XXS Electronic Monitoring Module

XXS Electronic Monitoring Module; this is a $325 option with no description of what it does...

anybody have any concrete idea of what this $325 part does, what is it's function?

This has baffled me as well. Query as to why no one that has ordered a 2500 up to this point has asked this question.

It appears to be an option on the 2500 but not the 3500 and only on trim levels below the Laramie. My local dealer is clueless. A search thru government-google resulted in;

2013 Ram 2500 buyers can specify the Electronic Monitoring Module and instrument-panel switch bank.

Selecting the 9 Amplified Speakers w/Subwoofer - $300 option excludes the [XXS] Electronic Monitoring Module option and vise versa.

And if you order the Ambulance Prep Group ($445) on a cab chassis model it will include the 220 Amp Alternator, Electronic Monitoring Module, Voltage Monitoring Auto Idle Up Sys.

So unless someone has something more definitive I think that about clears it up.

Maybe call RAM customer care and ask them? Had the same issue on our 2012's - turns out they came with a tracking module......

Called Ram. They tell me it's a dashboard computer display showing compass, temp, and other programmable "stuff." Sounds like the EVIC. I thought they all had the EVIC standard these days.

I just received this from a dealer; not that really helps.


"I looked up the Electronic Monitoring Module. It is located by the parking brake. It provides what they refer to as a "generous array of input/outputs. It is a secure gateway to the power net arecture of the electrical systems and data base network.""

Okay, that makes sense. It's a bus node gateway. I wonder if it does conversions for regular signals or is just a bus translator? Thanks!

Thanks...

I ordered mine without it since Ram didn't find it important enough to describe on build&price or to the dealer I ordered from.

Here's part of the info you need, I have trouble posting the pics from the document.

2013 Ram 2500/3500 VSIM Usage Instructions
05/16/2013
VSIM (VEHICLE SYSTEM INTERFACE MODULE) USAGE INSTRUCTIONS
Overview:
New for 2013 is a RAM Truck engineered upfitter module called the VSIM (Vehicle System Interface Module). Its sales
code is “XXS” and is standard with Ambulance Prep (sales code AH2), a “must have” option with PTO Prep (sales codes
LBN or LBV), and is available as a stand-alone option. It provides a multitude of useful I/O’s to increase upfitter
friendliness and upfit simplification.
Specifics:
1. Ghost drawings showing the module location within the dash panel.
2. The VSIM includes an upfitter wire harness kit (part number 68211680AA or 68211680AB) consisting of four
separate color coded harness bundles. Each individual color harness must only be plugged into its
corresponding VSIM connector cavity, see photos below showing harness color installations.
3. A photo of the four individual color coded VSIM upfitter harness bundles. Note that in a few instances an
individual wire color is duplicated within a bundle – these duplications are further identified with a paper “flag”
showing its circuit number. It’s recommended that the upfitter, upon harness bundle routing direction
determination(s), install additional harness bundle abrasion protection over each bundle (such as harness
convolute).
4. Photos showing module installation within a vehicle and harness bundles.
5. A chart below delineates the circuits within each color harness bundle, circuit number, signal, wire insulation
colors, maximum allowable amperage per circuit, and circuit function.
6. A chart below delineates the available 125 kbaud CAN bus messages. If downloadable “DBC” files are needed,
they should be requested via the website rambbg@chrysler.com.
7. Note 1: Eight “pairs” of “output” circuits may require additional circuitry for proper function. These are flagged
in the VSIM chart with an asterisk (*) in front of the Circuit # and yellow hi-lite in the box. If any these output
circuits are being used and unless both circuits of a given pair are connected to an external load (e.g. a LED,
incandescent bulb, upfitter module input, relay coil, etc.), an external resistor must be added to the one circuit
of the pair that is not being used for another purpose. This resistor should have a value between 80-100Ω, and
wattage of sufficient size to provide physical robustness. See below for the VSIM chart delineating the “pairs”
circuits that require an external resistor and the accompanying appropriate circuit diagram. These circuit
modifications pertain to early 2013 VSIM usage in both the 2500/3500 HD Pickups and 3500/4500/5500 Chassis
Cabs; and are NOT required for these vehicles built after 5/8/2013.
8. Note 2: six “output” circuits require “pull-up” resistors for proper function, if the circuit output is to be used.
These circuits are flagged in the VSIM chart with a pound sign (#) in front of the circuit number and light blue hilite
in the box. These circuits require a dedicated 1K-2.2KΩ, ≥0.5W resistor for each individual circuit. See below
for the VSIM chart delineating the circuits requiring a “pull-up” resistor and the accompanying appropriate
circuit diagram.
