⌛Y3 Roof Diagnostic System (for all BMW convertible & roadster)

Post by RobbiZ4 » Mon May 10, 2021 11:55 pm

The 3rd generation of my roof diagnostic system got finished in these days, after a conceptual phase of about 2 years:

Just have a look at some pictures on the German ZRoadster forum of the final build phase. :rofl:

https://www-zroadster-com.translate.goo ... st-3233179

One individual Y-cable for each of the 4 CTM plugs leads all signals to an E89 specific concentrator (big blue box) in the trunk.

1st 26-pole Y-cable:

All 4 Y-cables connected to the CTM as well as to the concentrator K1 (BlueBox):

The attached remote control unit supports opening and closing of the roof as well as of the front locking system.


These signals are concentrated on 2 different collections of 16 analog as well as 8 digital channels in parallel.

All 24 channels are transfered by an AD converter to support a specific software on my notebook (on the passengers seat of my Z4).

Advantage:
This tool works completely independant of any fault collection system.
I just have to compare each individual chart with a reference of a well working roof to identify issues on wires, components like hallsensors and microswitches as well as on the timing of the opening or closing process.

That’s handy, does your data logger replay in slow mo so you can see the chain of events?

Yes it does and you can replay the sequence in a later diagnostic session.

But, interestingly that is not required:
There is a live running timeline on the screen, exactly as an EKG at the doctor's. So I've called it "roof EKG".

As the roof in general stops on the first issue, you always will see it live! The timeline continous to run on the screen and all signals keep their current level, low or high.

Taking a hardcopy of the whole window to store it on the filesystem for documentation is all, I have to do
And the source issue of a completely not working roof can be seen in comparing the current view with a former taken reference chart. Really easy going.

The most valued advantage is, that with the help of the jumpers on the green board, I can replace an internal faulty component of the roof with an external attached, working component (microswitch, hallsensor).

I.e. if a wire to a microswitch in the roof shell is broken, I just pull the corresponding jumper and place an external microswitch (MS) on the board. When I switch this external MS manually when required in the roof moving process, the non working roof can be driven into each required position for future repairs.

Thanks.

I'm still astonished by myself about those pictures taken from the build phase, especially this one of the concentrator: :D

That’s a fabulous way of proving the faults....I wonder if we could set up a UK resource by buying one of you plus a licence to use to help UK people ?

Or some other way to enable use of this fab resource?

Robbi, I’m just in amazement and awe with the thought process and skill that goes into devising and producing something like this.

Hats off to you :hattip: :hattip:

    Well, that's all handmade in Germany and can't be payed :D

    Have a look at the initial steps to build V1 of this diagnostic system 3 years ago.
    https://www.zroadster.com/forum/threads ... st-2742452

    The build process didn't change in between, only the complexity.
    Each currently attached box contains an individual electronic board for different purposes, also developed and built by me. Even an Arduino board had to be attached to the signal lines to handle some very strange signals of the lid switches.
    That's the reason, the 3rd version took all in all a bit more than 2 years to build.

    The Arduino box on the left to filter some noises from the digital lines, an inverter box on the right to invert individual digital signals if required (i.e. ground signals can be measured as well).

    A funny picture of the "Inverter Box", equiped with 8 transistor based inverter groups for all 8 digital lines. All 16 analog lines are carried out 1:1.
