2.1. Noun explanation

BMW : Bayerische Motoren Werke

EWS : Immobox used in earlier BMW cars

CAS : Car Access System(40 unit), mainly include CAS1(0K50E), CAS2(2K79X),
CAS3(0L01Y), CAS3+(0L15Y, 0M23S), CAS4(1L15Y, 5M48H, 1N35H), this
document will only use CAS1, 2, 3, 3+, 4, 4+ to express,
don’t write detail mask. If
document have detail mask indicates the special explain to this type

FEM/BDC : Immobox used in some new BMW models after 2014(F-Series)

OBDII method : Connect BMW TOOL to car with OBDII interface

CAS PLUG: It is not a standard device, need buy for extra. Communication with
CAS through CANBUS 100Kbps.

CAS3+ encrypt version: Sometimes we call CAS3++. When the car (not encrypt
version) start, CAS will verify key, ECU will verify CAS. But for CAS3++ type, ECU will
verify key in addition. So add key for this type need working key or ISN support. For
the above reason, the introduction for CAS3+ is also applicable for CAS3+ encrypt
version. Expect write no applicable for CAS3+ encrypt version

ISTAP Version: Strictly, ISTAP belong to CAS3+ encrypt version, the only different is
that we cannot read CAS immodata by OBDII for ISTAP version.So the introduction
for CAS3 encrypt version also applicable for ISTAP version, expect write not
applicable for ISTAP. Fortunately, we can OBDII read ISTAP CAS immodata by
update CAS flash. VVDI2
– BMW update ISTAP version flash only need 10
minutes.

ISN: Identification Serial Number, this value use to verify ECU with key. 16 bytes

