Signal Specification, Infotainment Control Module (ICM)

General 

All the values given below are between the respective terminal in column 1 and terminal #A11 in column 1 (power ground) unless otherwise stated in brackets after the table entry.

U=	DC voltage in volts (V)	UAC =	AC voltage in volts (V)
Ubat =	Battery voltage (V)	f =	Frequency in Hertz (Hz)
Ulow =	Voltage approximately 0 V	t =	Time in seconds
PWM =	Pulse width modulated signal in %

Breakout box terminal	Control module terminal	Signal type	Ignition on	Ignition off	Miscellaneous
#25	#C1-1	30 supply	U = Ubat	U = Ubat	Input signal.
#26	#C1-2	Signal reception, ICS IR			Input signal. The low-pass filter in Infotainment control module (ICM) only lets past frequencies below 2 kHz.
#27	#C1-3	Secrecy mode telephone	U = Ulow	U = Ulow	Input signal. When the secrecy mode signal is grounded, for example, in case of incoming calls via external accessories such as handsfree, it leads to the Infotainment control module (ICM) reducing all sounds automatically.
#28	#C1-4	Reserve			-
#29	#C1-5	Reserve			-
#30	#C1-6	Ground, ICS LED	U = Ulow	U = Ulow	Output signal.
#31	#C1-7	Signal ground, ICS	U = Ulow	U = Ulow	Output signal.
#32	#C1-8	Voltage feed IR-sensor, ICS	U =5 V	U = Ulow	Output signal.
#33	#C1-9	Voltage feed, ICS LED	U=1.2 - 3.3 V	U = Ulow	Output signal. PWM 225 Hz
#34	#C1-10	Control, ICS	U = 5 V	U = Ulow	Input signal. Analogue input signal from ICS resistor step.
#35	#C1-11	Power ground, voltage feed	U = Ulow	U = Ulow	Input signal.
#36	#C1-12	LIN SWS	U = 5 V	U = Ulow	Input/output signal.
#37	#C1-13	CAN H#1	U = 2.5 - 3.5 V	U = Ulow	Input/output signal.
#38	#C1-14	CAN L#1	U = 2.5 - 3.5 V	U = Ulow	Input/output signal.
#39	#C1-15	CAN H#2	U = 2.5 - 3.5 V	U = Ulow	Input/output signal.
#40	#C1-16	CAN L#2	U = 2.5 - 3.5 V	U = Ulow	Input/output signal.
