				Number of adapted keys up to a max. of 8 keys
			Key condition OK 1 = yes, i.e. a structurally legitimate fixed transponder code could be read (regardless of whether it was authorized or not) 0 = no, i.e. no structurally legitimate fixed transponder code could be read
		Engine Control Module (ECM) responding 1 = yes (regardless of whether ECM is authorized or not) 0 = no, i.e. Engine Control Module (ECM) is in after-run1)
	Start procedure permitted 1 = yes 0 = no, i.e. ignition key is not adapted or incorrectly adapted or the Engine Control Module (ECM) is incorrectly adapted or malfunctioning

1) Depending on the Engine Control Module (ECM), the measuring value block registers position "0 = Engine Control Module not responding" for 10 to 30 seconds after engine and ignition are switched off, i.e. ECM is switched clear and there is no malfunction. Initiate On Board Diagnostic (OBD) again to be sure. Refer to Anti-theft immobilizer On Board Diagnostic (OBD), initiating .

				Anti-theft immobilizer status 4: Customer service new; delivery condition of customer service (instrument cluster = replacement part) 5: Customer service locked; adaptation data programmed in customer service 6: Anti-theft immobilizer adapted, normal functioning condition 7: Key adaptation active; key adaptation via tester
			Fixed code authorized 1 = yes 0 = no, i.e. fixed transponder code of key is not authorized
		Key status (transponder) 1 = Transponder in key is locked, i.e. computational rule in key can no longer be overwritten. Key can no longer be adapted to a different anti-theft immobilizer system. 0 = Transponder in key is not locked, i.e. transponder has not yet been adapted to instrument cluster (new replacement part key).
	Variable code authorized 1 = yes 0 = no, i.e. variable code is not authorized (computational rule for variable code is not yet the same as that in the instrument cluster).

				The transponder recognition locking time indicates how much time must pass before a transponder recognition is possible again. This lock is activated after an unauthorized key is detected 20 times in a row. 0 to 10 min1)
			vacant
		The Engine Control Module (ECM) locking time indicates how much time must pass before an adaptation can be performed by the Engine Control Module again. If the 7-digit PIN is entered incorrectly three times while adapting channel 50, the control module is locked for 10 minutes 2). 0 to 255 min1)
	The instrument cluster locking time indicates how much time must pass before a login procedure can be performed again. If the 7-digit PIN is entered incorrectly three times during the login procedure (adaptation of vehicle key or used instrument cluster), the control module is locked for 10 minutes 1). 0 to 255 min1)

1) Read function where applicable.

2) This time is doubled after every third consecutive incorrect attempt, up to a maximum of 255 minutes.

	CAN-communication to Engine Control Module (ECM)1) 1 = yes 0 = no, i.e. no CAN-communication between control module for anti-theft immobilizer and Engine Control Module (ECM) - Key adaptation not possible
