Programming Failure
Issues may arise after installing a factory Mechatronic kit when trying to program the module after installation. The case sleeve that comes with the valve body from Mopar is not to be used! Mopar states that the sleeve does not allow the vehicle harness to make contact with the pins of the Mechatronic unit, and this does not allow the Mechatronic unit to be programmed. It is advised to use the old sleeve.
