BCS-6 < SYSTEM DESCRIPTION > COMBINATION SWITCH READING SYSTEM NOTE: Headlamp has a dual system switch. COMBINATION SWITCH READING FUNCTION Description • BCM reads the status of the combination switch at 10 ms interval normally. NOTE: • BCM operates as follows and judges the status of the combination switch. → 4 → 3 → 2 → 1. - The voltage waveform of INPUT corresponding to the formed circuit changes according to the operation of the transistor on OUTPUT 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 In the following operation example, the combination of the status signals of the combination switch is replaced INPUT 3 INT VOLUME 1 — — HEADLAMP 2 HI BEAM INPUT 4 — INT VOLUME 3 AUTO LIGHT — TAIL LAMP INPUT 5 INT VOLUME 2 — — — — System OUTPUT 1 OUTPUT 2 OUTPUT 3 OUTPUT 4 OUTPUT 5 JPMIA0067GB JPMIA0068GB |
