As I understand it. You can have ddec, and atec, read underlying situations. I would like to change the underlying situations to Not include any doors open, or no brake pressure, or handicap interlock. I am on the East coast, who is a good source to make these changes.
I have some experience with DDEC programming, about none with the Allison side. On the DDEC programming those things you mentioned are usually not monitored by the ECM. They prevent the engine from starting using starter and/or ignition interlocks. Those interlocks, if set will not allow battery voltage to ECM ignition wire and/or the starter solenoid.
Which DDEC level are you working with and do you have a chassis wiring diagram?

You mention ATEC controlled they can be programed with a few interlocks ,now if you have the WTEC they can be programed with about any type interlock, if you do have a ATEC Allison software is hard to find for it nowadays most Allison shops do not support it any longer but searching you may can find one

What transmission coding and software would be on a 2003 Allison B400R transmission? Thanks.
That is a World Transmission" WTEC" should be second or third generation electronics

Thank you, Clifford. That's helpful!
That is a good transmission the "B" stands for bus transmission FWIW
Sorry should have mentioned the 2000 model year mci d3 series 60 b500, and I assume ddec iv, with in the bay HC lift, kneeling, air lock bays. This thing is interlocked to death. The idle shutdown seems to be set for three miniutes, which is annoying.
I do not have the wiring diagram Yet, but have found alot of the diagrams for the sub systems , like the kneeling, and HC lift on MCIs web site.
So far I have found some will give throttle inhibit interlock, and some will give trans inhibit , and some both. Rite now I have a "door open" light on dash and both inhibits on. I found on an mci operators manual that says that is a bay door? they are all closed and all of the switches seem to be clicking, on my other mci they only work the bay lights, dont know if the switch is on the air side. I imagine there is a sensor on the bifold entry door also, Luckily the bus is parked on my lot. I would Hate to be stranded do to any of these numerous interlocks. Back to tracking the "door open" issue. Any Clues?
You need to find a Detroit Diesel Diagnostic Link CD for DDEC IV and interface cable. Hook it up to your PC, enter passcode and you are in. If your ECM is not set to a prior owners password, the default is 0000. Then you can make all the configuration changes you wish.

To add to Mark's post, you'll a Nexiq or Dearborn interface, $600 TO $800 dollars.
It's going to very difficult or next to impossible to fix without a wiring diagram. I'm guessing all of the interlocks are some type of limit switch that either completes or opens it's particularly circuit which allows the coach to function normally. If you are able to find a diagram I would take the approach of following the related circuit back as close as possible to the engine or transmission control unit and fake out the signal there. (that may not be easy as it sounds if the system includes redundant fail safes). That eliminates any future problem with the harness.
The idle shutdown timer is in the ECM program and a Detroit dealer or anyone with a hand held DDR or laptop with the Detroit software can remove the shutdown timer. As Mark suggested you should consider getting the software and interface for yourself.
Where are you located? PM me if you are interested in setting up your laptop with the appropriate software.
Ken
I'm sure with the Allison software you could turn off the related inputs and not worry about faking out the signal, I just haven't used the Allison software very much.
You can go into auto detect the MID 210 will come up as a bus chassis on the B500 and you can delete what ever interlock is tied to the transmission from there with a Pro/link
You are all talking greek to me. I do understand the basic protocols. I do want to change the programming to change the interlocks. I do not understand MID21o,,
I would be happy to pay someone to make these changes, but if I have to learn how to do it myself, I would appreciate some guidance.
Should I buy a Prolink?
I am in Delaware. I know if I turn off the appropriate software interlocks I wont have to worry about the associated wiring.
You own a DDEC engine with WTEC controlled transmission you might as well get your feet wet and go for a Pro/Link with the software on both you will enjoy it that's about all the dealers have

Yes, it is out of a Gillig 29 foot low-floor. Apparently, some Fed grant wouldn't cover the cost to replace that bus unless they did it now (and it could only be replaced with a 40-footer) so they dumped it. 8.3 liter Cummins (overhauled two years ago) and B400R (overhauled 16 months ago, approx 6 months left on warranty); less than 280K miles on the bus, 2003 model.
I'm really happy with it.
B-400R in my bus as well. Very good transmission. We have over 50 of them at work. They give great service and are much more reasonable to rebuild than the ZF.
