Wheel speed sensor wires

[SIUlero]

Actually, that might be...I don't have a manual to look at so I was only assuming they went to the PCM. I can't tell the color of the wires at the hub connector because of the dirt on them, and they're twisted pair wrapped tight all the way from there up into the main loom. I guess I'll have to cut the wrap and find the colors, then hope I can find all four of them going into either one of the modules, unless someone knows what terminals they go to on the connector...the BCM is right next to the PCM under the dash, right? I'd really like to get this problem solved so 4 out of the 5 lights on my dash will go away.

just because its putting out an ac voltage doesn't mean its good. test the resistance of the hub, hook one probe from your multimeter to one wire, and the other one to the other wire. if it is over 1.5 M ohms its probably going bad. give me until tomorow when i go to work i'll look up the wiring diagram and post the colors for you. if you can give me either the exact code number or what the code says that will help a lot. also the noise your hearing over bumps is more than likely the upper part of the struts, gm has a tsb out about them. i'll try to post that as well.

Not the BCM (Body Control Module), but the EBCM (Electronic Brake Control Module). I believe it's attached to the ABS pump.
