Bricked TRSVC Module??

[95wildtt]

Hi,

I've been working on an RFK to TRSVC camera retrofit (I had a correctly working RFK camera except for it being in Black & White with my NBT EVO display) and have everything installed and the old module removed from the X5 (2008 4.8i).

I can't get the new TRSVC module (bought used off eBay Part# 9291386) to work correctly. Also, the PDC button blinks on/off when in reverse and there is no picture on the screen from the RV camera, although the camera controls are on the left side, and the PDC is working like normal (other than the blinking LED above the button). So the module is being seen by the system...

I have coded the various modules with the new FA (tried $3AG but then the both the RFK & TRSVC modules show in ISTA+) with $3AH and have the TRSVC module correctly reported in the tree in ISTA+... The module reports its info (part number, SW etc) correctly but I can't access, test it or reset it. I also can't read or write it in NCS, just as a another data point. I can access all of the other modules in the X5 and perform any type of diagnostics without any issues.

I've verified all of the wiring and power to the new TRSVC module several times, and since the module is seen in ISTA+ and reports its info correctly I believe the CAN connections are working OK.

Could the mdoule be "bricked" or damaged in some way so as to not work correctly? This seems very odd to me...

I have another TRSVC module on the way tomorrow (Part # 9236527) and will try to replace the first module with the new used one and see what the results are.

Will report back.

Any ideas/suggestions?
What modules should I have coded?
(I've coded CAS, FRM, IHKA, JBFF, PDC & KOMBI with the new FA)

Thanks,
John

Update:

In case anyone else has these issues...

Note that if you are working with a Pre-LCI X5, as I was, you also must do the folllowing:
1. Replace the JBBF (Junction Box module under the glove box) with a newer LCI module
2. Extend all of the PDC sensor wires from the old PDC in the Left rear area to the new JBBF module (which has the PDC built into it)
3. Remove the old PDC module
4. Code the new JBBF module

Enjoy,
John

For some reason I can't code the TRSVC module, it wont read in NCS Expert...

Any ideas?

Hi i'm in the same position as you ,I had a correctly working RFK camera and PDC,TRSVC module correctly reported in the tree in ISTA+. Also, the PDC button blinks on/off when in reverse and there is no picture on the screen. I have CIC Retrofit on X6 2009 Pre LCI.
My question is should i
1. Replace the JBBF (Junction Box module under the glove box) with a newer LCI module
2. Extend all of the PDC sensor wires from the old PDC in the Left rear area to the new JBBF module (which has the PDC built into it)
3. Remove the old PDC module
4. Code the new JBBF module
Thanks

Hi kancho,

I got your 2 PMs also, sorry for not replying.
Yes, you will to do all of the work outlined in these 4 steps in order to get this to work OK.
It will work, but will take a lot of time and patience.

Sorry for the late response,
John

Thank you ,Is everything right with you car? Did you find a way to program the module? Thanks again.

I can confirm that you cannot read or write to the TRSVC in NCS ... it takes something like Tool32 or WINFKP to do that along with an ICOM, but I am glad you mention that there is nothing to code in it!

I am at present retrofitting Top View $3AH and have a few problems but we think it’s hardware, either cables or CIC pinouts ... getting there but what a drama!!

The thing I want to ask is what steps you need to take to code a later JBBF to a car that never had one ... I am going to do this to another E70 pre LCI and no one is able to run the procedure past me ... I reckon I know what to do but a heads up is always good!!!

I know the rewiring that needs doing, from F & R sensors to the new JBBF and have studied it at length, just not quite sure on how to code a unit that is new to the vehicle ... is it difficult??

Many thanks ...

Hi,

You will need to code the new modules with all of the option codes that your X5 has with NCS as the first step.

Then you may need to change a few of the settings in your new modules to match those in the old module.

Thanks John, I understand the need to change some settings after fitting the new module but more importantly its the coding procedure to actually change the module that is beating me ... I have read many posts of various forums and think I know the way round getting the vehicle to see a module it didn’t have originally, i.e. a module that was fitted to a later model.

I am assuming you need to alter the build date in NCS so it can find the right Daten?
It’s this bit that I cannot quite work out ... any tips?

Thanks again for replying ...

Hi,

Yes, you will need to change the build date (I used #1011) and then VO code the module.

Here is a tutorial on changing the VO:
