Component Designations

Component	Abbreviation in Guided Fault Finding	K- Repair Group Number Diagnosis Address	Notes
Engine Control Module 1 -J623-	ECM1	K01 01 - engine electronics	Engine control module 1 is active in the immobilizer and must be adapted if it is replaced. Communication takes place via the data bus drive.
Comfort System Central Control Module -J393-	ICM	K05 05 - access/start authorization	Body control module 2 contains diagnosis addresses 05 - access/start authorization and 46 - Comfort System central module. Therefore there are both K-repair group numbers K05 and K46. The immobilizer and component protection are included in address 05 - access/start authorization and must be adapted if body control module 2 is replaced. Communication takes place via the data bus-Comfort.
Comfort System Central Control Module -J393-	BCM2	K46 46 - central module Comfort System
Access/Start Authorization Switch -E415-	Ignition Lock	--	The ignition lock is electronic, which is connected to body control module 2 via a LIN-bus. The ignition lock must be adapted if it is replaced because it transmits the immobilizer information from the key.
Electronic Steering Column Lock Control Module -J764-	ESL	KG1 05 - access/start authorization	The electronic steering column lock is connected to body control module 2 with the same LIN-bus as the ignition lock and does not have its own diagnosis address. It must be adapted to the immobilizer if it is replaced. The diagnosis is performed by address 05 - access/start authorization. The electronic steering column lock can be replaced separately without having to remove the steering column.
Engine Control Module 2 -J624-	ECM2	K11 11 - engine electronics II	Engine control module 2 is active in the immobilizer and must be adapted if it is replaced. Engine control module 2 is installed as an option and is dependant on the engine code. Communication takes place via the data bus drive.
Transmission Control Module -J217-	TCM	K02 02 - transmission electronics	The transmission control module is active in the immobilizer and must be adapted if it is replaced. The transmission control module is installed as an option. Communication takes place via the data bus drive.
Data Bus On Board Diagnostic Interface -J533-	Gateway	K19 19 - diagnosis interface for the Data bus	The gateway is passive in the immobilizer and does not need to be adapted if it replaced. The gateway serves as a router from the data bus-Comfort to the data bus-drive.
Key -KD5708-	Wrench	--	The vehicle keys are active in the immobilizer and must be adapted if they are replaced. Up to 8 keys can be adapted.
