Step 1: Make Connection 

You should have ACDP Android/iOS mobile App downloaded and Porsche authorization opened before operation.
Connect ACDP device, OBP+ICP adapter, BCM interface board and BCM module.
Check the crystal oscillator package of BCM module:
EXT1 short-circuited for ceramic packed crystal oscillator ; EXT2 short-circuited for metal packed crystal oscillator.



Step 2: Read PFLASH data
Open ACDP App
Select Porsche function->Add key for new Porsche->ICP IMMO->MC9S12XEP100 (Mask 1N35H)->Add key (auto mode)
