1956 Dodge Sierra Wagon - Feb 13, 2009

Down to the real PITA problem!

As it turns out, the Durango came equipped with the latest security system technology that wirelessly reads an encrypted code located in a chip in the ignition key and compares that with a code that is generated by the PCM that is based upon the VIN number.

Humm, need to find someone that can remove this feature from the PCM or find a software program that can disable the code. Not so fast there... none of the dealers in my area would touch it. None of the turner programs were capable of wiping it out. I finally found a hacker that claimed he could take it out, but he was charging almost the cost as a new PCM to wipe it and reprogram it... not good!

Plan B, all I need to do is remove the wireless transmitter and it's associated wiring that is around the ignition lock on the column and hide it somewhere under the dash in the 56 and all would be good... bzzzzzzt

The 2005 Durango was the 1st Mopar to be converted over to the "new and improved" CAN bus and as it turns out, the security system uses the CAN-B and CAN-C buses to communicate with the PCM. So to make this work, I would need to pull the front body controller (another computer which controls the CAN bus) and most of the rest of the wiring harness from the Durango. What should have been clean and simple, and would have been IF I had used a 2005 Dodge 1500 truck as the donor, was now a huge ugly mess.
