When I ran initial start up it did not like my Chrysler VIN number but I proceeded to got through "Drive Authorization" which ends with trying to start the car. I am thinking that when I tried to start the car the anti-theft system didn't like the new ECU with no VIN number and activated the immobilizer. Now that the ECU is programmed properly it may just be that I need to clear the immobilizer which I could do with DRBIII if I had one. But there may be another way to clear the immobilizer. If you guys look at the SKREEM no more thread you will see that superstar had a similar problem and disconecting the battery did not work. he also had to also disconnect the SKREEM module and then the car started right up. Why would disconnecting the SKREEM module work after the battery was already disconnected? Maybe becasue the anti-theft system has its own secondary battery?? How many of you knew your car has two batteries? this is why disconnecting the battery will not kill the alarm siren. I think if I disconnect the battery and the secondary battery that would have the same effect as unplugging the SKREEM module. I would prefer to not tear apart my dash to get to the SKREEM module if I can just unplug the secondary battery.
