2000 ML430 code c1314
I have a code c1314 on a 2000 model ml430. I was able to gather some info that got me to the point where I was measuring voltage at connector two wires 23 and 46. The voltage reading I get is 2.6 volts. I checked power coming into the esp controller and have full battery voltage in but only 2.6 volts out for the abs hydraulic unit. I determined the controller to be bad. Replaced with used controller. Same code same problem. Same voltage reading. Replaced it with a third controller and got the same results. It is possible to have 3 bad controllers ? Or am I missing something else. Wish I could gather more info to point me in right direction. This in advance

Sorry for the confusion but I had to redo my login because I could not get it to work. I have checked continuity on all the wires from the abs module. No sign of any wires being rubbed or cut. I looked way up int that end of the harness also. Any advise is greatly appreciated.

I get a sporadic C1314, I consistently get the C1300 A7/3y6 front left solenoid hold pressure. I have not done the electrical check you completed, but that would be my next step, do you also get C1300? I haven’t ruled out the abs hydraulic unit but if my solenoid were bad wouldn't it fail all the time? I can engage anti lock repeatedly and have no issues, then just randomly be driving and get the C1300…I’m getting ready to euthanize the Mel but she’s been such a good truck, any thoughts?

ESP by default when "ON" should operate at 4 Volts. When the ESP switch is depressed to the "OFF" position it should be around 2 Volts and you should see the warning triangle along with ESP/BAS, ETC, ABS lights illuminate. Without a functioning ESP you won't have ABS. Did you test relay K6?
