How-to: 2010 Dodge Grand Caravan used pcm swap with OEM wiTech and Micropod 2 VCI. The program is WiTech 2.0. Replaced WiTech 1.0 requires a secure Micropod 2, active License to use WiTech 2.0 attached to your Micropod and active subscription to FCA Tech Authority.

Vehicle Model:
2009 Dodge Grand Caravan 3.3L V6 OHV
VIN: 2D8HN44E89R653374
Prepration:
4-digit pin code (you can pull pin by OBD2 based device, like Autek ikey820 or Xtool X100 PAD2, both work great on Chrysler group)
The PIN entered was the 4 digit secret key code. When the PCM was replaced on this vehicle theres a 4 digit key code (security related) that needs to be transferred from the WCM to installed PCM. There is a function tab on WiTech 2.0 under the WCM miscellaneous functions that is “PCM Replaced” WiTech checks the ignition status then the 4 digit key code is entered WiTech verifies the correct pin code was entered then transfers the PIN to the PCM allowing the PCM and WCM to shake hands for a lack of better terminology and allowing the vehicle to start and run. For the PCM Replaced Function the Correct Vehicle VIN is checked as well.
