Hey all - first of all, this was not written with AI, these words are my genuine, human derived words from a flawed thought process.
My latest project is on a 2012 3500 Mega. I found some 2019+ powered running boards (OEM-RAM) from a mega and they fit. Mechanically there are no issues, they bolt right up. One thing that was odd with this pair was that they were identical, meaning not a left and right. Depending on where I locate the controller, I may swap them to save me some wire. I have no problems building a custom harness (it's only time and money).
So here are my issues:
I don't have a PSSM #68367399ae (2019+) - and there isn't a PSSM for a 2012. At least not that I can find - please correct me if I'm wrong ( I need YOU!).
I can buy the PSSM but that's not the totality of the solution. FWIW, I don't care if I can control all this with UConnect through the radio etc. I literally just need them to deploy and retract when the doors open, and having an LED light option is a bonus. Here's why I think I need the CAN for that - the PSSM has no idea what door or what side has an open door, hence the CAN sends a signal onto pin 7 or 8 (of the PSSM), to say that one of the driver's side doors is open or if one of the passenger side doors is open. In my old Ram, I had trigger wires that simply went to ground when one of the doors was open. There were four trigger wires that were spliced into two and those two went to the controller (drivers or passenger) that told the controller if there was a door open on a particular side and therefore needed to deploy or retract the step).
First REAL question - what does the CAN output on connector C8 pins 1 and 2 when the doors are open or closed? Is it positive, negative or shunt/null/ground? I'm assuming of course that it's analog. Are those pins only activated when the truck is re-programmed to have a powered running board (meaning do I need the dealer or a programmer for certain in order for those pins to even be activated?)? Obviously the CAN gets a signal from the doors, what wires are those? I can intercept those wires and go directly to the PSSM if I know what signal is on those wires (Pos, Neg, shunt/ground/null), and this eliminates the need for dealer programming. I just need to know what those wires are (where I'll find them) and what signal they carry.
Second REAL question - The PSSM outputs 5 connections (wires) to each motor and the motor wiring has 5 conductors. The PSSM is pretty smart, it senses if it can't deploy and it also senses if it can't retract, it then reverses power to the motor for like 3-5 attempts and then cuts the power to the motor if these conditions exist to prevent damage to hardware and electronics. My question is this, can I make them dumb? Meaning... that I'd like to introduce deployment power for 4-5 seconds and retraction power for 4-5 seconds. If there's something in the way then that's going to be an insurance claim . OK here's my thought process.... If I supply 12V on Pin 1 of the motor it should deploy, If I supply 12V on Pin 3 of the motor it should retract. Pins 4, 5 & 6 (of the motors) are for sensing and don't affect deployment or retraction unless there is an issue (over amperage detected in the PSSM) with the motor or a step obstruction.
Third REAL question - I really don't want buy a PSSM (sometimes I'm a cheap #$%^). I have an AMP Research controller that is capable of sensing when a door is open and is capable of supplying 12V to the appropriate motor (assuming I wired it to right side). It is also capable of giving me power for LED lights on the side or sides that the running board is deployed. AMP running board motors run on 2 wires (not 5), one for deploy and one for retract. Intercepting the "door open" signal prior to the CAN might be able to go directly to the AMP controller (maybe need to build a polarity switch or ground detect circuit).
I've scoured the internet, used AI to scour the internet and I still don't have the answers I need. Calling Dodge is like extracting my eye with a spoon, calling AMP is like stabbing it with a fork prior to extraction. I don't suppose that anyone has done this but getting answers to my questions will ultimately help others - we are all solving the energy crisis one gallon at a time!
How can you help!?:
