Mystery air valve ? - Yauchout - 11-02-2024
Does anyone have any idea with this? Air valve is behind the battery box on my international Lonestar it is leaking right where that screw is in the picture looks a bit like an adjustment screw. I would like to replace this valve but I have no idea what it is

It almost looks like some sort of abs module like the ones you'd see for steer axle brakes on each side? Maybe for a similar purpose?

My truck does have the Bendix ABS ESP roll stability system but that valve isn't listed anywhere in any of the diagrams I can find and it doesn't look anything like any of the other 6 ABS valves on the truck

I thought I would update this. It appears to be the at-3 traction control valve. It looks like they updated the solenoid at some point and it's square now instead of round
