international t444 - I need help interpreting diagnostic codes
I just started to examine a temperamental 2000 international 4700 t444. (175 hp)
The check engine light is not on, but the truck has been running poorly so I decided to pull the flash codes. I am new to internationals so I have a few questions. 1. Does it look like the codes I pulled may just be old stored codes? 2. If so, how do I clear them 3. If not, but do you make of the codes I have pulled.
I dealership faxed me the "Electronic Control System Diagnostic Form EGED-185" which is what I have been using to interpret the flashes. Here is what I got
111 - NO errors detected
222 - Brake switch circuit fault
113 - Electrical system voltage out of range (low)
626 - Unexpected reset fault - ecm memory lost power
231 - ATA data Communications link error
525 - Injector driver circuit faulty -ECM can not supply sufficient voltage to injectors - Engine harness, injector harness, or ECM problem
I suspect that some of these codes are old and were never cleared. I know the truck recently had the alternator go which would explain 113, 626, and maybe some of the other codes. What do you guys think. Also, if anyone knows where I can find an engine or complete shop manual for this truck I would be interested in viewing/buying one.
