engine rough or stalls[ incorrectly fitted ckp]

There is no back up for the ckp, if it fails, engine stops and will not start.
Mate,I 'm certainly not an expert, but I can highly reccommend buying the RAVE cd for your vehicle. Bob

I have changed the CKP for a new one and no difference.
I do have a rave CD, just can't find it at the moment

I seems still to be something to do with ECU immobilized..

If I read the settings for the Immobilizer it has nothing in the fields for year, week and serial number. They are all blank.
That doesn't look right. but would need to confirm by someone looking in their ECU at the same spot

I have had a defender Td5 10AS alarm ecu fail, intermittent immobilisation and all that. This is the unit that generates the unlock code to the engine ECU to enable it to start. It is behind the dash binnacle against the firewall, a green box.

I read on one of the UK Land Rover sites that a bad earth on the ECU can cause issues like this.
Might be worth a check

Justin are all AS10 s the same was interested in getting a spare and will be at TRS this week

no, there are 2 frequencies, 315mhz and 433mhz. there are also a few changes over the years adding and subtracting features iirc. best thing to do is read the part number off yours, and get another one from the same model year.
if you want, pm me the part number and i'll see if i have one?

Hi Justin, I have been looking at the green box wondering what it all means !!

Mine says

AMR 6430
10AS-315
52010379A
1279253
27/00


In Nanocom if I go to:
def alarm
setting
read settings

Under alarm coding data down in the bottom section I have nothing.
The first 3 fields are year , week, serial number

I am assuming that each green box has its own serial number and year and week that must be put in for it to work ??

Looking at my numbers above could the year be 2000 and 27 for the week ??

I have checked the earth on the battery across to the ECU case and there is 0 ohms between them, or are we talking a different earth (I would be surprised if any earth coming in on the plug is not earthed to the case anyway)
