He is referring to the ABS module and the electric brake pump motors. Some have dual electric motors. They should be coming on with the IGN switch on. Check that they are getting power and ground and are coming on. If not check the fuses, relays and harness. If there is power and ground but not working it would be the pump itself. Run through the manual to check for your codes and there is more in depth testing covered. I have to run for an appointment but can follow up later on my next available log in.

Thanks for the update. If yours does not have the diagnostic switch it will have to be plugged in with a laptop or scan tool with the wabco software to pull the codes unfortunately. You will need an interface with a 9 pin connector , laptop, and wabco program. The interface is usually any where from 400 dollars and up and the wabco program should be free.

Ok i have to figure this out , so im going to invest in navistar software , but I am wondering if your looking at the correct model truck because mine does not have the 9 pin connector either it has the 6 pin . I purchased a toughbook and am trying to find the right cable will any 6 pin deutsch cable work . I also have the genisys scanner but don't currently have the heavy duty unlocked as are repair facility just specializes in passenger vehicles ,I'm going to assume the navistar software will be better than the genisys software
