e89 ctm wiring diagram

[BatmanReturns]

Hi All,
Does anyone know where I can get a copy of the e89 ctm wiring diagram. In particular I am looking for the pinout for the 26 pin header (on the CTM) in respect to the microswitches & hall sensors. I first reached out to my local dealership, they claim to no longer have a copy of it. Next I went to TISUI, that's a bit of a let down. Next I turned to AI & Google and found this site. So, anyone have any suggestions?

Thank you in advance!

Thanks Chippie,
I believe that has the pins in question. I believe this will work.

Thank you,

The diagrams Chippie posted are exactly what you’re looking for – the 26-pin CTM connector pinout with microswitches and hall sensors labeled. Check especially the third image – all the key signal lines are clearly shown.

If you need more detailed functional breakdown of each pin, let me know – I can help decipher it using additional sources

Thank you! I will post an update as soon as I have a free weekend to tackle this beast…most likely at the end of the month.

Hi Mick

Yes

Just had a look at ista mine doesn’t go into detail on hall sensors

Would you be good enough to have a look please and tell me what pins the two hall sensors on the right hand ram go to on the CVM please?

One is yellow and brown the other is red and brown wiring

I need to do some continuity checks

Thank you

I wonder if the hall sensor I am having issue with is the one named closing rear interrupted

I haven’t had chance to look in ISTA but here’s a Dropbox link that Anubiszed had previously posted

Let me know if it’s any good, if not I can look at ISTA later.

Ive seen that one and its not detailed enough

I think I've managed to find it on newTIS... but thanks for replying

Interrupt Hall sensor seems to trigger a stop and slow down save the boot lid crashing as it closes.
The other Hall on that ram i had problem system freezing roof in boot, boot lid open, it's connector pulling apart as it had no locking mechanism.
I pushed it back in super glued and extra cable tie, no problem since.

Good shout I’ll check the interrupt one

Where is that located?

Just in case you haven’t found it or it may help someone else


Sorry the picture quality isn’t very good, I can’t figure out how to get it full screen on my laptop

Thanks Mick!!

Chippie, this is exactly what I needed, thanks! I rewired both roof arms and put new hydraulic lines in. It worked once and then it froze closed and now that I’ve fixed the codes that were being thrown the buttons don’t do anything. Don’t even change state on ISTA or my Foxwell nt510. I’m hoping it’s something simple.
