I just recently had to have the BCM replaced due to moisture. I had no problems before the BCM went bad. Now after the mechanic replaced it my idiot lights for the ABS, Trac off, and check engine lights are on. The anti lock brakes and traction control aren't working at all. I contacted the mechanic who replaced the BCM and he says there is an engine sensor causing this. Is there such a sensor or is it related to the replacement of the BCM?

It would be a huge help if you can post the codes that are stored in the engine control module and the ABS Module.
