Getting around module programming and security by installing set of modules?
Hi All,
I am thinking of installing a set of modules: ECM,BCM,Instrument Cluster, and Ignition swith plus key to get around the programming and security issure covered in several posts where the author wants to replace a failed BCM. Is this a good way to get around prbogramming a new module which may not be compatible with the other ones and the security system? I can buy a salvaged set on Ebay. Thanks in advance with any experience you may have doing this or not doing it for reasons unknown to me.
Thanks, Bill
The BPM doesn’t need to be programmed to the car to run. It just needs to have the same 3 digits after the part number with a “/“. It has to be the same as the original BPM as what’s in your car.
Tbanks for the head's up - that's valuable info as a Body Control Module is a lot cheaper that the set of modules I mentioned. I will look around for one with same 3 digits after the number and let you know how it goes. Thanks for taking the time to get back to me!
Hi again. Seems that all jaguar xj8 2000 BCMs have the same part number: LNC2500CH/XXX which is what I have. I've noticed different years have a LNC2500CG/XXX or AC/XXX. Therefore I asssume per your email that the LNC25000CH/XXX is the one I should get ? or is there something I'm missing about that part number? Thanks.
The /XXX is shown on every BCM (BPM), and also on every other programmable module, and it just means that the unit is programmable. During the factory programming, the "XXX" becomes, for example, "013". The problem is that this number is not written on the BPM itself (and the same case is with all other programmable modules) but it is only shown on the car's "VCATS" sticker located in the trunk, I think at the left side wall behind the carpet. Most breakers/sellers of the Jag modules do not record this number when removing the modules (only very few do) so you will not know what programming number is of the used module you are buying. But, you may get lucky by chance. Example of the VCATS sticker:

This is why this forum is so valuable; info like this is not readily available anywhere else. Thanks!
Hey guys,
I just wanted to mention the experience that I had with my 04 VDP. I ordered a Rear Electronic Module because of a failed Fuel Pump module code that popped on me. I made sure that the part numbers on both units matched up. However, when I got the unit and I swapped it out, my car wouldn't start. The ebay seller said it had to be reprogrammed for my car. Calling the 2 Jaguar Dealerships here in St. Louis, both told me that they don't touch anything past an '06. They suggested a shop that they send people (I'm told they're the shop that bought the old jaguar dealership SDD laptops). When I called that shop, the guy on the phone sharply told me No.
Of course, I decided to tackle this issue myself. 3 months after starting this trip down the rabbit hole, I can officially confirm that JLR SDD v160 installed on a Virtual Machine and a J2534 cable will reprogram the module to the car following an insane number of prompts. I do have access to a '00 XJ8. So it would be interesting if this software can reach back that far and reprogram modules as well. If anyone likes, I can report my work and updates.

Yes that would be interesting to know. Some time back I wanted to get a used ECU programmed for my original 2000 VDP but the shop was unable to; said it would need to be a dealer fix though the dealer no longer worked on that old of a car. Never the less; turns out the problem was not the ECU but was the pedal position connector that was causing the car to go into fail mode at times. Would be interesting to see if the odometer could be changed. My speedo failed with the car at about 95k miles so I got a used on at the junk yard but it had about 150k showing. Certainly would have reprogrammed to the correct mileage if possible.
