Customer Question

I'm working on the abs on a 1999 t800 Kenworth Is it possibly for the module to not send power to 1 valve only?

It is possible that the ECU is faulty. However , it is more likely you have a corroded wire between the ECU and the valve . Have you tested the wires going to the valve with a load light ? Do you have the wiring diagram ? If not , I can help ! Can we start with the full vin number please ?

Hi again Andy #XKDDBOXOXJ954755 I've followed the wire from the valve to the firewall plug can't see any obvious damage to the cable also where is ecu located?

Hi there ! I'm back ! I have found some diagrams for Wabco ABS for that make , model and year of truck. I did not go by vin number because your vin did not work in my system for some reason . Would you like these diagrams anyway ?
