I fix stuff

T6 Pro
I've just got done coding the tailgate conversion. performed an auto scan and a few faults popped up that I need a fresh set of eyes to go over. Central Elect and Instruments. I cant see any symptoms with regards to the door modules can errors, everything seems to work as it should. Same goes for the instruments, software issue??

here's the scan. any help appreciated.

Have just noticed something, when you unlock the van and open the sliding door only, the central locking auto relocks after a few seconds, so it isnt recognising the sliding door being open. Pretty sure it was before i sausage fingered the coding.

It's on the left/nearside/passenger side. But i didn't know what perspective vcds used i.e right side looking at the front of the van or from the drivers seat. It's also an option in the can gateway installation list.

The link that I posted is for a T6 California which has a sliding door on the right hand side. It's from the drivers seat.
 
I'm not too sure but I think 0D under 19 in the CAN gateway list is for an electric sliding door. Maybe someone with more knowledge than myself can help.
 
Just had a search on ross-tech and Left/Right is taken from a sitting occupant facing forward.

Did you scan the van before any modifications?

I thought i did, but i cant find it, must not have saved. i do have one from last year, the media unit has been changed since and had some coding done to make it work, but the unit died. I've fitted an alpine HU since so any media info may be out dated or NA

Check the folder called logs within the VCDS install directory you should find all your scans there

I did find a newer scan before id fiddled with the tailgate coding that may help

ALL the scans ever made (even not explicitly saved) are stored in Scans subfolder = C:\Ross-Tech\VCDS\Scans or if Beta-version was used at some point then the scans are in folder C:\Ross-Tech\VCDS-Beta\Scans

Looks like i didn't do a before scan o_O

I changed the sliding door from right to left now and it now recognises the door opening and closing, so another step in the right direction.

The door controllers (subsystem 1 & 2) are lost - how did that happen? Does central locking work, electric windows, mirror adjustment?
Also multi-function steering wheel controller (subsystem 3) has disappeared? Do the buttons work?

No idea how they would be missing.

The van did not come with a MFSW i retro fitted that, ran the new wires to the bcm, coded it and it works.
The central locking works. I havent tried the mirrors recently but im assuming they still work.

Can the sub systems be reinstated?
 
ok so I just went through the scan logs and found one I did a few days after I got the van.

I notice that the BCM coding is obviously different. Also 19 Can Gateway has different Coding. Shop# and VCID are different to what they are now.

Update... I've managed to sort out all the faults apart from one. The one that remains isn't a fault so much as an indication that i no longer have an original headunit/media unit.

The loss of comms with the door modules was due to a bent pin 17 on the bcm.
The undervoltage fault i managed to clear by resetting the adaptation values for energy management.
