					After 5 seconds with ignition switch ON (II)	0 V
2	WHT/RED	RR LF SIG. (RR low frequency signal)	Detects the signal from the right-rear initiator	2-GND	For 5 seconds with ignition switch ON (II)	Pulses 0-2 V
					After 5 seconds with ignition switch ON (II)	OV
3	ORN	LF LF SIG. (LF low frequency signal)	Detects the signal from the left-front initiator	3-GND	For 5 seconds with ignition switch ON (II)	Pulses 0-2 V
					After 5 seconds with ignition switch ON (II)	0 V
4	PNK/BLK	LR LF SIG. (LR low frequency signal)	Detects the signal from the left-rear initiator	4-GND	For 5 seconds with ignition switch ON (II)	Pulses 0-2 V
