I'm a little confused by some of this thread. As I understand it the OP wanted to disable the passive immobiliser only, something I have done on several occasions with no trouble with a Nanocom. Surely the IID tool can do this?

I have never had to modify the engine ECU to turn off just the PI.

blackwolf, it is a little confusing I agree.

Ive also done the PI or PLIP removal with both the nanocom and IID without problems, I can only assume the OP has not done the Renew security ID which could be needed done to repair the modules after the config is changed.

My first post was more to highlight total removal of passive and active immo (total 10as removal) would require engine calibration modification.

Indeed.....this is all I want to do, not disable the immobiliser entirely........

Johnny,, may I ask why you wanted the plips removed in the first place ?

My truck has a recent very intermittent fault where it would not start in France and I needed recovery, It always starts next morning though, it seems immobiliser based, it turns over 3 or 4 times every time, then stops, it does not fire. All the lists and forums seemed to suggest first thing to do was disable the passive immobiliser first......hence why I bought the tool....... 2008 TDCi 2.4 XS CSW

ok makes sense, Im sure I was called about your very car whilst you was away.

To me it seems like you have a wiring fault going on, or a failing 10as module or most common recently an instrument pack pcb failure which does not always carry the immo signal from the 10as to the engine ecu and turn the LED out on the dash also is most cases.


The instrument wire bypass is an easy for a test and can be left like that without it causing problems. see picture below of two wires to join up...

This is not a tool fault, this is a car not playing ball fault of which as you say is intermittent.

Hi Pete, we were in Britanny, it was around 12 Aug I think around 1900 local time......Does the fault become any clearer if I also say recently ie within the last 2 years, I have had a new ignition switch fitted, and more recently the steering box replaced for dripping oil.........? This fault was not evident until these works were carried out ?

Also Pete, I did send you a PM a week or so ago, to see if a remap I bought from you can be added to the tool ? it was originally on the older green/black tool which I still have.....

May be it was the recent IGN switch wirk that's caused it but hard to say for sure.


For mapping info you need to mail me direct, I do not always get PM on the forum when out and about, their is an option to pay a part remap fee and have the remap added to IID yes, but please email me. But for now I think its best you get it going reliably again first.

Am I the only one who reads these posts and am humbled by the knowledge and expertise that some forum members have, whilst at the same time, not understanding a dam word they say. Life is short, so have your pudding first

OK so I have now borrowed a nanocom from someone on the forum, if I reset the 10as using the utility in the nanocom, the truck starts again and behaves normally, if I then go back to the IID tool and only change the passive immobiliser setting to disabled, and write back the settings and then renew security ID, the truck will not start, the immobiliser is permanently on, I can reset it via the nanocom again and the truck starts normally. I can also disable passive immobiliser via the nanocom and the truck starts.

Unless I am missing something here, if I use the IID tool to disable the passive immobiliser, it breaks the 10AS config so the truck will not start, but I can do the same operation on the nanocom and everything continues working.

That's not good, and I look forward to hearing what the experts have to say. If you'll excuse me I won't try the same thing myself in case I have the same issue.

At least with the Nanocom you have achieved what you want, namely the PI turned off but everything else working. You've possibly also discovered a way to make the vehicle harder to steal if you need to leave it parked somewhere!

Blackwolf, if you have time, could you post screen shots of the two settings pages in the nanocom of the 10as settings, I just want to check nothing else has been corrupted, my nanocom has arrived Smile

Also, reading through a lot of threads on other forums, I have found that for the passive immobiliser set to disabled to work, the setting of plip immobilise needs to be set to disabled also?

....HOW TO DISABLE THE PASSIVE IMMOBILIZER
If you want to disable the passive immobilization you have to read the settings by means of the READ
SETTING function, then modify the paramenter PLIP IMMOBILIZE and PASSIVE IMMOBILIZER as DISABLED.
Write the new setting with the WRITE SETTING function.......


This seems to be the only way it works on my green 10as, but I can still set/unset the immobiliser by key fob, so I am a bit confused what PLIP IMMOBILZE disabled actually does?

Its how I want it, ie key fob still sets/unsets immobiliser, but just confused by that setting 2008 TDCi 2.4 XS CSW

I'll see what I can do, but it may take a little while.

I do not recall any issues in turning off PI whilst leaving all keyfob operations as standard, i.e., just turning off the (chronically unreliable) dialogue between the keyfob and the coil in the column.

Unless I change the Plip immobilise to disable also, like some of the instructions on forums say, with just passive immobilise disabled, my dash left hand immobiliser lamp starts flashing after 5 mins or so, so I am assuming that means that PI is still active? Be interesting to see what your plip immobilise setting is......
