Hello,
I have a 2009 IC CE300 that has a malfunctioning "leave no student behind" system.
The system will not reset itself and "clear out" after running the route. The door handle can be raised several times, but to no avail....it continues beeping and goes to the honking/lights flashing mode.
Any ideas? |

I don't know if you checked, but the key needs to be in the Accessory position.
There are directions on the headerboard above the driver. I hate the systems on the IC's the most. |

| I had an 08 do the same thing about 2 months after purchase and what i found was one of the diodes they use in the system that are located in between the glove box (beside driver) and the top of the electrical panel had a wire pulled out of it (typical IC stretched tight wiring) if i remember correctly there are three of them in the same area, also they will fit or hang in panel area with a little wiring rearranging then they are easier to keep track of. may not be your problem but worth a look. |

| All of the issues we have had so far is the driver failing to set the parking brake. Fortunately, they were on level ground and didn't roll into anything. |
If it doesn't fit, FORCE it.
If it breaks, well, it needed replacing anyway.

Had one with interminted problem with rear switch ground, ran new ground wire to switch and problem solved.
Ground for switch is somewhere in the end cap. |

| Yes, parking brake is set (air brakes) and key is in accessory position. All procedures for disarming the system have been followed. |

| most what I see here is the park brake switch is bad. when you set the park brake it should illuminate the light in the dash. if it is not on and the park brake is set, thats your giveaway. we have had the occasional diode and other problems but most of the time it is a failed park brake switch. All our buses are air brake. hopefully this helps. |

| If all else fails, disconnect the battery. It will reset the system. |

I did find the problem- it was the parking brake valve, like several mentioned.
Thanks for the help! |

It had already been to the dealer twice, for a total of 3 weeks, and they couldn't get it to malfunction, and didn't know the answer to it!!! Basically, the park light would come on appropriately for them.
Why is it they "straighten up" when they go to the shop? |

It's run by a computer. Why should you expect more?
Bill Gates must be involved somewhere.Gimme those old (dependable) mechanical systems anyday.

There are a lot more on your side than you think. The younger generation may prefer the new buses with the electronic engines, multiplexed wiring, and all the bells and whistles, but most of us long for the days of mechanical engines, all-steel construction, and solid, reliable buses. |

I wish they could bring all the comfort and options of today's buses, with the reliability of yesterday's buses.
I love the way our Visions ride, and the smoothness of the 6.7L engine.... I think the bus manufactures would be ahead of the game to get rid of the multiplexed bodies and go back to the old wiring systems. |

As I recall it was supposed to integrate the systems on the bus, and make it easier for mechanics to diagnose problems. I think the hidden idea behind them is to CREATE problems for the mechanics. 
Even the little Starcraft shuttle buses at work have a multiplexer. |

I totally agree. I love my old 12 valve cummins engines. They are solid, and they are simple. If its cold out, plug them in, or give them a small shot of ether. Either way, we still know how to get them started if its cold out.
One thing I remember the head mechanic telling me about my bus when I bought it years ago was that since it was all mechanical, it wouldn't shut off unless you pull the cable, or if it runs out of fuel. He was referring to the mechanical fuel shutoff. :P
He told me if an alternator fried out, you could just keep driving no problem. |

All the creature comforts and interlocks and safety systems make multiplexing a necessity. It was done in cars and trucks years ago because the wiring looms were getting just way too big. And it was been done reliably. If you want the buses wiring to go back to conventional means, then you must expect to lose some creature comforts and new safety mandates. Don't get me wrong...I think some buses do need to be simplified...but multiplexing should be (when done right) your friend.
Frankly, I'd take a multiplexed bus that tells me where to start looking for a problem over my '06 All American that is wired traditionally with pinched wires galore and relays up the wazoo. |

| I found out another reason why it also won't deactivate. You have to open the Emergency Door slightly for I would say about 3-6 steady seconds then close it. I've learned that they now have made the system to not disarm if somone pulls up on the handle and not opening it slightly. |

If you have to open the door, there is something wrong. |

No, can't be. There is no switch to show when the door opens, only when lever is pulled up. Besides, why would you need to open the door? You only need to show you are at the back of the bus in order to check for children sleeping/ hiding. |
