I swapped out a 4-channel rear for another 4-channel rear with different gear ratio (old 2.73, new 3.42). I had to swap the backing plates and axle reluctor rings from the old to new. Now the ABS/TC doesn't work and the dash reads out that the ABS is inoperable, and the traction control is always off. I wouldn't care so much if it was just the TC, but I want ABS to work.

Is there something that I missed during the swap, or a quick fix in the ECM?

I just remembered that I turned on the key switch to put the transmission in neutral before I plugged in the harness. I'll bet that threw problem codes. Now that the sensors are plugged in will it reset automatically after a certain number of key cycles, or do I have to wipe out the problem codes to start over?

Should just reset itself.

I cleared the codes and it didn't help. I guess it's a legitimate problem that I have to fix.

Are you positive the car has traction control axle shafts? I know aftermarket doesnt have the availability to get the axle shafts. So if a person had changed them at some point and decided to give up t/c....that could be your problem so check the axleshafts or try to replace with your old ones and see if that fixes the problem.

I feel stupid. I accidently put the sway bar u-bolt over the wires and crushed them. Problem solved.

Ya, you said it, brother! I had some really slim connectors and tubing on hand already, so at least it didn't cost me.

haha im happy you figured it out! ive considered putting non abs axle shafts in my car just because its cheaper and i dont use traction control anyway haha
