BCS COMBINATION SWITCH READING SYSTEM BCS-11 < SYSTEM DESCRIPTION > [BCM] C D E F G H I J K L B A O P N COMBINATION SWITCH READING FUNCTION Description • BCM reads the status of the combination switch at 10ms intervals normally. NOTE: BCM reads the status of the combination switch at 60ms intervals when BCM is controlled at low power con- sumption mode. • BCM operates as follows and judges the status of the combination switch. - It operates the transistor on OUTPUT side in the following order: OUTPUT 1 → 2 →3 →4 →5 and outputs voltage waveform. - The voltage waveform of OUTPUT corresponding to the formed circuit is input into the interface on INPUT side if any (1 or more) switches are ON. - It reads this change of the voltage as the status signal of the combination switch. Operation Example OUTPUT 4 — INT VOLUME 3 AUTO LIGHT — TAIL LAMP OUTPUT 5 INT VOLUME 2 — — FR FOG — System INPUT 1 INPUT 2 INPUT 3 INPUT 4 INPUT 5 JPMIA0609GB JMMIA0326GB |
