Analysis of BMW CAS4/4+ decryption data failed
Question: When reading CAS4/4+ by ICP and all pin detection passes, Why the data cannot be read?
Specific tips are as below :
Answer: If the above problem occurs, the decryption progress bar will reach 100%. But in normal cases, the chip decryption progress bar will not reach 100%. At the moment, it is necessary to check whether the C-GND probe on the interface board is removed or cuted. Reinstall the interface board to read the data once
The C-GND pin interface board locations are shown as below:
