TERMINAL DESCRIPTION

Terminal number	Wire color	Terminal sign (Terminal name)	Description	Signal
1	GRY/YEL	RFLFSIG. (RF low frequency signal)	Detects the signal from the right-front initiator	For the first 5 seconds after turning the ignition switch ON (II): pulses 0-2.0 V
				With ignition switch ON (II) for more than 5 seconds: less than 0.1 V
2	GRY/YEL	RR LF SIG. (RR low frequency signal)	Detects the signal from the right-rear initiator	For the first 5 seconds after turning the ignition switch ON (II): pulses 0-2.0 V
				With ignition switch ON (II) for more than 5 seconds: less than 0.1 V
3	ORN	LF LF SIG. (LF low frequency signal)	Detects the signal from the left-front initiator	For the first 5 seconds after turning the ignition switch ON (II): pulses 0-2.0 V
				With ignition switch ON (II) for more than 5 seconds: less than 0.1 V
4	PNK/BLK	LR LF SIG. (LR low frequency signal)	Detects the signal from the left-rear initiator	For the first 5 seconds after turning the ignition switch ON (II): pulses 0-2.0 V
				With ignition switch ON (II) for more than 5 seconds: less than 0.1 V
9	LT BLU	K-LINE (Data link connector)	Communications with HDS	-
10	RED	CANL (CAN communication signal low)	Sends the communication signal	Ignition switch ON (II): pulses
13	GRN	LF LF GND (LF low frequency ground)	Ground for the left-front initiator	Ignition switch ON (II): less than 0.1 V
14	RED/BLK	RF LF GND (RF low frequency ground)	Ground for the right-front initiator	Ignition switch ON (II): less than 0.1 V
15	YEL/GRN	LR LF GND (LR low frequency ground)	Ground for the left-rear initiator	Ignition switch ON (II): less than 0.1 V
16	RED/ORN	RR LF GND (RR low frequency ground)	Ground for the right-rear initiator	Ignition switch ON (II): less than 0.1 V
19	WHT	CANH (CAN communication signal high)	Sends the communication signal	Ignition switch ON (II): pulses
