Lost use of wipers, cruise etc. According to a Lazyday Tech, the chassis multiplex Control module needs to be replaced but we can’t find a part number. Any help would be appreciated. Thank You.
Also, there isn’t a separate smart wheel control module on this coach.

Gary,
The Smart Wheel controller should be mounted in or very near the driver console on the left side of the driver seat. The diagrams for it are in the 2008-2009 Marquis wiring diagrams in Coach Assist. See pages 157 for location note and 151 for wiring to the controller. A note on pg 157 indicates the controller is should be mounted inside the coach. This is different from earlier models where it was mounted in the front electrical bay. Suggest you get the tech to verify that signals are coming from the Smart Wheel to the controller. If not it could be a bad clock spring in the wheel.

Gary,
the chassis control module you are referring to is a Kongsberg Multiplex CCM. Unfortunately they are unavailable. Do a search on any Monaco forum and there are a number of opinions on a solution, none of them any good. Hopefully as Steve said, it’s just a clock spring. Hope this helps, good luck.

Hi Gary,
Just ordered a replacement module online at Northwest RV Supply (nwrvsupply.com).
They are pretty proud of these modules. Mine was just south of $290.
My model is on back order, due on 02/24.

Do you have the part number for the replacement?
-
Gary,
The diagram on pg 157 that I previously referred you to shows the following:
VIP Control Module Series II
SM-211 Rev B D10331B
Software Rev. 1.0
I would not order one until I had the one in your coach in hand to verify I was ordering the correct part.

Bob,
your 2006 Marquis does not have a Kongsberg chassis control system. They were installed on 2008/2009 Monaco motorhomes. Your multiplex system is an Intellitec house control system, completely different than the chassis multiplex system. On the Kongsberg control system, there is a +5volt power supply issue that controls the Smartwheel functions, with a few workarounds, that are discussed on other Monaco forums. The actual module is obsolete, a few have been found in motor home salvage yards, but are very pricey$$$$. Anyone that owns a 2008/9 Beaver Marquis, I highly recommend you research this problem, as there are very few options to address the problem. Hope this helps.

Frank, Not sure what you’re referring to. My post was talking about replacement of the control module for my SmartWheel. I wasn’t talking about my multiplex system or anything else. Did I miss something?
-
Gary, the replacement is Model #SM210. Northwest RV supply described this as an upgrade replacement for the coaches original SM209. There are several different models listed on the website. The model is on the face of your module.

Bob,
As Gary stated in his first post, there is no Smart Wheel control module on the coach. Those functions are performed by the Kongsberg Chassis Control Module. It is a different setup than the one on your coach. These systems are discussed on Bill D’s Monacoers forum for anyone that wants to research the Kongsberg CCM. Hope this helps.

If the tech could not find the module how did he manage to check the related wiring IE the clock spring and switches .
I wou!d take Steve's advice and first locate the module and then using the wiring diagram pin out the wires for the wheel checking the switches and wiring back to the module also check for power and grounds.
Seeing as that the only moving parts in the system are the switch and clock spring, and the clock spring is a common failure I would suspect that over the module.
As I used to teach my apprentices automotive computers and modules don't die there murdered meaning seldom does the module just stop working it's usually an out side force which spells it's demise such as a voltage spike ,reverse polarity or a short / over current condition .
Assuming that no one has inadvertently tested the module incorrectly / to death. The problem will usually lie in a wiring issue such as switch or wire connection.
In the case of the steering wheel controls the clock spring which consists of a ribbon of millar plastic material which a printed circuit is applied and then coiled into a plastic case , the ribbon coils and uncoils each time you turn the steering wheel this action eventually cracks the millar breaking the circuit.
The connections to the clock spring at the lower end of the steering column have been known to get hit and pull apart as well
As I said earlier I would find the module and do my own testing before condemning the module .
It very well may be the module but if it is you need to know what killed it before installing the new one in.
Unfortunately some of the murders escape undetected
In dry climates static electricity introduced by the driver through the meet touch of a switch is sometimes enough to take of a module or curupt it's programing.
Hope this helps

Gary,
I was mistaken. The diagrams for the Smart Wheel Controller I referred to earlier do not include the 08-09 Marquis. We also have a set of diagrams for the 08-09 Marquis with Kongsberg but unfortunately they do not appear to show the actual Kongsberg wiring (at least I was unable to locate it).
If any 08 09 Marquis owners have a set of wring diagrams showing the actual Kongsberg PLEASE contact me so we can get a copy on the Forum.

Gary,
Page 170 of the Marquis 08-09 w/Kongsberg diagrams shows the layout of the front and rear CCM modules. No part# is listed on the dwg but an iRV2 post indicates the Monaco # as 16623981. The Megatech # E0200B01. Apparently Kongsberg used the Megatech module. The layout of the front module shows a wiper fuse but nothing regarding the other smart wheel functions.
Since the module is no longer manufactured and will probably be very pricey if you do locate a used one, I would double check the connectors coming from the smart wheel (should be in the steering column).

Gary,
Not sure which model you have, my experience with VIP smartwheels is usually the "clock spring" Eventually they leave carbon tracks where the 2 spring loaded carbon brushes rub the contact internal track. Yours is the spring loaded type that comes pre-wound with a taped seal to secure it in location while you are installing it. Give VIP a call for help. If the tape came loose, re-wind 1 3/4 turns and tape it before installation. Good luck, Fred

Gary,
Attached are two wiring diagrams that show the VIP Smart Wheel connections for the CCM. Also, attached is an image of the CCM with connectors J1 and J8 called-out. It appears that the Smart Wheel is connected via J1, pins 24 & 25 and the windshield wiper motor is connected via J1 pin 19 and J8 pins G & H.
X2 on what Frank said, there is a lot of information on the Monacoers and IRV2 forums related to the CCM, some specific to the Smart Wheel issue that you are experiencing.

I added the Wiper and C Control diagrams to the 2008-09 Patriot and Marquis w/ Kongsberg wiring diagram sets.
Thx Scott!

Our 2008 Beaver Marquis has been having intermittent issues with all Smart wheel functions. Often upon start up and maybe the first hour all functions work normally and then nothing, no wipers, cruise control quits, the cruise light stays on but not operational, then maybe an hour later all works for a short while. Basically hit or miss. We have the Kongsberg CCM, and had the coach in the shop to check and or replace the clock spring if needed. The shop bypassed the clock spring and still had an issue. Had to leave the shop with no repair, but the tech felt it could be the 5V supply, and thought maybe it could be the power supply heats up during operation and provide low voltage. On the Monacoers site I found some great info about installing a separate 5V power supply. I located wires 26 and 27 on J1 and checked they read 5V and then tried again a bit later and had only 3.97 V. So I chose to try a new power supply. The improvement was cutting wires 26 and 27 on J1 and inserting a 5V power supply ($15 on Amazon), and all looks steady at 5V now. Hope this is the long term fix.
