| Alarm will not cancel 9 times out of 10. Was told the ESC (body controller) needs to be replaced so we replaced it and still the alarm won't cancel. That was after replacing door switches, relays and the 2 solenoids on the outside electrical panel. What in the world else could it be!?!?!?!?!?!?!? |

| Maybe somehow not recognizing that parking brake is applied? Or not sensing key is in accessory position? |
Why yes, the ORIGinal CHARGER is a Fastback |

| @Fastback forgot to mention that I also replaced the ignition switch and the park brake switch. |

A few years ago one of my NCLB systems started out not canceling randomly for driver, never acting up in shop, I kept telling her it was operator error, lol... Eventually wouldn't cancel at all and proved me wrong!...
Ended up at that point finding a wire pulled out of one of the diodes above wiring raceway, The raceway that runs thru top of outside elec panel.. under glovebox on left dash... I figured maybe wire was pulling or shaking around before that and losing contact intermittently? NCLB system on that bus has never bothered since wire to diode was repaired.... if I remember there are three diodes laying ontop of raceway, almost easier to find if glovebox was removed...
I have seen those diodes located inside of that raceway on some of my busses too... as wiring for them comes thru it anyway... |

| I will check the raceway area for those diodes. Thanks!!! |

| Update: found the diodes, the connections seemed ok. I tested the 2 diodes to the back door switch and found one to be erratic with ohms reading. The other diode tested good, replaced the bad diode and sent it back on route. I asked the driver to report back to me only if the NCLB acted up again AND sure enough it acted up AGAIN 2 days later!!!! I'm gonna replace the other diode and see what happens. |

Probably dumb question but does bus do this to you in shop or just to driver? Only reason I ask is I have a few drivers that still struggle with the consept of how those systems reset.... and run to back door to push button or lift handle, or have a bus aide on the bus that lifts it to quickly.... Not giving system the delay it needs, from moment key hits accessory, to be able to reset...
I am almost sure you ruled out human error... Personally here I have had very little trouble with NCLB system on my IC's other than operator error... that was why when one or two did actually have a problem, I was eating crow for awhile!! lol... |

| Lol... yeah human error has been ruled out, it's been the same driver in that bus for the last 5 years. The problem started over a year ago and it continues. It'll work great for a few days or even a week sometimes and then BAM!!! it'll start acting up again just out of the blue. |

Figured you had ruled the ole human factor out.... If not the other diode having something to do with it, still almost sounds like bus has a bad connection or loose wire somewhere? being as intermitent as it sounds like problem is.. keep us posted and Good luck!! |

| Update: Seems that replacing all (3) the diodes instead of just the bad one fixed the problem. Driver reported to me that it hasn't had a problem in a week and a half. It's never worked that long since the problem began. Thanks for all the help !!! |
