The ISN # and Password field in the EWS program showed ERROR_ECU_REJECTED for both the working DME and the used one. I hit F1 to write ISN went back and proformed rest and store, with still no luck. The only menu option in INPA to program ISN number is in the EWS section under activations. Therefore I concluded that the password in the DME's were different. I then replace the DME and tried the same thing and the engine would crank but not start. This align's the value in both the DME and EWS to the first value, but really does program anything.
Remember I flash both units with SSS hoping to rewrite the memory area, and changing VIN number in the used DME.Īfter synchroizing the OE DME by restting and storing the DME start value in the (shift F6) menu option of the DME section the engine would start.
I first read the orginale DME with INPA and notice that everything matched in the info and coding pages except for production date. So now that I fix the vehicle and purchase a used DME a wanted to see if I could program the used unit to the car. Lucky me that there was a smell of burrnt in the car which led me to it. Of course this led me to consider the DME as the fault, but as it turn out it was the Body control module that was shorted out causing the network to go down. Vehicle had a memory error code which did not allow the TAC unit to accelerate off idle. Ok I have tried to program this used DME with INPA and this is the results.įirst off in my case I am working with 2000 BMW 323i with MS42 engine and the chip is AM29F400BB with EWS 3+.
