Ultimate Remote with OEM key-fob owners please note **UPDATE by raistlin (Page 1 of 5)

There's a possible problem with the ultimate remote when used with the OEM key-fob I'd like people to be aware of.

I've had two reports now of the car windows being down and the car unlocked within a few seconds of having locked the car.

This does NOT happen on the version which uses the third party remote control TX/RX.

If it is going to happen it seems to show up very soon after initial installation so if you've had it fitted for a while I don't foresee any problems like this.

I'm satisfied that the modules are serviceable and suspect the fault is caused by a spurious signal or an intermittent earth fault in the car's wiring.

If this happens, pull the fuse within the module to disable it. All normal functions will continue to operate unhindered. Please let me know.

As I said, I've only had reports from two installations but I thought it right to let you know.

OK, I think we've successfully ironed out this little gremlin... at last :)

There are one or two modified PIC chips in use at the moment and have been for varying lengths of time and I'm now satisfied that these modified chips have solved the problem.

Replacing a PIC is a reasonably simple task which just requires a degree of dexterity and a modicum of patience.

Basically, this problem only ever arose when the UR was used with the OEM key fob and is down to the fact that it sends to different sets of signals at the same time which on occasion could confuse the BCU (Body Control Unit).

The modified PIC has a timer incorporated which means that, effectively, 500 - 1000 milliseconds after the operation of the key-fob and initial locking of the car, the UR section kicks in and takes care of the windows, sunroof, powerfolds etc. That 500 - 1000 millisecond delay is sufficient for the BCU to differentiate between the signals and to act appropriately each time.

The modified PIC has been released to service as it were and details of how to claim a free modified PIC will be made available on the ThinkTank web-site in due course.

CAVEATS:-

1. You will only need this updated PIC if you use OEM control. If you use a third party remote then it is not required as the circumstances whereby the BCU might become confused will not occur.

2. This PIC will only work with the later UR modules where the PCB (Printed Circuit Board) was modified to include ignition controlled inhibition of the module to overcome the problems caused if speed locking is enabled.

The way to confirm whether you have the later module is to look at it and see if there is a THREE WAY connector on the PCB. If there is then you have the latest module. If not then you will have to replace the module.

It is unlikely that those using the OEM key-fob will have the older module as the module design was changed at much the same time as I worked out how to get the UR to work with the OEM key-fob :)

Thanks Paul,
I got a new chip, V3.1 in February, would this be the latest version, or has there been a further update?

You have the latest version if you have the time delay Joe.

Paul! how about if I ask! what is an 'ultimate remote' ?

...... and what is a third party remote control TX/RX?

Is this something I should know about ? Is this equipment fitted to my car ?

Ooops. It never occurred to me that you wouldn't know what it is :em: Sorry :(

As Andy says, the best thing to do would be to have a look at my how-to documents on the link he's given you.

Any remaining questions, I'd be happy to answer :)

Paul, Andy! thanks chaps :thumbsup: ................. and I thought I knew a few things about electronics, well! nope not after flicking through those detailed PDF's (thats gone right over my head), we're not worthy comes to mind Paul. :rolling:

The global window opening/closing is something I miss alot, had it on the wife's Galaxy and it was very handy at times.

So to get these options active on the 75, its a case of following your 'How to' then Paul..................... So who wants to come and do mine then....... ? :thumbsup: :clap:

Paul, Mine still randomly opens my windows for me and bounces the locks. Will a later pic chip fix this ?

Hi Mr L Mine was one of the prototypes and did the same, anyway as I inadvertently stuck 12 up the neg wire (don't ask) it subsequently died. Replaced it last week with the new version and it seems to have stopped the problem, then again it's only been just over a week :)

Hi Dave, hope you are well mate :) I am not sure which level mine is tbh, I wasn't the first to get the mod fitted. Touch wood when Paul pops in all will become clear.
