B2192 ID DISCORD, IMMU-ECM
DescriptionINFOID:0000000003814948
BCM performs the ID verification with ECM that allows the engine to start. Start the engine if the ID is OK.
ECM prevents the engine from starting if the ID is not registered. BCM starts the communication with ECM if
ignition switch is turned ON.
