Has anyone found a procedure to program the engine computer to work with the chip imbedded in the key?
I keep getting codes indicating that one of the circuits in the ECM (Engine Control Module) is bad. I purchased a used ECM from a jag salvage yard, but car turns over but will not start. I have been told that the key has a chip in it and the ECM must be programmed to communicate with the chip.
Jag dealer says to bring in the car, well that is an hour tow truck ride. Take the replacement ECM out and install the original and car will start, but only run as restricted performance.
I have not talked to dealer about bring the replacement ECM and the key yet. Wondering if the only option is to bring the car to the dealer.
Does anyone repair these ECM's?
There used to be a shop in Houston that I had one repaired for an XJS, but have no information on if they are still in business or how to contact them.
