Landrover Defender 2.5 TD5 2004 - Replacing ECM with used unit? - Fixed #

Posted by Keith Brown on December 31, 2014, 9:36 am

Year of Manufacture *: 2004
Engine Size and Code *: 2500
( Optional ) Scanner Used: dec 3

as above is this possible to purchase a used unit & reset vin & immi codes
The dec 3 "says" it can re-right injector calibration & security status but has anyone had success with the dec
also will a used unit accept new vin id?
your thoughts would be very helpful thanks keith

Not easy if you haven't done it before, you need hot air to remove it, and is probably coated with laquer that needs removing first.

Open the ecu and look for a small chip half size of your smallest finger nail, 8 legs and should have 93C46 on it, see what you think.

Or do you have any local tuners near you, all decent ones have this gear, you're welcome to send them to me if you get stuck.

I don't know where you are in the country, but if you are anywhere near me I can do it either way ( T4 or EPROM)

Hi Keith,

Yes I know it can be done with the dealer kit which is T4 on that vehicle which I own and have used for that very purpose.

DEC should be able to also perform that task, which I also own but I don't remember ever trying to match a second hand ECU to that type of vehicle with it.

Without either option available then swapping the EPROM's over would be the next local step.

Sods law, I'm in Wiltshire

Mark

Yes- The DEC will perform the procedure and then re-input the injector codes after swapping.

I have done a few of these now and fitted second hand units - works ok everytime.
