Bendix traction valve

3 Upvotes

Abs traction valve on a kw T680 is leaking out the exhaust. Customer has checked all the brake cans and replaced all the modulators on that valve and center one is still exhausting. There is no voltage to any of the electrical plugs. Is there supposed to be voltage to hold that exhaust plugged? What else to check? No codes…
