AlfaOBD

Exactly what does the system change in a circuit when you select a light as LED?

Turns off the pwm feature. I can't remember exactly what it is, something like pulse wave modulation. Essentially if you ever watch videos of people recording led lights you'll see it looks like they are either flickering or a rolling wave to them. That eliminates it which I believe causes the error messages when installing led's. The computer isn't seeing a steady current

I see, thanks. I have Morimoto fogs and nothing indicated a resistor is needed and I'm wondering if I set these in AlfaOBD to LED if it would be optimal or not.

Can't hurt anything.

The resistors were only required on 15+ trucks, something changed in the BCM coding on those models. You should be good to go.

I have the same fogs and saw no reason to change to LED's in Alpha. This is a 2014

Download the app that came with the mx and you can update through that

4.3.8 up to date. All good

Watch these videos.....setting them to LED is beneficial to eliminate PWM

Apparently the 2014 1500 can handle the morimoto's without issue. I think something changed in 2015

Yeah, It's pretty well known that the bulb-out detection system got a lot pickier with the 2015 RAMs. There's also been some observations that the higher end 7" EVICs (which apparently run the bulb-out system, or at least interpret the BCM's running of it) on all the years are pickier than the 3" EVICs.

Yes the premium clusters are more apt to display a light out message then the basic cluster. When I installed switchbacks I only changed turn signal to led's and was fine with the basic cluster. When I installed the premium cluster only when the lights were on I would get a light out message for the parking light. Switched that to led and have been fine since.

2015 model year is horrible for led's. Some companies will list their product as not compatible with 2015. Even changing the settings in alphaobd might not be enough for 2015.

I just wanted to say “Thanks” to everyone. Several people sent me their BCM config and it is helping me sort everything out.

I've managed to get rid of all the faults and got almost everything working right down to the rear sliding window we put in. So most of the BCM changes have been cleaned up, I don't see the "ecuConfig5" for the heated seats though which gives me a small problem I still have to overcome. However the truck won't start as I think the intrusion prevention system is unhappy due to the BCM:

I tried to change the VIN in the BCM, but Alfa is giving me back an error that says the sequence is out of range.
I also couldn't change the "VIN's must match" (Not the correct wording) setting in the RF Hub either, it too throws an error and cannot proceed. So I think with the BCM change and not being able to switch these two settings is the likely cause of the truck not starting. So we'll have to get it flashed... which is the safest thing to do anyway. We'll see then if I have to use a 2015 BCM (or perhaps newer) rather than using the 2014 BCM in a 2015 truck.

GordDavey,

When you get time, can you share any and all information on getting rear sliding window working?

I have added one 2 years ago, and did with factory switch and relays, would be nice to do all factory if possible.

Thanks you

What happens if you try to reset the RF Hub using your original PIN for you truck?
Also, did you perform the “clear multi-module VIN handshake Immobilizer failure”? I’m assuming that’s what you were referring to above?

I have also installed the factory power sliding window. There are no modules or relays besides the switch itself. It's a simple five wire system. Ignition on run power,ground,illumination.window + and window -. The switch itself is a reverse polarity. Push it one way it's + - push it the other way it's - +.

I have been going through this thread, and there appears to be a change and people have been having an issue programming keys. Anyone resolve this issue yet? I do have an email into AlfaODB.

Rick's Ram,
Do you have part number on harness, parts Dept was no help.
I ran thru relays cause I was afraid of burning up switch. Used ign hot to power relays, and fused battery to feed window.
Old school style

Thanks for the reply

The harness is incorporated into the headliner. That is why the dealer cannot give you a part number. I made my own harness. This is a picture of the schematics. It's honestly this simple. When the switch is not being pushed one way or the other no electrical connection is being made. It is a momentary switch. If you have the pigtail connector for the window switch it makes it much easier because we have not been able to find that particular connector. The actual pin# are on the switch itself if you don't have the original connector. I tapped into the overhead console light for my illumination. If you don't have the overhead console you would need to find another source if you wanted the switch to illuminate with your headlights.

I am having new problems connecting to door modules since the upgrade. I want to blame it on the MX+ but maybe it is not.

 

[WVRam68]

Ok, the plugs is what I really hoping for. I found micro stak-ons for speakers and used those to tap into switch and motor.

Maybe I'll get lucky one day and find a harness in a salvage yard.

Thanks for the info, and all your assistance to everyone on the upgrades you've done.
