Having a bit of an issue at my newest location. It was a little rough driving in, not the best of terrain. Right as I pulled into the spot I was parking in my gas pedal went lame. It springs back up into position, but when I press it there's no resistance and no gas getting to the engine. Engine was still running fine. I didn't think to try and put it into any gears other than going from N to D and trying the pedal again with no luck. My first thought is that something has been shaken/knocked loose from the terrain.
It was dark and I decided to just setup camp and start looking again in the morning, since I'll be here for a while. I decided to see if it would crank today, and do some troubleshooting to see if any of the other gears would work. However, when I turn the key on and the panel goes through its motions, then I get the "Check Elec System" light. I try to turn the key to ignition, and all I hear is a loud click from the area that the fuse blocks are located (maybe between those and the dash somewhere).
I'm not a diesel mechanic, or even a regular mechanic, by any stretch. I've mostly worked on motorcycles and smaller 2-stroke engines, so I have some knowledge, but mostly just willingness to try things out. I'm fairly far away from mechanic shops, too, unfortunately. I have a motorcycle I can ride into town for parts, but as far as my abilities where the bus is right now they are limited to mostly hand tools.
In saying all that, does anyone have any suggestions for what to look at next? This is what I've done so far:
- Reseated fuses related to ECM, IDM, or ESC (but I'm not sure I've found them all)
- Visually inspected as many wires as I could trace under the hood and chassis for melting, corrosion, or being disconnected (again, probably haven't found them all yet)
The bus has been running and starting fine for weeks, it was only after the rough bouncing around that it suddenly failed like this. That's my thinking/hope is that something simply knocked loose, but I have no real idea where to start widdling down the cause. The error codes I get seem to indicate one central failure in the ESC; wherever that may be located I'm not sure.
- 2005 International IC CE200
- VT365 International Motor
- Allison 2000 Transmission E004501
Error codes and relevant text:
"Engine speed not communicated to the ESC"
"Cruise control enable, active, state and vehicle speed not communicated to the ESC"
"Wait to start lamp information not communicated to the ESC"
"Loss of data link from ESC to primary EGC (150) or secondary EGC (250) Loss of communication in excess of 10 seconds"
"Engine Controller not communicating with the primary EGC (150) or secondary EGC (250) Loss of communication in excess of 10 seconds"
Much appreciate any advice or tips!
