C5 ABS Issue after front end collision
So this C5 I'm rebuilding is getting close to being done.
I'm trying to figure out if the ABS system has a way to positively differentiate between the EBCM and say a sensor failure.
Up in the front right I have two wires that are clipped and appear to have nowhere to go. One is blue, one is black.
Any idea what those go to and if there's a way to check all the sensors before taking the time and $$ to send the EBCM out?
Thanks,

once you power up and drive the car, if there is a fault you will get a DTC that should tell you if the abcm or one of the wheel speed sensors is not working.
Two cut wires from where? the wheel speed sensor connections are large and gray, compared to the wires. If you have a connection to a wss, then follow the wire. if if goes into a bigger bundle of wires, then that is ok. The wires may be the ac clutch. then there’s the under hood light, and the ambient air temp sensor all on the right side

It's not the AC clutch because it works fine. Not the Ambient Air temp sensor, that works fine too. The under-hood light isn't hooked up at all, they put it back on and didn't connect the wire but the end of it is clipped completely. I haven't seen a connector that matches two wires.
It's in the same wire bundle area as the right fog light, right turn signal, and right front running lamp, all of which are there and work.
Just two random wires, and they're pretty long. It may very well be the under-hood light. I don't see a connector for it. Need to get it up on a rack anyway, just sits way too low to see anything under there really on the ground.
Thanks for the ideas.
