EXL-22 < SYSTEM DESCRIPTION > COMBINATION SWITCH READING SYSTEM Combination switch circuit Combination switch INPUT-OUTPUT system list 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 reads the status of the combination switch at 20 ms interval when BCM is controlled at low power con- sumption control mode. • BCM operates as follows and judges the status of the combination switch. - INPUT 1 - 5 outputs the voltage waveforms of 5 systems simultaneously. - It operates the transistor on OUTPUT side in the following order: OUTPUT 5 → 4 → 3 → 2 → 1. System OUTPUT 1 OUTPUT 2 OUTPUT 3 OUTPUT 4 OUTPUT 5 INPUT 1 — FR WASHER FR WIPER LOW TURN LH TURN RH INPUT 2 FR WIPER HI — FR WIPER INT PASSING HEADLAMP 1 INPUT 3 INT VOLUME 1 RR WASHER — HEADLAMP 2 HI BEAM INPUT 4 RR WIPER INT INT VOLUME 3 AUTO LIGHT — TAIL LAMP INPUT 5 INT VOLUME 2 RR WIPER — FR FOG — LIIA0760E JPMIA0067GB 2011 Pathfinder |
