Check engine codes

[Waterloo]

Could be a canbus issue, you need to get a diagnostic computer on it to trace the fault code. If the ABS light is going off, that normally entails getting into the cab or body controller, you will need a copy of Diamond Logic and an Inline 6 reader or take it too an International dealer and have them diagnose. Or, Love's and International have teamed up, I would think Love's would have the Diamond Logic software and should be able to discover the issue, or at least get you pointed in the right direction.

On my ProStar, I had the ABS, Jake, TC and another idiot light going off. Turns out it was the compass module that was bad. Yes, the compass, N, S, E, W. I replaced that, $20 off of eBay vs $400 at the dealership, fixed the problem.

Bottom line, diagnostic software may be the best way to chase this issue down.
