B2192, P1611 ID DISCORD, IMMU-ECM

Description

INFOID:0000000001034107

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 and starts the engine if the ID is OK. ECM prevents the engine from start-
ing if the ID is not registered.
