Above is an old thread from someone on the CV forum doing a seat swap; there's mention of the MM OCS module in the thread and thought maybe the info might help you.

From what I gather after reading the thread is you'll need to find another MM same year as yours and take the OCS module from it since the part is discontinued.

[Marauder1212]

Correct and no place in the world had one of these at there parts departments

Ive had this air bag light on for over 10 years....if anyone has one please sell it to me lol....only other idea i had was to take it to a place that test and repair circuit boards and see if they can just fix mine......

[Mr. Man]

Is there a shop that can fix all this electric stuff?

Some information that may be useful.
Back story, I upgraded my '03 300A and added heated seats (with the seat pockets). Had to do some custom wiring from the door panel switches to the seats, but that's a different story.
To the point, there are at least two different types of OSS sensors.
The '03 300A has an air bladder under the seat cover. I don't recall if it is under the cushion or directly under the leather seat cover.
The air bladder then connects to the OCS.
The heated seats I used for donors did not have the bladder, the OCS works some different way.
I don't recall if they came from a '03 300B or a '04.
I also can't say whether the '03 300B or '04 without heated seats uses the same type of OCS as the '03 300A.
My guess is all '03 300B and '04 use the newer method.
So just FYI, if you have the type with a bladder, it is possible there could be a leak, kink, disconnected hose, or something about the bladder that is keeping your airbag light on instead of the OCS sensor itself.

Thank you for that info and yes mine is a 03 300A and yes mine is the air blatter kind...i ve been under the seat and dissconnected every plug and strayed with electronic cleaner and put a little die electric grease on every connector the seat...

Also did the same with the main rcm module under the center console guages...

My scanner when i run the data scan everything comes back ok besides a fault in the passenger side occupancy module faulty

I see this place mentioned a lot on YouTube channels. I guess he resets modules and seatbelt retractors. He might be able to point you to someone more specific. https://www.myairbags.com/
