It is a 2014 Porsche rear body control module (BCM). It is water-damaged and needs to be cloned.
The chip is mc9S12XET512 with 3M35J secured mask. We tried to read this BCM with CG Pro 9S12 programmer.
The chip is covered by the XP400, however it failed to read it. The xp400 pro is known to delete or mess up the D-flash when reading the module. A good friend of mine actually suggested CG Pro and the reason why he
suggested that because he said that one is really good with the MC9s12 chips the secured and encrypted chips.
VVDI Prog is supposed to have more coverage than the CG Pro. However the CG Pro will read that he vvdi prog will fail to read.
Go to Model->Immobilizer->Porsche. Body control module is part of the Immobilizer Porsche. Go to 2M25J because we believe 2m25j and 3m25j are the same ID. They are the same ID based on even vvdi prog read this 3M25J.
Go to wiring diagram choose either metal or ceramic. It is ceramic. Ceramic is this little piece right here.
Cut this line and remove this comp component, remove this component.
Did wiring according to this diagram. When we are on this selection, we will be able to read D-flash.
Here it says 3M25J which is right ID. It reads successfully and click OK to save it.
This is the D flash. Then we to back up P-flash. We can read the Pflash (BCM-2M25J PFlash Backup) as well and save it.
We are able to get a good read.
Then we try to read the donor BCM. Connect the donor BCM with cg pro according to the same wiring diagram.
Back up eeprom and flash.
Then write original flash to the donor BCM.
Clone BCM successfully.
