Problem:
I have not been able to read Porsche Cayenne BCM with
Xhorse VVDI Prog programmer, followed the wiring diagram to connect BCM and selected chip BCM 5M48H R/W/UNLOCK to read data. vvdi failed me and gave crack error:
Incorrect crack. Please confirm the type of chip. Check the connection and try again”
Photo attached:
When read Porsche Cayenne 5M48H, don’t select BCM 5M48H R/W/UNLOCK option but CAS4-5M48H-BACKUP instead.
It reads safe and won’t lost data.
