If you unplug the PSM (Parametizable Special Module) under the driver's seat you won't get any alarms or lights. It is what controls the electric step. Once a driver breaks one of these ridiculous things we remove it and then unplug the module. We ain't spending $1000 for a new one...

I used a paper clip. Cut it down to size, bent to fit in the holes. A short piece of wire would work as well. I'd probably strip the ends, then use solder to stiffen them up to push into the holes in the connector.

Either way, wrap the whole thing securely in electric tape and tuck the connector up out of the way and the weather.

Default Re: Removing the electric step

I have the factory electric step on my 2016 3500. It has a mere 6000 miles on it and has never seen gravel or mud... but i have to wind up and slam the sliding door extremely hard for the step to close. WTF?!
The local MB service department says I would need to find out which up fitter put the step on and go to them to have it removed. (WTF?!) But, they also said that they can go into the vehicle's computer system and remove the code which would disable the step as if there was no step, and that it would take less than an hour. Does that sound right (or wrong) to anyone? I think I'd cough up the $150 for the hour if it was that easy and then pull the damn thing out myself because I'm thinking the step will only be a headache going forward even it was "fixed." I like the look of nerf bars/rocker bars any way.

Camillo,

Was it a factory fit step or added by an upfitter?

If factory fitted (ie included on your build sheet or data card) then they should fix it for free under your warranty.

Hi, any tips on how to remove or unplug the PSM it’s pretty tight in there

Thanks!

in your write up I could not find what hole or “holes” you put the jumper in. Your explanation of each wire has been really helpful but I am not sure hole on the connector the jumper goes in.

I am also consider removing the PSM like some others have suggest but I cant figure out how to unplug it. I am also worried that it controls more than just the step and I would be messing more things up...

UPDATE

Using this threads helpful information I was able to to remove the step and get one of the alarms off by using the paper clip jumper solution.

Thanks!

I still have a dumb beeping every time we open the door for two minutes.

I figured out that if you put the key in and turn the key to the right, then back to the left and out, it stops.

Has Anybody else figured out a way?

Thanks for the help everyone:)

Default Re: Removing the electric step

I have also removed my OEM electric step and was presented with the buzzers and dash warnings.

I tried the 2 different jumpers suggested by ptheland and was not happy with either one (you either have to put up with the sliding door open buzzer or the dash lights and beeping...).

Next I unplugged my PSM. This also does not yield a complete result. The sliding door buzzer and the dash beeping are gone, but there is still a red warning about the step on the dash when you first turn on the van (image attached). But there is no beeping of any kind, and the red warning goes away after you start up the van and get on the road. I'm sticking with this "fix" for the time being as it is the least annoying.

I think the only way to shut this whole thing down may be to take it to the dealer to have the step deleted from the van's computer. Or maybe try to wire up ptheland's circuit with the relays to simulate the step.

Anyone have any other bright ideas?

BTW, the PSM is easy to unplug, once you pull it out of the rail that is holding it:

1. Pull the driver's seat all the way forward and lift the foam cover under there. Locate the PSM under the driver's seat. It's a black box slightly larger than a pack of cards and is on the first raised rail all the way to the left of the rail.

2. There are 2 tabs on either side of the PSM that you have to push away from you (if you are facing the back of the driver's seat). These are best released with a small screwdriver as the space is tight for getting your fingers in there.

3. Simultaneously push the 2 tabs and pull up on the PSM and it should pull straight up and out.

4. You can now more easily unplug it by pushing the locking tabs on the 2 connectors and pulling the connectors out.
