Recent Body Control Module Flashes!

[Viper Specialty]

I am curious if anyone has had the most recent Body Control Module flashes? Originally, these flashes were developed to deal with the flickering headlight issues in 03, however, I am curious to see if the most recent ones contain a fix for the "too fast window roll-up" problem in the 03-04 cars where the window would raise early into the outer groove, or didnt always let the door close. According to the info I recieved today, that are all the way up to AL in the flashes! For anyone not familiar with Dodge prefix system, that means they have changed the damn thing TWELVE times! My 04 appears to be running on an AI flash, and still has the "quick raise" windows.

The 2005-2006 cars use a body control module that has different timing (it waits a full 1-2 seconds after door is closed to raise window) Unfortunately, this new controller will not work in 03-04 because Dodge in their infinite wisdom decided it would be a good idea to switch some of the wiring around. No... not actually change anything, just swap a few pins around to screw with us. Thanks Dodge

Daniel, thanks for the info. I'm bringing my car in for the 22,500 mile service soon and I'll ask about this. I'm not sure if a longer delay will fix my problem. It's the amount of drop, not the delay. At least on my car.

Not sure if I understand... so that means we could in fact get the reflash? or we could, if they swap a few wires? or we can't?

This sounds like a great solution! I've had many conversations about this issue. That is an easy solution! Just delay the "up motion"!

Could we, add a time delay chip directly to the wiring?

The amount of drop is the same on all cars, but if THATS your problem, I suspect that your window goes too high to begin with. Just have them lower the window stop a little, and the lowering point will lower along with it. It uses a hall effect sensor to move it a given distance away from the stop point, not a given distace from the bottom.

However, it would be interesting to see if these new flashed do include something along these lines of a fix.

I thought there may be some confusion over this post...


This post is not a statement, but rather a question as to if these new flashes do include a new, longer window delay.

It appears that Dodge, for the 05/06 cars moved some wiring around on the body connectors- for no apparant reason. The new 05/06 BCM appears to contain all the exact same inputs as the 03/04, with the exception of the Export stuff that our USA cars wouldnt have anyway. However, Dodge aranged all of the pins differently in the connectors as to eliminate 1 of the 5 connectors, so our 03/04 connectors will not function correctly pluged into an 05/06 BCM. Now, Is is possble to take all of the connectors apart and rearrange the harness to work with an 05/06 BCM? I would have to say yes, but it wouldnt be easy. You would be dealing with 4-5 34 pin connectors. Another problem is that BCM's are VIN stamped electronically, and you have to give them your VIN to order one. Unless you know someone at Dodge that would let an 05 BCM slide through with an 03/04 VIN, you would have to put another car's VIN in it.

The BCM swap is a MUCH more difficult task than just flashing the BCM for a delay, when the only reason Dodge appears to have made the swap was to save 5 bucks on a connector.

If someone with an 03/04 gets the flash, please let us know if your window timing changes. Just go in and complain about flickering headlights, and they will do it automatically.


Worst case, perhaps if we can get enough people together to confront Dodge with the problem, they will write a fix for it? Obviously they know about it if they remedied it in 2005- but the threat of hundreds of SRT's flooding the dealerships for the same issue could light a fire under their A$$ if they have already addressed it.

Daniel another related issue seems to be the way the door sensor operates. If the door is closed just enough to trigger the sensor but not enough to fully latch, the glass will be in its raised position so a reattempt to shut the door without manually lowering the subject window first will cause the glass to be outside the window track – not good. I don't know that a flash or module change will fix this situation anyway. So as it is now, best just always shut the door firmly so it latches completely the first time to limit this annoyance.

SnakeEye- I have never seen this issue, perhaps you are running a very old firmware? In my 04, if the door does not fully close, the window comes back down to its lower level, it does not stay up. A flash could certainly fix something like this, as if the sensor shows the door back open before the extra delay times out, it would never raise the window in the first place. The door assemblies of the 03-06 cars are all identical.

I will look into it then. Thanks.
