I'll see what i can find. would those be "normal" OBD2 codes, or do i need something more "invasive" like Alpha?
I might contact the guy I bought this form and see if i can't swap it for the non-air suspension, but WITH PTO. PTO would never work, but that would be OK, too. I also wonder if...
OK. Removed the tazer - no dice.
Is there maybe an enable line (ground or high) to cause the vehicle to talk to the "soft keys") (as compared to the piano keys)? It doesn't look like it, based o the pinout Jimmy provided, but the truck also backlights the buttons, which looks to be...
Yes, plugging the originals back in results in things working. This one DOES have the "extra" button (trailer height adj?) that my truck doesnt support...
One thing i need to try is disabling the tazer aux switch settings and possibly removing the tazer....
Jimmy - might need your help. Or I might need someone with AlphaOBD in Iowa.
Plugged the new module in.
Backlights worked. Truck knew there was a problem with parking sensors when I unplugged it.
Buttons did NOT work (park sense, Tow/Haul, Traction).
Aux Buttons did nothing.
I did notice...
Thanks for the advice!! I may put a drop of glue and some black paint on the "unuseable" button, since it won't have any function, and can't be repurposed. we'll see.
I will try and document as I go on this one. Seems like there's been a lot of interest, but noone's taken it to the end...
This is the panel I ordered.
I suspect the "ALT Trailer Height" button will either throw a code, or just not do anything, since I don't have that option. If it causes issues, cutting traces on the PCB is easy enough.
What OBD interface do you use? I see a bunch that Alpha says do work...
AV8OR- We're a heck of a lot closer than we were.... or at least I am.
Jimmy seems to have a wealth of information we haven't had before. If we can get the switches ACTIVATED (i.e., they light up when you push a button, and they send voltages to the pins he called out above), then we...
...and using an arduino to look for some logic signal and then respond appropriately to drive a relay - well, that's a lot easier to program than it will be to use the logic analyzer or scope to see what all the different wires are doing at any given time. hopefully there's a pin assigned to...
so, i might need to get AlphaOBD. luckily, i still have a balance on the giftcard i got.
I had to buy 68376641 which also comes with trailer levelling. I don't have air suspension, so i suspect that switch won't do anything. the other option was 68376647 which has the right vehicle...
a bit late... I have the Tazer, have enabled "AUX SWITCHES" in the menu, and no "new" menus have shown up on the radio. I don't have the switch bank, though. I'm looking to buy one (moparparts is sold out), and then experiment a little. If the original functions all work, then it might be...
Here's a model number decoder for the switch panels. 68376640 is the one shown in the FCA docs (traction/tow-haul/front and rear parking and 6 aux switchs)
Given the 4th Gen setup and switch configuration, their response is actually interesting (I read it earlier, and just re-read it). Might have to watch the u-wrench-it type places for a rig with that panel.
I've seen a number of posts where it looks like they've enabled the buttons in the head unit, and then they work to turn signals at the back of the switch panel on and off. From there, it takes some custom wiring to take the button outputs through a homebrew harness off to a fuse panel...
almost forgot - I'll post some "complete" photos. I did find on my last build that i needed to scoot the main 30A breakers away from the wall about 1/16" of an inch. I also had to get rid of the "ram-styled" chamfer , just because of fit. I got all my aircraft breakers in now, and wire...
after most of a spool of PLA trying to get everything just right, i'm about to order a spool of black ABS to get it built. now that i've got antennas on, it's time to get power routed so i can get some radios installed.
here's what I'm working on.... should wedge in there well (might need to taper the back just a touch - the intent is to NOT cut up the rubber mat in the bottom).
main breaker for loads in the front (some switched, some always live)
breaker for the igniton switched tap - which drives a relay...
under the ramcharger phone pad in my console is a "cubby" - just a small recess. Anyone have ideas what that is really meant for?
At the moment, I'm trying to get the complete dimensions of it (tough to measure the back height, because it tapers down), and am planning on putting a 12V...
