2007 International 3200 dt466 Starcraft wiring diagram

Desperately need a wiring diagram for this bus. Batteries got stolen (cut the cables) and now it will not start after replacing them.

Uhhh... no offense, but I think wiring might not be the main issue here. Maybe call a tow truck and figure out the wiring later?

Edit: my response sounds snarky, but I just meant to point out that getting it started isn't going to help much. I don't see any way you're driving that bus out under it's own power, and trying will likely make matters worse.

What are the symptoms?
Check Engine light?
Error codes?
No dash power?
New battery voltage?
Do you have a multimeter?

Are you sure only batteries were taken?

Did you also replace the cut wires that go to the ecu and tcm ?

If the engine computer does not have power, bus will not even crank!

I saw that bus on the news a couple of months ago.....

The TCM gets it's power directly from the batteries so look for a couple 10 gauge wires, red and black and get them hooked back up. It won't do anything because the start circuit goes through the TCM first. Also the tranny won't work w/o power either. I think you just need to look for those wires, good luck.

I'm with the gang here. I opened this thread to say exactly the same thing. You have one or two sets of small(er) wires directly connected to one of your batteries to supply power to the ECM. Without them it will not start.

davsonlyn · 07-30-2022, 03:33 PM

Had to climb under bus to release the air brakes manually, in order to winch bus onto solid ground. Hooked up wires as advised one red wire with inline fuse says tcm feed on it. When trying to start at the ignition switch lights come on as normal. Goes thru its flashing dash lights and stops with just the brake light and seat belt light illuminated but no Wait To Start light on like usual. Try to turn over with key and get just a click from the fuse box on dash passenger side ignition relay. Can jumper starter at starter relay under hood but doesn't start up.

I believe (not positive) that TCM is the transmission control module so that wire was power to that module.
Was there another (you said hooked up wires) that wasn't labeled but had an inline fuse? That would be the ECM or engine control module. Without ECM power there will be no fuel. Not sure about engine turnover as when my batteries are low it can still turn over.
However there are minimum crank speed and minimum battery voltage requirements before you will get fuel.
My bus is a 1996 though so some things may have changed.

If you didn't connect TWO smaller (compared to battery cables) gauge wires with inline fuses then you may be missing ECM power.

Can you pull flash codes?

davsonlyn · 07-31-2022, 10:34 AM

I have 3 red wires with inline fuses and 2 white wires. One of the red wires says ENG ECM FEED FUSE. I have 17 fault codes 1: 2 612_ 14P, 5:240 639_14A, 4: 1 612_ 14P, 5: 240 639_14A, 5: 1 611_ 14P, 3: 1 612_ 14P, 4: 240 639_ 14A, 74: 254 639_ 14A, 228: 254 639_ 14A, 241: 254 639_ 14A, 14: 2 2033 14P, 255: 254 639_ 14A, 1: 240 639_ 14P, 1: 2 613_ 14P, 1: 4 613_ 14P, 110: 5 2023_ 14P, 150: 2 2023 14A, 108: 5 2023_ 14P.

HamSkoolie · 07-31-2022, 06:44 PM

I'm no expert but it looks like you have high "counts" (how many times the fault occurred). Have you cleared the codes and then attempted to start?

davsonlyn · 08-01-2022, 01:34 AM

No, I haven't cleared the codes. I will try that. I wasn't aware that would prevent it from starting. I don't understand the format of the codes. Is there a way to check the ECM without replacing it? I'm thinking it might have something to do with not turning the starter over from the ignition switch and no wts light coming on. That's where the schematic would help a lot.

It won't prevent start but it will get rid of old codes and show you what you have right now.
Then the troubleshooting begins.
How did you pull the codes since those weren't flash codes....to detailed

Yes, please explain, How did you pull these codes?

Since you are pulling codes, that would indicate the Engine ECU has power and is communicating, which is a good thing.

What tranny do you have?
An MD tranny, if the tranny TCU does not power up, then the bus will not even crank.

davsonlyn · 08-08-2022, 01:58 AM

These are the codes I'm left with after clearing
5:240
639_ 14A

74:254
639_ 14A

228:254
639_ 14A

150: 2
2023_ 14A

4:240
639_ 14A

241:254
639_ 14A

255:254
639_ 14A

davsonlyn · 08-08-2022, 02:04 AM

I just pushed the coast on and resume buttons on the steering wheel at the same time. I've never pulled them in the other format. I have an Eaton tranny will check the model asap.

I myself have been trying to figure out how to decipher those codes you listed.
From what I can read on the S08327 Service Manual dated 2009, well it just don't make sense to me.
I attached the manual for others to view and maybe chime in.

2009 will be different as the codes come up in J1939 PGN format.. his codes should still be J1708 style... they are different than the old flash-codes that the Gen-1 ECM's give out..

No wonder…learned something new!

Let’s see if I can find the right DTC codes….
