Strange devices (for me at least...)

#1 Post by Dorchester » Wed Nov 04, 2020 3:29 pm

I'm puzzled by both green & yellow devices close to the fuse box and the ECU big plug in my 1994 214i cabby: :S

What could they be? :tumbleweed

Thanks. :)

Yep. One is the 5AS, the other (I assume) is MEMs.

So you can mess around with this using something like this.
Also needed: a laptop and one of these: Image

Yup, diagnostic connectors. You’ll also need software such as PScan, or a T4.

Thank you all! :clapping
Then I've got 4 more questions:
- were those devices commonly fitted on 214 at that moment?
- which of those 2 should be preferred (and which is which BTW - green & yellow - 5AS & MEMS 1.6)?
- Would you provide a link for the cable? I can't find any with the right end going to the ECU.
- is there any mean to connect a Bluetooth device instead of a laptop?
Thanks a lot. :D

The cable is a DIY or at best a cottage industry device. I made my own about 5 years ago. I had to order the connector from Mouser in the USA!
The software is enthusiast-brewed, so you'd have to hope that someone out there has done what you desire. Or become the pioneer who produces it!
The source code for some parts is available; I was able to compile it for my laptop, with some edits to suit my particular wants.

I've E-mailed to James Portman thanks to the link you provided: https://rovermems.com/#cables
He'll send me the cable for £29.99 (One was available on Ebay for twice that price!), postage for France included.
His Android software is free of charge that I've already downloaded.
And he told me that the green plug on my pictures was intended to work with the alarm (but what to plug in here and for which use??? :S ), and that the right one is the yellow one.
I've just to find a convenient converter cable from USB to mini USB (phone).
Last thing to find out: a short way from the engine bay to the passenger compartment (LHD).
Thank you all once more. :D

As said above green plug is for alatm (5AS in your case). Same plug goes to yellow (ECU) ang green (alarm). connectors. However you need to have software able to speak with it what pscan should be (or T4 but that is another story). I do not know any freeware software able to speak with alarm.
Use for it would be to add new fobs if existing break or you loose them, read EKA code or match alarm ECU with engine ECU for engine mobilisation purposes.

Thank you.
James' software is here: https://rovermems.com/#software
As you can see there are 2 versions: one for laptop & one for Android phone.
I would not make any mistake with a sophisticated software like pscan. Moreover all my laptops are working under Linux Ubuntu and it's unlikely that any software was written for anything but MS Windows or maybe Apple.
I just need monitoring the ECU with simple data such as coolant temperature and the like.
Wait & see... :)

Just received good news from James. He told me he'll send the cable today. :D

Just a note that pscan works under Linux, MacOS and Windows.

Then buddie you've made me flabbergasted! :o
Gobsmacked that something here may work with Linux.
Thus I'll have a look on that pscan you're praising so much. I'm not that stubborn... :tongue
Only rock in my shoe: far from being free (everybody should make a living, I understand that easily) it comes at a price, £159 + shipping. :scared
Not sure on my side it'll be that cost effective on a 214 with no ABS, no air bag and very few electronic features... :huh
You know me a little now don't you? I'm never crazy about tricky systems hard to manage and/or understand. The simpler the better as usual... :D

At present pscan in my case have use only with my R3. I still have no use of it for my R600. However in your case usage could be much, much greater, since pscan have R25, cabrio and R75. Pscan can talk to many ecus from your cars, look on the list. However, it is your choice, I am just telling what is available on market.
Maybe in your case start with free software and see if you have need to go on.
