what was inside, and it seems like it should be ok..

 

Toyota has no service info beyond replacing the controller as a unit thus on your own.

However well worth a try to replace just the electric side. Suggest making sure you keep any seals in place to keep out moisture.

 

How's the replacing greg, just curious with the procedure and result.

 

I was able to swap out the electrical part of the ABS controller without any issues. The code from that, #12 did go away, but then I got a code #39 from the LR sensor. I will post a picture of the unit taken apart later.
