B2194 ID DISCORD IMMU-I-KEY
DescriptionINFOID:0000000001404072
BCM performs the ID verification with Intelligent Key unit that allows the engine to start. BCM starts the com-
munication with Intelligent Key unit if ignition switch is turned ON and starts the engine if the ID is OK. BCM
prevents the engine from starting if the ID is not registered.

DescriptionINFOID:0000000001404180
BCM performs the ID verification with ECM that allows the engine to start. BCM starts the communication with
ECM if ignition switch is turned ON starts the engine if the ID is OK. ECM prevents the engine from starting if
the ID is not registered.
